Notes
  1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4192 or equivalent.
  2. DCR measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Impedance ratio is for the full primary winding to the full secondary winding.
  4. DC imbalance is the difference in current measured at pins 1 and 3 with the source at pin 2. Inductance drop is 15% at maximum imbalance.

Termination:

  • RoHS-compliant. Matte tin over nickel over phos bronze terminations.
  • COTS Plus tin-silver-copper and tin-lead terminations available.
