Notes

When ordering, please specify packaging code: e.g. CST4835-150EC
Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
Volt-time product is for the secondary, between pin 1 and 2.
For specific questions regarding frequency range, please contact us at [email protected].
Primary current of 7 A causes approximately 25°C temperature rise above 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
Terminating resistor value is based on 1 Volt output with 7 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T (Ohms) = V_out × N_sec / I_in.
500 Vrms, one minute isolation (hipot) winding to winding.

Termination:

RoHS compliant tin-silver over tin over nickel over copper (pins 2 – 1); RoHS compliant tin over nickel over copper (pins 4 – 3).

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 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 C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (2200 parts per full reel).
