Ceramic Capacitors
we offer performance and
cost alternatives to meet
varied voltage, capacitance,
packaging and budgetary
requirements
Discoidal Feed-Through Capacitors
are ideal for by-pass and filtering
applications with a low inductance
construction suited for high frequency
applications. Their low profile and
rugged design is an excellent
alternative to ceramic tubes… CC3-CC7
Tubular Feed-Through Capacitors
are small and lightweight with high dielectric
strength and are impervious to moisture and
contamination. Feed-through capacitors have
a uniform insertion loss over a broad spectrum
range and are ideal for multi-pin connector
applications… CC8-CC9
Tubular Pi Capacitors have similar
characteristics to feed-through capacitors
in addition to a narrower transition between
the pass and stop bands, effectively
stopping high frequency interference
without affecting desired frequencies
and providing filtering of noise content
close to signal content … CC10-CC11
SMPS (Switch Mode Power Supply)
Capacitors deliver lower equivalent
series resistance, lower equivalent series
inductance, lower ripple voltage and less
self-heating when compared to other
capacitive elements… CC13-CC16
Planar Capacitors offer a faster assembly
time compared to stand-alone chips, discoidal
or tubular capacitors. They also have a low
profile and are capable of meeting various
geometric and electrical configurations, making
Spectrum’s planar capacitors the new standard
in EMI suppression applications… CC17
API Technologies’ Expertise
Inside every EMI filter is a ceramic feedthrough capacitor. The Spectrum Control
line of ceramic capacitors is designed to
provide solutions to a wide range of filtering
applications. Our ceramic capacitors are
ideal for EMI/RFI suppression filters,
medical implantable devices, commercial
and military applications, power supplies
and converters.

Discoidal Capacitors
Ceramic discoidal feed-through capacitors are the
building blocks of the EMI filter industry. API’s Spectrum
Control discoidal capacitors provide great versatility
in meeting varied voltage, capacitance and dimensional
requirements. Our nonpolar, multilayer capacitors are
small, reliable and high in dielectric strength. Operational
temperatures of –55°C to +125°C are achieved with no
voltage de-rating.
The versatile nature of our discoidals makes them ideally
suited for by-pass and filtering applications. Due to their
low inductance construction, these capacitors perform
extremely well in high frequency applications. The circular
geometry of a discoidal feed-through capacitor offers
many paths to ground, resulting in lower impedance
and better filtering performance.
The low profile and rugged design of our discoidal
capacitors offer an excellent alternative to ceramic tubes.

Tubular FT Capacitors
API Technologies’ Spectrum Control brand manufactures
a wide variety of tubular feed-through (FT) ceramic
capacitors, which are small in size, lightweight, nonpolar
and offer high dielectric strength. Operating temperatures
of –55°C to +125°C are achieved with no voltage de-rating.
All capacitors are fired to produce true monolithic structures,
which are impervious to moisture and contamination.
Outer terminations feature a nickel barrier and a final
metal layer, typically silver.
Feed-through tubular capacitors are ideally suited for
by-pass and filtering applications. Due to the cylindrical
design, the capacitors will have uniform insertion loss
over a broad frequency range. This structure yields
a low inductance when compared to conventional
wound capacitors.
Solid FT capacitors have no internal electrodes
and find their primary usage in low cost applications.
Multilayered FT capacitors have a higher capacitance
to volume ratio and are ideally suited for greater filtering
at lower frequencies. Multilayered FT capacitors are
also designed for applications where source impedances
are high and sharp attenuation rise is critical.

