Notes
  1. When ordering, please specify termination and packaging codes: e.g. CST1-125LC or CST2-125LC
  2. Inductance measured across secondary at 100 kHz, 0.1 Vrms.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Volt-time product is for the secondary, between pin 6 and 4 for CST1 and between pin 1 and 3 for CST2.
  5. For specific questions regarding frequency range, please contact us at [email protected].
  6. Primary current of 20 A causes approximately 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise. (see Temperature Rise vs Current curve).
  7. Terminating resistor value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT (Ohms) = Vout × Nsec / Iin.
  8. 500 Vrms, one minute isolation (hipot) winding to winding.

Termination:

  • L = RoHS compliant tin-silver over tin over nickel over phos bronze (pins 1 – 6); RoHS compliant Matte tin over nickel over copper (pins 7 – 8).
  • S = non-RoHS tin-lead (63/37) over tin over nickel over phos bronze (pins 1 – 6); non-RoHS tin-lead over gold over nickel over copper (pins 7 – 8). (Special order, added cost)

Packaging:

  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 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 C.

Schematics

CST1 Series
cst1schematic.gif
Terminating resistor (RT)value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT (Ohms) = Vout × Nsec / Iin.

CST2 Series
