Notes

When ordering, please specify packaging code: e.g.CST2010-200LD
Inductance measured between secondary pins at 1 kHz, 0.1 Vrms, 0 Adc.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Volt-time product is for the secondary, between pin 2 and 4.
For specific questions regarding frequency range, please contact us at [email protected].
Primary current of 47 A causes approximately 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
Terminating resistance (R_T) value is based on 1 Volt output with 40 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T= V_out × N_sec / I_in.
1500 Vrms, one minute isolation (hipot) winding to winding.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze (pins 1-10); Matte tin over nickel over copper (pins 11-12).

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (300 parts per full reel).
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.
