1 Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc.
2 Leakage inductance measured across the primary at 100 kHz, 0.1 Vrms, 0 Adc.
3 Isolation tested between primary and secondary and between auxiliary and secondary windings.
4 Ambient temperature range: −40°C to +85°C
5 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
6 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
7 Electrical specifications at 25°C.
