Notes

Output of the secondary is with the windings connected in parallel. Aux winding output is 2.5 V, 20 mA.
When ordering, please specify packaging code: e.g. MA5237-ELD
Inductance is for the primary, measured at 500 kHz, 0.1 Vrms.
Peak primary current drawn at minimum input voltage.
DCR for the secondary is measured with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary winding with the secondary windings shorted.
Turns ratios are with the secondary windings connected in parallel.
3500 Vrms, one minute isolation primary to secondary windings.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (200 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
