| 1 | When ordering, please specify termination code: e.g. GA3502-BL | |
| Termination: | L = RoHS compliant tin-silver over tin over nickel over phos bronze Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| 2 | Inductance is for the primary (pins 1 – 3), measured at 250 kHz, 0.3 Vrms. | |
| 3 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 4 | DCR for the primary is measured from pin 1 to pin 3. | |
| 5 | Leakage inductance is for the primary winding (pins 1 – 3) with the secondary windings shorted. | |
| 6 | Output is for the secondary. Bias winding output is 18 V, 20 mA. | |
| 7 | Ambient temperature range: | –40°C to +125°C |
| 8 | Storage temperature range: | Component: –40°C to +125°C Packaging trays: –40°C to +80°C |
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
