1. The rated inductance per phase is determined by Volterra’s testing and circuit design. Additional
information can be provided by contacting Volterra.
2. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ 25°C
3. Short-Circuit Inductance (SCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ 25°C
4. Full Load Inductance (FLL) for (SCL), 100kHz, 1.0Vrms, 50 Adc, @ 25°C
5. Irms DC current per phase that will cause a 40°C temperature rise without core loss at 25°C
ambient. It is recommended the temperature not exceed 125°C under worse case operating
conditions verified in the end application.
