注释

Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc.
DC current at 25°C that causes an inductance drop of <15% (POExx51Q) and <15% (POExx40Q) from its value without current.
Leakage inductance is for the primary with the secondary and aux windings shorted.
1500 Vrms, 1 minute isolation (hipot) between primary and auxillary 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:
