1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic

tape (175 parts per full reel). Quantities less than full reel

available: in tape (not machine ready) or with leader and

trailer ($25 charge).

2. Inductance for is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.

3. Minimum inductance for the primary, measured at 250 KHz, 0.2 Vrms,

3.5 Adc.

4. Leakage inductance is for the primary winding with the secondary

windings shorted.

5. Isolation (hipot) is measured for one minute: 1500Vrms from primary

and aux/bias to secondary; 500Vrms from primary to aux/bias.

6. Electrical speciﬁcations at 25°C.
