• General electronic equipment requiring isolated PoE conversion

Procurement Notes

Verify the manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified RoHS compliance status and package type. Check for any recent product change notices or obsolescence announcements from the manufacturer before placing orders. Ensure storage conditions meet the requirements for sensitive surface mount devices.

Selection Notes

Select this component when designing PoE systems requiring a 280 uH primary inductance and 700 mW power handling capability. The 250 kHz operating frequency suits high-density switching converter designs. Verify that the 18 V to 32 V primary input range aligns with the system's power source specifications. Consider the physical footprint constraints given the 8.26 mm by 8.6 mm base dimensions.
