1. When ordering, please specify testing code:
ML338PWA±±4MLZ
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A or equivalent.
5. DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise fron 25°C ambient.
7. Electrical specifications at 25°C.
Testing: Z =COTS
H =Screening per Coilcraft CP-SA-10001
N =Screening per Coilcraft CP-SA-10004
