Procurement Notes

Verify the specific rated temperature class (+40 °C through +70 °C) required for your application against the datasheet specifications. Confirm that the 4.8 A current rating aligns with your circuit's peak load requirements. Ensure compatibility with the 250 V AC rated voltage and 1500 V AC test voltage standards. Check for RoHS compliance status if mandated by your regional regulations.

Selection Notes

Select this component when high current capacity is needed alongside effective common mode noise attenuation. The radial leaded package facilitates through-hole mounting on printed circuit boards. Consider the physical dimensions and thermal dissipation characteristics relative to the enclosure space. Evaluate the trade-off between inductance value and DC resistance for optimal filter performance in your specific power stage.
