1. Packaging: D = 13″ machine ready reel. EIA-481 embossed plastictape. Quantities less than full reel available: in tape (notmachine ready) or with leader and trailer ($25 charge).
2. Inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz,0.1 Vrms, 0 Adc.
3. Minimum inductance is for the primary, measured on an Agilent/HP 4284
at 100 kHz, 0.1 Vrms, 0.4 Adc.
4. DC current that causes an inductance drop of 30% (typ) from its value
without current
5. Leakage inductance is for the primary with secondary winding shorted
together.
6. Isolation (hipot) measured between windings for one minute
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
