Notes
  1. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
  2. Volt-time product is for the secondary, between pin 4 and 5.
  3. For specific questions regarding frequency range, please contact us at [email protected].
  4. Primary current of 28 A causes less than 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise.
  5. Terminating resistance (RT) value is based on 1 Volt output with 28 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT (Ohms) = Vout × Nsec / Iin.
  6. 3000 Vrms, one minute isolation (hipot) winding to winding.

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over nickel over copper terminations.

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).

Soldering/Washing

Moisture Sensitivity Level (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity
Resistance to soldering heat:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
