Common Mode Chokes Procurement Notes

Verify the specific suffix 'HF' confirms halogen-free status as per manufacturer specifications. Confirm that the 900 mA current rating aligns with your circuit's peak load requirements. Ensure the through-hole package dimensions fit your PCB layout constraints before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when 27 mH inductance is required for common mode noise attenuation. The 900 mA rating suits moderate current applications. Consider the 770 mOhm DCR impact on voltage drop. Verify thermal management capabilities given the -55°C to +130°C operating range for your specific environment.

Common Mode Chokes Part Context

This part belongs to the DCM251515H series from ITG Electronics, Inc., which specializes in magnetic components and EMI filters.
