Bourns PLR Planar Transformers

Bourns PLR Planar Transformers are suitable for low-profile, 25W power-over-Ethernet (PoE) applications that require a DC-DC transformer. These surface-mount forward converter transformers provide a 25W power rating with a low maximum leakage inductance of 0.216µH and offer output voltages ranging from 5V to 12V. Ideal applications for PLR transformers include remote microcomputer powering applications, industrial power systems, and switched-mode power supplies. Bourns PLR Planar Transformers feature a 250kHz switching frequency, 35VDC to 57VDC transformer input voltage range, and a -40°C to +125°C operating temperature range.
