Notes

Output is with the secondary windings connected in series. Bias winding output is 10 V, 65 mA.
When ordering, please specify a packaging code: HA4000-ALD.
Inductance is for the primary, measured across pins 2 and 4 at 200 kHz, 0.1 Vrms, 0 Adc.
DCR for the primary is measured from pin 2 to pin 4. DCR for the secondary is for each winding.
Leakage inductance is for the full primary and is measured with the secondary shorted.
1500 Vdc isolation, primary and auxiliary to secondaries.

Termination:

RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.

Packaging:

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