Definitions:

OCL = Open Circuit Inductance

DCR = Direct Current Resistance

Irms = rms current for approx. a 40°C temperature rise at an ambient temperature of 85°C.

*Operating Temperature: 160°C Max. Inductance values are sustained up to 160°C.

Electrical Characteristics:

OCL (1-2) 0.10Vrms, 100kHz, 0.0Adc: (See Chart)

OCL (4-3) 0.10Vrms, 100kHz, 0.0Adc: (See Chart)

DCR (1-2) typ @ 20°C: (See Chart)

DCR (4-3) typ @ 20°C: (See Chart)

Hipot rating: winding to winding: 300Vdc min. for 1 second.
