Notes
  1. Inductance measured between secondary pins at 1 kHz, 0.1 Vrms.
  2. Volt-time product is for the secondary, between pin 4 and 3.
  3. For specific questions regarding frequency range, please contact us at [email protected].
  4. Primary current that causes approximately 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 100 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. 5000 Vrms, one minute isolation (hipot) winding to winding.

Termination:

  • E = RoHS compliant tin-silver-copper over copper (pins 1 – 2); RoHS compliant tin-silver-copper over matte tin over nickel over phos bronze (pins 3 – 4).

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (90 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.
