| 1 | Inductance is for the primary, measured at 50 kHz, 0.1 Vrms, 0 Adc. | |
| 2 | Peak primary current drawn at minimum input voltage. | |
| 3 | DCR 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 50 kHz, 0.1 Vrms, 0 A with secondary windings shorted. | |
| 5 | Ambient temperature range: | −40°C to +85°C |
| 6 | Storage temperature range: | Component: −40°C to +85°C Packaging trays: −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 | ||
