Notes: 1. Tested at 100kHz, 1Vrms series. 2. Electrical specifications at 25°C. 3. Operating range: -40°C to +130°C. This is a combination of ambient plus temperature rise. 4. DC current through winding to cause a 40°C temperature rise at 25°C ambient. 5. DC current through the winding to cause a 25% drop in inductance 6. All products are RoHS-compliant. 7.
