TSP-EP13 SERIES（1-3）

POE Transformer

Designed for forward topology operating at 250 kHz.
Three different outputs: 3.3 V, 5.0 V and 12 V.
Isolation: 1500 Vrms, one minute primary and bias to secondary.
Operating temperature range: -40°C~+125°C, self-temperature rise included.
33 – 57 V input; excellent for PoE applications.

Notes:

1. All electrical specifications are referenced to 25°C ± 5°C ambient.
2. The inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 ADC.
3. The leakage inductance is for the primary with the secondary winding shorted.
4. DCR for the secondary is measured with the windings connected in parallel.
5. Turns ratio is with the secondary windings connected in parallel.
6. Output is with the secondary windings connected in parallel. Output of the bais winding is 12 V, 20 mA.
