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 current.
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.
6. Electrical specifications at 25°C.

• Designed for high current power supply applications
• Saturation current of 37 Amps
• Flat wire windings provide exceptionally low DC resistance
• Vertical mounting provides a small footprint
Caution:
This series is not intended for use in high vibration
or mechanical shock environments. We advise using
additional means of securing the part to the circuit
board to ensure its adhesion.
