D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (350 parts per reel). Quantities less than full reelavailable: in tape (not machine ready) or with leader
and trailer ($25 charge).
2. Inductance is for the primary, measured at 300 kHz, 0.1 Vrms, 0 Adc.
3. Minimum inductance is for the primary, measured at 300 kHz, 0.1 Vrms,
3 Adc.
4. Leakage Inductance is for the primary, measured with secondary
windings shorted together.
5. 1500 Vrms, one minute isolation (hipot) from primary to secondary.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
