Notes

When ordering, please specify a packaging code: HA3648-BLD
Inductance measured on an Agilent/HP 4284 between pins 3 and 4 at 250 kHz, 0.1 Vrms, 0 Adc.
DCR for the secondary is from pin 6 to pin 10.
Leakage inductance measured between pins 3 and 4 at 250 kHz, 0.1Vrms, 0 Adc with pins 6, 8 and 10 shorted.
1500 Vdc isolation, primary to secondary.

Termination:

RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations. Other terminations available at additional cost.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (200 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 D.
