Notes
  1. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
  2. Isat: DC current that causes the primary inductance drop of 30% (typ) from its value without current.
  3. Leakage inductance is for the primary winding with the secondary windings shorted.
  4. Isolation (hipot) measured between windings for one minute.

Termination:

  • RoHS tin-silver-copper over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (175 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.
