Notes
- When ordering, please specify termination and screening codes: e.g. ST630TCB1300LZ.
- Inductance measured between secondary pins at 10 kHz, 0.1 Vrms, 0 Adc.
- Volt-time product is for the secondary, between pin 3 and 1.
- Primary current of 40 A causes less than 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-copper over tin over copper over steel (pins 1 – 3); Tin-silver-copper over tin over nickel over copper (pins 4 – 5)
- S = Tin-lead over tin over copper over steel (pins 1 – 3); Tin-lead over tin over nickel over copper (pins 4 – 5)
Screening:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
- Screening performed to the document’s latest revision.
- Custom testing also available.
- Country of origin restrictions available; prefix option G.
