Common Mode Chokes Procurement Notes

Verify the specific datasheet version from Panasonic Electronic Components before procurement, as specifications may be subject to change without notice. Confirm that the required inductance value of 15mH and DC resistance of 1.8Ω align with your circuit design requirements. Ensure the through-hole package dimensions fit your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Common Mode Chokes Selection Notes

Select this component when a 15mH inductance is required for common mode noise reduction on low-current signal lines up to 400mA. Consider the through-hole mounting style if surface space is limited or mechanical robustness is prioritized. Evaluate the 1.8Ω DC resistance impact on signal voltage drop within your specific application context. Compare against alternative inductance values if higher or lower noise suppression levels are needed.
