" Chip Ferrite Beads are effective for frequencies ranging
from a few MHz to a few GHz. Chip Ferrite Beads are
widely used as a low noise countermeasure, as well as a
universal noise suppression component.
" Chip Ferrite Beads produce a micro inductance in the low
frequency range. At high frequencies, however, the
resistive component of the inductor produces the primary
impedance. When inserted in series in the noise
producing circuit, the resistive impedance of the inductor
prevents noise propagation.

" This capacitor type EMI suppression filter has a large
noise suppression effect at frequencies ranging from a
few MHz to hundreds of MHz. This type of filter is used
widely as a universal, high performance EMI suppression
component.
" The chip EMIFILr incorporates a built-in three-terminal
capacitor, eliminating the lead wire and thereby
increasing the high-frequency performance characteristic.
" The T-type chip EMIFILr is a chip EMI suppression filter
with a built-in feed-thru capacitor. The use of ferrite
beads on input and output terminals minimizes
resonance with surrounding circuits.
" Whatever the situation, 3-terminal construction reduces
residual inductance, thereby substantially improving
noise suppression at frequencies over 10MHz.

" High-speed signal application EMIFILr are high performance EMI suppression filters which increase the slope
of insertion loss frequency characteristic curves (shape
factor), thereby improving noise and signal separation.
These are used for high speed signal applications in
which noise and signal frequency approach the same
value.
To avoid the elimination of both the noise and specific
signal components, 3-terminal capacitors and other
components are applied.
An NFW31S with a built-in capacitor and an inductor type
BLM--B are available.
BLM18HD has additional performance for suppressing
GHz range noise after cut off frequency.
" The EMIFILr with waveform distortion suppressing function suppresses waveform distortion caused by the resonance of digital ICs and surrounding circuits.

On-Board Type (DC) EMI Suppression Filters(EMIFILr)
Chip Ferrite Bead BLM Series
Essential for Noise Suppression in High Speed Signal
Lines and DC Power Lines
The chip ferrite bead BLM series comprises ferrite beads in
the shape of a chip. This ferrite bead generates a high
impedance which at high frequencies mainly consists of a
resistance element. The BLM series is effective in circuits
without stable ground lines because the BLM series does
not need a connection to ground.
Chip sizes of 0.6Z0.3, 1.0Z0.5, 1.6Z0.8, 2.0Z1.25, 3.2Z1.6
and 4.5Z1.6mm are cataloged. (The BLA series of array
type chip ferrite beads is also cataloged.)
The nickel barrier structure of the external electrodes
provides excellent solder heat resistance.
!Features
The BLM series comprises the R series (for digital interface),
the A series (for standard), the B series (for high speed
signal), the P series (for large current), and the H/E series
(for GHz range noise suppression).
1. BLM--R series – For Digital Interface
The BLM-R series can be used in Digital Interface.
Resistance of BLM-R series especially grows in the lower
frequency range. Therefore BLM-R series is less effective
for digital signal waveform at low frequency range and
can suppress the ringing.
2. BLM--A series – For Standard
The BLM-A series generates an impedance from the
relatively low frequencies. Therefore the BLM-A series is
effective in noise suppression in the wide frequency
range (30MHz – several hundred MHz).
3. BLM--B series – For High Speed Signal
The BLM-B series can minimize attenuation of the signal
waveform due to its sharp impedance characteristics.
Various impedances are available to match signal
frequency.
4. BLM--P series – For Large Current
The BLM-P series can be used in high current circuits
due to its low DC resistance. It can match power lines to
a maximum of 6A DC (BLM41P).
5. BLM18H/E series – For GHz Range Noise Suppression
The BLM18H/E series has a modified internal electrode
structure that minimizes stray capacitance and increases
the effective frequency range.

On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Ferrite Beads BLM03/BLM15/BLM18/BLM21/BLM31/BLM41 Series
■ Features (BLM_A Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequency
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
BLM_A series generates an impedance from the
relatively low frequencies. Therefore BLM_A series is
effective in noise suppression in a wide frequency
range (30MHz - several hundred MHz).
The small size of BLM03 series (0.6x0.3mm) is
suitable for noise suppression in small equipment
such as PA modules for cellular phones.
■ Equivalent Circuit
(Resistance element becomes dominant
at high frequencies.)

■ Features (BLM_B Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequencies
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_B series can minimize attenuation of the
signal waveform due to its sharp impedance
characteristics. Various impedances are available to
match signal frequency.
■ Equivalent Circuit

(Resistance element becomes dominant
at high frequencies.)

■ Features (BLM_R Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequencies
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_R series can be used in a digital interface.
Resistance of BLM_R series especiallly grows in the
lower frequency range. Therefore BLM_R series is less
effective for digital signal waveform at low frequency
range and can suppress the ringing.

