Notes
- When ordering, please specify termination code: e.g. ST420FRC104NRZ.
- Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4263B LCR meter and a Coilcraft CCF 1113 fixture.
- Current per winding that causes a 25°C rise from +125°C ambient.
- DCR is specified per winding, measured at on a Keithley 580 microohmmeter and a Coilcraft CCF 858 fixture.
- Winding to winding isolation (hipot) tested for one minute.
Termination:
- R = Matte tin over nickel over silver-platinum glass frit.
- P = Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit.
- Q = Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit.
