1. Inductance tested at 100 kHz, 0.1 Vrms on Agilent/HP 4192A.

2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.

4. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maxi-

5. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

• High current, high inductance power inductors

• Designed for high current power supply applications

• Flat wire windings provide extremely low DC and AC resistance.

• Suitableforhightemperatureenvironments,upto125°Cambient

• AEC-Q200 Grade 1 qualified (−40°C to +125°C)

• Shield has solderable tabs for additional mounting stability.

3. SRF measured on an Agilent/HP 8753ES network analyzer.

5. DC current at 25°C that causes an inductance

drop of 30% (typ) from its value without current.