On-Board Type (DC) EMI Suppression Filters (EMIFILr)
GHz Noise Suppression Chip Ferrite Beads BLM18H/BLM18E Series
BLM18H/BLM18E series has a modified internal electrode
structure, that minimizes stray capacitance and
increases the effective frequency range.
1
■ Equivalent Circuit
■ Features (BLM18H series)
1. BLM18H series is realized high impedance at 1GHz
and suitable for noise suppression from 500MHz to
GHz range. The impedance value of HG/HD-type is
about three times as large as that of A/B-type at
1GHz, though the impedance characteristic of
HG/HD-type is similar to A-type at 100MHz or less.
2. HG-type is effective in noise suppression in wide
frequency range (several MHz to several GHz).
HB/HD-type for high-speed signal line provides a
sharper roll-off after the cut off frequency.
HK-type for digital interface is effective in
suppressing the ringing because resistance
especially grows in the lower frequency.
3. The magnetic shielded structure minimizes crosstalk.
(Resistance element becomes dominant
at high frequencies.)
■ Features (BLM18E series)
1. Low DC Resistance and a large Rated Current are
suitable for noise suppression of the driver
circuit.
2. Excellent direct current characteristics
3. Thin type (t=0.5mm) is suitable for small and low
profile equipment such as DSC, cellular phones.

(Bottom View)
1. Murata's original inner design realizes small and
low profile of 2.0x1.25x0.5mm.
2. Distributed constant circuit realizes smooth change
of impedance which prevents reflection of signal
and distortion of wave shape.
3. The NFR21G series is effective in a line where
ground is not stable, because the resistance
element in the filter absorbs noise and returns it to
ground line.
4. The NFR21G series has no polarity so it can be used
in dual direction transport lines.
5. The NFR21G series has various lineups of resistance
(22 to 100ohm) and capacitance (10 to 100pF).

The signal line chip EMI filter NFW31S series consists
of high performance EMI suppression filters. They are
designed for noise suppression in high speed signal
digital circuits in which the signal harmonics are
prone to becoming noise sources. These filters achieve
a 100dB/dec. (typ.) damping characteristic with
Murata's innovative circuit design. This makes these
chips effective in applications where the signal and
noise frequencies are close to each other.

On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Ferrite Beads Inductors BL01/BL02/BL03 Series
■ Features
ø3.6±0.15
BL01/02/03 series are ferrite beads with lead wires to
produce a high frequency loss for suppression of
noise. Simple construction and easy-to-use.
Effective for low impedance circuits such as power
supplies and grounds. Effective also for preventing
overshoot and undershoot the digital signal in clocks
or the like, and suppressing the higher harmonic wave.
Suitable for prevention of abnormal oscillation at
high frequency amplifying circuit.

The 2-terminal capacitor is influenced
by lead line inductance, leaving behind
some of the rising and falling edges.
The residual noise can cause the
system to malfunction.
The 3-terminal structure eliminates
most of the lead line inductance. This
allows the VFS9V to completely absorb
the rising and falling edges of the
applied pulses.

are saturated. In this example, the
residual 1200V surge can cause the

EMIFILr (Soldering and Mounting)
1. Standard Land Pattern Dimensions
The capacitor type Chip EMIFILr (NFp series) / Chip EMIGUARDr (VFM series) suppress noise by conducting the highfrequency noise element to ground. Therefore, to obtain maximum performance from these filters, the ground pattern should
be made as large as possible during the PCB design stage. As shown in the right, one side of the PCB is used for chip
mounting, and the other is used for grounding.
Small diameter feedthrough holes are then used to connect the grounds on each side of the PCB. This reduces the highfrequency impedance of the grounding and maximizes the filter's performance. Please contact us if using a thinner land pad
than 18µm for NFM55P.

2. Solder Paste Printing and Adhesive Application
When reflow soldering the chip EMI suppression filter, the
printing must be conducted in accordance with the
following cream solder printing conditions.
If too much solder is applied, the chip will be prone to
damage by mechanical and thermal stress from the PCB
and may crack. In contrast, if too little solder is applied,
there is the potential that the termination strength will be
insufficient, creating the potential for detachment.
Standard land dimensions should be used for resist and
copper foil patterns.
When flow soldering the EMI suppression filter, apply the
adhesive in accordance with the following conditions.
If too much adhesive is applied, then it may overflow into
the land or termination areas and yield poor solderability.
In contrast, if insufficient adhesive is applied, or if the
adhesive is not sufficiently hardened, then the chip may
become detached during flow soldering process.

2. Using THE block type EMIFILr effectively
The block type EMIFILr effectively prevents unwanted
reflections and external noise from entering the
equipment circuitry and power lines by grounding all the
high frequency components which make up the noise.
Therefore, if grouding is improperly done, the filters may be
unable to achieve the performance they are capable of.
To prevent this, be sure to observe the following instructions.
(1) When designing the P.C. board, use all the available
grounding terminals, and arrange the grounding circuit
so that the area of the foil for the grounding circuit is
maximized.
(2) Minimize the distance between the P.C. board ground
and the filter's grounding plate. Use through-hole P.C.
boards.
(3) Whichever P.C. board is used, push the filter into the
P.C. board up to the terminal roots.
(4) Do not connect PSG to CG by any other means except
through the filter. (See the item 1. TERMINAL LAYOUT)

