1 Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.
2 Ipk: Peak primary current drawn at minimum input voltage.
3 DCR for the primary is measured with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance is for the primary winding, measured at 100 kHz, 0.1 Vrms with the secondary winding shorted.
5 Output is for the secondary winding. Bias winding output is 12 V, 20 mA.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +85°C
Packaging tray: −40°C to +80°C
8 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.
9 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.
