1. Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape. (900 parts per full reel). Quantities less than full reel available: in
tape (not machine ready) or with leader and trailer ($25 charge).
2. Inductance is for primary windings measured at 100 kHz, 0.01Vrms, 0 Adc.
3. Leakage inductance is measured between pins 1 and 3 at 100 kHz,
0.1 Vrms with secondary pins shorted.
4. Volt-time product is for primary windings, between pin 1 and 3.
5. One minute isolation (hipot) primary windings to secondary windings.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
