Bourns PLN Planar Transformers

Bourns PLN Planar Transformers are designed for Power over Ethernet (PoE) applications from 48W to 70W that require a low profile and high power density. Bourns PLN Planar Transformers are forward converter transformers operating at a switching frequency of 250kHz with low leakage inductance from 0.29μH to 0.6μH. The available output voltages are 5V and 12V with an output current from 4A to 14A, which can withstand hi-pot at 1750VDC

These RoHS-compliant surface-mount transformers operate over a -40°C to +125°C temperature range. The series is suitable for various applications, including forward transformers for PoE applications, industrial power systems, switched-mode power supplies (SMPS), LED lighting, and battery management systems (BMS).
