Chip Inductors–ML235RAA (0402)
Current Derating

100
This 0402 size chip inductor series shares all of the
characteristics of Coilcraft’s other ceramic inductors: ex-
ceptionally high Q factors, especially at use frequencies;
outstanding self-resonant frequency; tight inductance tol-
erance; and excellent batch-to-batch consistency.
This robust version of Coilcraft’s standard 0402CS series
features a high temperature encapsulant that allows op-
eration in ambient temperatures up to 155°C.

1. When ordering, please specify
tolerance
and
testing
codes:
ML235RAAR10GLZ
Tolerance: G
= 2%
J
= 5%
Testing:
Z
= Coilcraft Critical Products Environmental Stress
Conditions Testing.
H
= CP-SA-10001 screening in addition to Critical
Products Environmental Stress Conditions Testing.
N
= MIL-STD-981 Class B screening in accordance with
Coilcraft CP-SA-10003.
C
= MIL-STD-981 Class S qualification / screening in
accordance with Coilcraft CP-SA-10003.
2. Inductance measured at 250 MHz using a Coilcraft SMD-F test
fixture and Coilcraft-provided correlation pieces with an Agilent/
HP 4286 impedance analyzer.
3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193
test fixture.
4. For SRF >6 GHz, measured using an Agilent/HP 8722ES network
analyzer and a Coilcraft SMD-D test fixture. For SRF
≤6
GHz,
measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DCR measured on a micro-ohmmeter.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
