Procurement Notes

Verify the specific inductance value of 1800 µH and the 20 A current rating against your circuit requirements. Confirm the terminal base mounting style matches your PCB or chassis design. Ensure the 250 V AC voltage rating exceeds your system's peak operating voltage. Check that the -25°C to +120°C temperature range covers your environmental conditions.

Selection Notes

Select this component when high current capacity is required alongside significant common mode noise attenuation. The SC-J series offers robust performance for industrial applications. Consider the physical dimensions and weight if space or mechanical load is a constraint. Compare against other SC-J variants if different inductance or current values are needed.

Part Context