Tubular Pi Capacitors
As with the feed-through tubular capacitors, the Pi (π)
tubular capacitors offered by API’s Spectrum Control
brand are small in size, lightweight, nonpolar and offer
high dielectric strength. Operating temperatures of -55°C
to +125°C are achieved with no voltage de-rating. All
capacitors are fired to produce true monolithic structures,
which are impervious to moisture and contamination.
Outer terminations feature a nickel barrier and a final
metal layer, typically silver.
Compared to feed-through tubular capacitors, Pi tubular
capacitors have a much narrower transition between
the pass and stop bands. Pi capacitors are effective in
stopping high frequency interference without affecting
necessary frequencies immediately below the stop band.
Similar to feed-through tubular capacitors, Pi tubular
capacitors can be designed with a solid or multilayered
configuration. Solid Pi tubular capacitors are more cost
effective, but limited in capacitance values. Multilayered
Pi tubular capacitors can cover a wider range of
capacitance, while still maintaining the mechanical
strength of a solid Pi tubular capacitor in a similar
case size.

Dielectric Characteristics
Multilayer capacitors (MLC) and single layer capacitors are
categorized by performance with temperature. Component
selection is typically determined by dielectric performance,
electrical environment and temperature stability.
In determining the proper component for a specific
application, the following information should be considered.
Dielectric Type
There are three basic dielectric classes (characteristics)
available:
DIELECTRIC PROPERTIES
Dielectric Type Stability Class
BP
Ultra Stable
(NPO and COG) Class I
BQ, BR,
BX and X7R
Z5U and Y5V
Stable
Class II
General Purpose

Dielectric Characteristics
Capacitor Selection
Description
Effects on electrical
properties are minimal with
temperature, frequency or
time. Used in applications
which require stable
performance.
Effects on electrical
properties predictably
change with temperature,
voltage, frequency and
time. Selected for
applications where blocking,
coupling, by-passing and
frequency discriminating
elements are used. Offers
higher capacitance than
Class I (COG).
Exhibits a greater variation
of properties with temperature. Dielectric constant is
higher than Class I and
Class II dielectrics.
Extremely high capacitance
per unit volume and used
in general performance
applications.

Capacitor Size
The capacitor body size impacts its utility to the
design requirements in respect to capacitance value and
voltage rating. Typically smaller units are less expensive
and provide for greater space savings. Because mass
affects the thermal response of the chips, size should
be considered when selecting the attachment method
to the circuit.

Processing & Soldering Notes
General Soldering Recommendations
for Leadless Ceramic Capacitors
Soldering Ceramic Capacitors
with High Temperature Process
Application Note: Soldering
Recommendations for Switch Mode
Power Supply Capacitors
■
SMPS capacitors are highly durable structures designed
to provide long service per lifetime, however they require
attention to basic considerations during assembly. Like
all ceramic components, SMPS capacitors are subject
to thermal stresses. For this reason, preheating of
the capacitor assemblies is recommended. Preheat
components using hot plate to 120 to 150°C, or within
50 to 60°C of the soldering temperature being applied.
Avoid over-exposure to high temperatures during
assembly and allow for gradual, post-assembly cooling.
■
For hand iron soldering, recommended soldering iron
tip temperature is 330 to 350°C. Contact the pad
adjacent to the pre-tinned lead should be made from
below the PCB (opposite of the component side),
and the dwell time on the solder joint should be less
than five seconds. An aluminum heat sink plate may
be placed adjacent to the SMPS lead frame to protect
the ceramic body during assembly. Avoid direct contact
between soldering iron and ceramic during assembly
process. Soldering time is dependant upon heat
sinking provided by the chassis and board material,
so a longer preheat cycle may be required.
■
Standard solders (Sn60, Sn63, Sn60/38/2) may be
used. Please consult the factory for use with RoHS
compliant solders.
■
Use a controlled temperature profile ramp not exceeding
4°C per second as measured by an attached low mass
thermocouple.
■
Soldering time and temperatures can vary with
component size, board material and layout.
Please consult the factory for assistance.

Notes
Care must be taken to minimize the time silver
terminations are exposed to molten solder to avoid
leaching (amalgamation of the silver into molten solder).
API recommends the use of a silver (Ag) bearing solder
when terminating directly to ceramic capacitors to reduce
the potential for leeching. Gradual heating and cooling of
the components are essential to prevent thermal stresses
to the ceramic.
