Notes

When ordering, please specify packaging code: e.g. CU8965-ALC
Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
Volt-time product is for the secondary, between pin 1 and 2.
For specific questions regarding frequency range, please contact us at [email protected].
Primary current of 20 A causes approximately 25°C temperature rise above 25°C ambient (see Temperature Rise vs Current curve).
Terminating resistance (R_T) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T (Ohms) = V_out × N_sec / I_in.
1000 Vrms, one second isolation (hipot) winding to winding.

Termination:

RoHS-compliant, halogen free. 260°C compatible. Tin-silver-copper over tin over nickel over copper.

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel).
