1. Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (600 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 the primary, measured between pins 4 and 1 with pins
2 and 3 connected at 1 MHz, 0.1 Vrms, 0 Adc.
3. DCR is per winding.
4. Leakage inductance is for the primary with both windings connected in
series and with the secondary windings shorted.
5. Volt-time product is for the primary, between pins 4 and 1 with pins 2
and 3 connected.
6. Calculated Output Power will vary depending upon application.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
