Notes
- When ordering, please specify screening code: e.g. ST511TCB1150LZ.
- 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.
- Primary current of 20 A causes less than 25°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 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec/Iin.
