注释

Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc.
DC current applied to the primary at 25°C that causes an inductance drop of <10% from its value without current.
Leakage inductance is for the primary with the secondary and aux windings shorted.
1500 Vrms, one minute isolation (hipot) between primary and auxillary to secondary.
Output is for the secondary. Output of the aux winding is 12 V, 30 mA.

端子:

RoHS-compliant, halogen free. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronze terminations.

包装:
