Hinweise

When ordering, please specify packaging code: e.g. POE300F-24LD
Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
Ipk is the peak primary current drawn at minimum input voltage.
DCR is with the windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary with the secondary windings shorted.
Turns ratio is with the primary and the secondary windings connected in parallel.
Isolation: 1500 Vrms primary to secondary; 500 Vrms primary to auxiliary.
Output is with the secondary windings connected in parallel. Output of the auxiliary winding is 12 V.

Anschlüsse:

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

Verpackung:

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).
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.
