Notes

When ordering, please specify packaging code: e.g. GA3550-BLD
Inductance is for each winding, measured at 200 kHz, 0.4 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is measured at 200 kHz, 0.4 Vrms with secondary pins shorted.
SRF is per winding, measured on an Agilent/HP 4192 or equivalent.
Volt-time product is per winding.
3000 Vrms interwinding isolation
500 Vrms windings to core isolation.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze 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.
