COILCRAFT ML338PWA501MLZ

2010 POWER INDUCTORS
High-Reliability Power Inductors ML338PWA
■ High temperature materials allow operation in ambient
temperatures up to 155°C
■ Very low DCR and excellent current handling.
■ Soft saturation makes them ideal for VRM/VRD applications.
■ Special construction allows it to pass vibration testing to
30 G and shock testing to 500 G.

1. When ordering, please specify testing code:
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
