Notes
- When ordering, please specify screening code: e.g. ST629TCB1200LZ.
- Inductance measured between secondary pins 2 - 4 at 1 kHz, 0.1 Vrms, 0 Adc.
- 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 (RT) 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: RT = Vout × Nsec/Iin.
Termination:
- L = Tin-silver over tin over nickel over phos bronze (pins 1-10); Matte tin over nickel over copper (pins 11-12)
Screening:
- Z = Unscreened
- H = Coilcraft CP-SA-10001 Group A
- Screening performed to the document’s latest revision.
- Custom testing also available.
- Country of origin restrictions available; prefix options G
