Common Mode Chokes Procurement Notes

Verify the specific inductance value required, as the datasheet indicates a broad range (18000 to 500 microHenries). Confirm that the 3A current rating and 52mOhm resistance align with circuit requirements. Ensure the operating temperature range of -55°C to +155°C meets environmental conditions. Check for RoHS compliance status if mandated by project specifications.

Common Mode Chokes Selection Notes

Select this component when high-temperature stability up to 155°C is necessary. The 3A current capacity suits moderate power applications requiring common mode noise attenuation. Verify physical dimensions against PCB layout constraints. Consider the through-hole technology requirement versus surface-mount alternatives if space or assembly methods differ.
