Shielded Power Inductors – VER2923
• Designed for high current power supply applications with
saturation current ratings to over 100 Amps
• Ideal for use in Class-D applications
• Flat wire windings provide extremely low DC and AC resistance
• Vertical mounting provides a small footprint

1. Inductance tested at 300 kHz, 0.1 Vrms on Agilent/HP 4192A.
2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
3. SRF measured on an Agilent/HP 8753ES network analyzer.
4. DC current at which the inductance drops the specified amount from its value without cur-
rent.
5. Current that causes the specified temperature rise of the winding from 25°C ambient.
Temperature rise of the core is usually less than that of the winding.
When Irms is greater than Isat, Isat is the more critical specification and Irms is shown in
gray type.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Caution:
This series is not intended for use
in high vibration environments. We
advise using additional means of
securing the part to the circuit board
to ensure its adhesion.
