Common Mode Chokes Procurement Notes

Verify the specific suffix HR against official TDK documentation to confirm material composition and thermal characteristics. Ensure the procurement channel provides valid traceability records. Confirm that the delivered components match the AEC-Q200 qualification status specified in the datasheet. Check for any updates to the RoHS compliance status prior to finalizing orders.

Common Mode Chokes Selection Notes

Select this component when high impedance is required for signal lines in space-constrained automotive applications. The 100 mA rated current limits suitability for power lines; verify load requirements against this limit. The wide operating temperature range supports harsh environments. Compare physical dimensions against board space constraints before integration.