Noise Suppression Principles by DC EMIFILr
1. Function of DC EMI Suppression Filters
DC EMI suppression filters absorb and eliminate high frequency noise which may produce electromagnetic
interference in PC board circuits.
These filters are used in secondary circuits, and are small
in size and light in weight, which further enhances their
excellent noise suppression functions.
Chip and adhesive type filters can be mounted on PC
boards automatically.
These filters are effective in the suppression of radiation
noise in computers, peripheral equipment, and digital
circuit application equipment (including various types of
microcomputer application equipment), and function to
suppress noise in audio/visual equipment, which uses
digital memory chips and DSP.
These filters are also effective for improving the noise
immunity of equipment used in noisy environments (such
as electronic equipment for automobiles).
2. Noise Filter Suppression Principles
Generally, noise problems occur when the noise source
and electronic equipment sensitive to the influence of
noise are located in close proximity to one another.
In such situations, as shown in Figure at right, noise is
conducted through a conductor, which produces an
inductive field around the noise source.
To overcome such noise problems, it is preferable to
reduce the amount of noise generated by the noise
source or improve the noise resistance of adjacent
equipment.
In order to satisfy equipment performance specifications
and eliminate noise effectively at the same time, however,
it is customary to reduce the amount of noise generated
by the noise source, if it can't be eliminated altogether.

3. Configuration of EMI Suppression Filters (DC)
DC EMI suppression filters are used to suppress noise
produced by conductors. Noise radiation can be
suppressed, if it is eliminated with a filter in advance.
Generally, such noise suppression is achieved with DC
EMI suppression filters, according to the capacitive and
inductive frequency characteristics of the respective
conductors in the circuit.
Filters of this kind can be roughly divided into those :
(1) employing a capacitor,
(2) employing an inductor,
(3) employing a capacitor and inductor combination.

Noise Suppression Principles by DC EMIFILr
Continued from the preceding page.
4. Capacitive Noise Suppression
When a capacitor is connected (bypass capacitor) to
ground from a noisy signal line or power line, the circuit
impedance decreases as the frequency increases. Since
noise is a high frequency phenomenon, it flows to ground
if a capacitor has been connected to ground, thereby
making it possible to eliminate noise. (See Fig.)
EMI suppression filters employing a capacitor in this way
are used to eliminate this type of noise.
5. High frequency Capacitor Characteristics Used
for EMI Suppression Filters
Even general-purpose capacitors can be used for noise
suppression. However, since noise has an extremely high
frequency range, general-purpose capacitors may not
function as effective bypass capacitors, due to the large
residual inductance built into the capacitor.
All the capacitors used in MURATA's EMI suppression
filters employ a 3 terminal structure or thru-type structure,
which functions effectively even at high frequencies,
thereby minimizing the influence of residual inductance.
Consequently, an effective filter circuit can be formed
even at frequencies exceeding 1GHz. (Refer to Fig.)

6. Inductive Noise Suppression
When an inductor is inserted in series in a noise
producing circuit (See Fig.), its impedance increases with
frequency. In this configuration it is possible to attenuate
and eliminate noise components (high frequency
components). The MURATA EMI suppression filter
functions in this way.

Noise Suppression Principles by DC EMIFILr
Continued from the preceding page.
General-purpose inductors also function to suppress
noise when configured in series with a noise producing
circuit. However, when general-purpose inductors are
used, resonance may result in peripheral circuits, signal
wave forms may become distorted, and satisfactory
impedance may not be obtained at noise frequencies
(due to insufficient high frequency impedance
characteristics).
The inductors used for MURATA's EMI suppression filters
are designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of
resonance and leaves signal wave forms undistorted.
And since sufficient impedance is obtained for
frequencies ranging to hundreds of MHz, these
specifically designed inductors operate effectively to
suppress high-frequency noise. (See Fig.)

8. Capacitive-Inductive EMI Suppression Filters
If capacitive and inductive suppression characteristics are
combined, it is possible to configure a much higher
performance filter. In signal circuit applications where this
combination is applied, noise suppression effects which
have little influence on the signal wave form become
possible.
This type of filter is also effective in the suppression of
high-speed signal circuit noise. When used in DC power
circuits, capacitive-inductive filters prevent resonance
from occurring in peripheral circuits, thus making it
possible to achieve significant noise suppression under
normal service conditions.
9. Other EMI Suppression Filters
In addition to the capacitive-inductive filter, MURATA also
has an EMI suppression filter (EMIGUARDr) combining
a capacitor with a varistor, useful for surge absorption;
and a common mode choke coil effective, for common
mode noise suppression.
MURATA also has a range of built-in filter connectors
which greatly reduce filter mounting space requirements.

10. Expressing EMI Suppression Filter Effects
EMI Suppression Filter effects are expressed in terms of
the insertion loss measured in the circuit, normally
specified in MIL-STD 220A. As shown in the 50Ω
impedance circuit in the Figure at right, insertion loss is
represented by the logarithmic ratio of the circuit output
voltage with and without a filter in the circuit, which is
multiplied by 20 and expressed in dB.
Therefore, an insertion loss of 20dB indicates an output
voltage ratio (B/C) of 1/10, and an insertion loss of 40dB
indicates an output voltage ratio (B/C) of 1/100.
