Notes:
Height=1.22" Max
Length=1.2" Max
Polyurothane Coated
Marked: WILCO + Part#
Pin Connections are 1 + 3
No Pin Connections on 2 + 4
Inductance measured at 1KHz 0 amps DC
Inductance is +/- 15% at 1 KHz 0 amps DC
Nonstandard values available
Operating temperature is -55 degrees C to 100 degrees C
Saturation currents shown indicate the max drop in L at that current
Features:
Vertical base mounted toroids provide greater mechanical stability and easy PCB installation
Typical applications are switching power supplies, filters, output chokes, EMI/RFI filtering
The torodial configuration provides a closed magnetic field resulting in low EMI
