1. When ordering, please specify
testing
code:
ML378PJB334MLZ
Testing: Z
= COTS
H
= Group A screening per Coilcraft CP-SA-10001
N
= Group A screening per Coilcraft CP-SA-10004
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 an Agilent/HP 8753ES or equivalent.
5. DC current that causes the specified inductance drop from its value
without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
