6030 POWER INDUCTORS
High Reliability Power Inductors
ML512PYA
■
High temperature materials allow operation in ambient
temperatures up to 155°C
■
Passes vibration testing to 80 G and shock testing to 1000 G
■
Exceptionally low DCR – 1.59 mOhm
■
Soft saturation makes them ideal for VRM/VRD applications.

2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A or equivalent.
5. Typical dc current at which the inductance drops 30% from its value without current.
6. Typical 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.
Irms
Testing
Irms
testing was performed on a
0.060″ thick pcb with 4 oz. copper
traces optimized to minimize ad-
ditional temperature rise.
Temperature rise is highly depen-
dent on many factors including
pcb land pattern, trace size, and
proximity to other components.
Therefore temperature rise
should be verified in application
conditions.
