Notes

1. Inductance measured at 100kHz, 100mV.

2. Rated current is the current at which the temperature rise is 45ºC.

3. Saturation current, Isat, is the DC current at which the zero-current inductance falls by 10%.

For this family, inductance falls by around 25% for a current of 2x Isat.

4. Operating temperature -25ºC to +105ºC.

5. For non-standard inductance values, please contact Profec.
