Overview
The Würth Elektronik 750310035 is a board-mount flyback transformer designed for Power over Ethernet (PoE) applications. It features a single primary winding and supports an input voltage range of 33 V to 57 V, with an auxiliary output of 12 V at 20 mA. The component provides 1500 Vrms isolation and operates at a frequency of 200 kHz. It has a maximum height of 12.70 mm and utilizes surface mount technology.
Feature Summary
- Provides high-voltage isolation of 1500 Vrms for safety compliance in PoE systems.
- Designed specifically for DC/DC converter topologies within Power over Ethernet infrastructure.
- Features a compact surface mount package suitable for space-constrained PCB layouts.
Applications
- Power over Ethernet (PoE) injectors and switches
- DC/DC converter modules for network equipment
- SMPS transformers in industrial networking hardware
Procurement Notes
Verify the specific datasheet revision before procurement, as design corrections have been issued by the manufacturer. Confirm that the required auxiliary voltage specification of 12 V at 20 mA aligns with your circuit design. Ensure compatibility with the LM5022 controller chipset if referenced in your schematic. Check RoHS3 compliance status for regulatory adherence.
Selection Notes
Select this component when designing PoE solutions requiring 1500 Vrms isolation and operation between 33 V and 57 V. It is suitable for applications needing a dedicated auxiliary supply alongside main power conversion. Consider the 200 kHz operating frequency for magnetic component sizing. Evaluate the 12.70 mm height constraint against your mechanical enclosure requirements.
