1 Inductance is for the primary, measured at 250 kHz, 0.1 Vrms
2 Peak primary current drawn at minimum input voltage.
3 DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance is for the primary and is measured at 250 kHz, 0.1 Vrms with secondary winding shorted.
5 Ambient temperature range: −40°C to +125°C
6 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
7 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.
8 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
