• General-purpose pulse transformation with 2:1 turns ratio
• RoHS3 compliant construction

Applications

• General-purpose signal isolation
• Pulse transmission circuits
• Power supply control interfaces

Procurement Notes

Verify the specific suffix '2C' against official datasheets to confirm through-hole configuration and 500µH inductance. Ensure compatibility with operating temperatures up to 70°C. Check for recent Product Change Notifications or End-of-Life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a 2:1 step-down ratio and 500µH inductance are required for through-hole assembly. Compare ET ratings against circuit requirements to ensure adequate volt-second handling. Verify that the 9.52mm x 9mm footprint fits the target PCB layout constraints.

Part Context
