Accu-L®
SMD High-Q RF Inductor
2
10 nH Inductor (Top View)
ACCU-L® TECHNOLOGY
The Accu-L® SMD Inductor is based on thin-film multilayer
technology. This technology provides a level of control on the
electrical and physical characteristics of the component which
gives consistent characteristics within a lot and lot-to-lot.
The original design provides small size, excellent highfrequency performance and rugged construction for reliable
automatic assembly.
The Accu-L® inductor is particularly suited for the telecommunications industry where there is a continuing trend
towards miniaturization and increasing frequencies. The
Accu-L® inductor meets both the performance and tolerance
requirements of present cellular frequencies 450MHz and
900MHz and of future frequencies, such as 1700MHz,
1900MHz and 2400MHz.

Application Notes
HANDLING
PREHEAT & SOLDERING
SMD chips should be handled with care to avoid damage or
contamination from perspiration and skin oils. The use of
plastic tipped tweezers or vacuum pick-ups is strongly
recommended for individual components. Bulk handling
should ensure that abrasion and mechanical shock are minimized. For automatic equipment, taped and reeled product
is the ideal medium for direct presentation to the placement
machine.
The rate of preheat in production should not exceed
4°C/second. It is recommended not to exceed 2°C/
second.
Temperature differential from preheat to soldering should not
exceed 150°C.
For further specific application or process advice, please
consult AVX.
HAND SOLDERING & REWORK
CIRCUIT BOARD TYPE
2
All flexible types of circuit boards may be used (e.g. FR-4,
G-10) and also alumina.
For other circuit board materials, please consult factory.
COMPONENT PAD DESIGN
Component pads must be designed to achieve good joints
and minimize component movement during soldering.
Pad designs are given below for both wave and reflow
soldering.
The basis of these designs is:
a. Pad width equal to component width. It is permissible
to decrease this to as low as 85% of component width
but it is not advisable to go below this.
b. Pad overlap about 0.3mm.
c. Pad extension about 0.3mm for reflow.
Pad extension about 0.8mm for wave soldering.

CLEANING RECOMMENDATIONS
Care should be taken to ensure that the devices are thoroughly cleaned of flux residues, especially the space beneath
the device. Such residues may otherwise become conductive and effectively offer a lossy bypass to the device. Various
recommended cleaning conditions (which must be optimized
for the flux system being used) are as follows:
Cleaning liquids . . . . . . i-propanol, ethanol, acetylacetone, water, and other standard
PCB cleaning liquids.
Ultrasonic conditions . . power – 20w/liter max.
frequency – 20kHz to 45kHz.
Temperature . . . . . . . . . 80°C maximum (if not otherwise
limited by chosen solvent system).
Time. . . . . . . . . . . . . . . 5 minutes max.

After soldering, the assembly should preferably be allowed to
cool naturally. In the event of assisted cooling, similar conditions to those recommended for preheating should be used.
Recommended storage conditions for Accu-L® prior to use
are as follows:
Temperature. . . . . . . . . 15°C to 35°C
Humidity . . . . . . . . . . . ≤65%
Air Pressure . . . . . . . . . 860mbar to 1060mbar

(0.091)
Hand soldering is permissible. Preheat of the PCB to 100°C
is required. The most preferable technique is to use hot air
soldering tools. Where a soldering iron is used, a temperature controlled model not exceeding 30 watts should be
used and set to not more than 260°C. Maximum allowed
time at temperature is 1 minute. When hand soldering, the
base side (white side) must be soldered to the board.
