1. When ordering, please specify
testing
code:
ML425PJB105MLZ
Testing: Z
= COTS
H
= Group A screening per Coilcraft
CP-SA-10001
N
= Group A screening per Coilcraft
CP-SA-10004
Custom screening also available
2. Inductance tested at 100 kHz, 0.1 Vrms using
an Agilent/HP 4192A. Inductance at 1 MHz is
the same for parts with SRF
≥10
MHz.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 8753ES or
equivalent.
5. Typical DC current that causes the specified
inductance drop from its value without current.
6. Typical current that causes the specified tem-
perature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Com-
ponents” before soldering.
