Ideal for EMI/RFI filtering applications
Suitable for energy storage inductors in switching power supplies
High current capability

Applications

EMI/RFI filtering
Energy storage in switching power supplies
Heavy duty hash chokes

Procurement Notes

Verify the specific manufacturer part number against official Hammond Manufacturing documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with your circuit's current requirements and thermal management needs before integration.

Selection Notes

Select this component when high-current handling and effective RF suppression are required in compact switching power supply designs. Evaluate the 1250 µH inductance value against your specific ripple current and frequency requirements to ensure optimal filter performance.

Part Context

This component belongs to the Hammond Manufacturing 1540 series, which specializes in high-current toroid inductors. These parts are distinct from standard signal inductors due to their ability to handle significant DC currents while maintaining stable inductance values under load conditions.

Replacement Considerations

Consult official Hammond Manufacturing cross-reference lists for verified substitutes. Do not assume generic toroid inductors are compatible without verifying inductance, current rating, and lead configuration specifications.
