Procurement Notes

Verify the specific AEC-Q200 qualification status directly with the manufacturer or authorized distributors, as this certification is critical for automotive compliance. Confirm that the 1 kOhm impedance value aligns with your circuit's noise filtering requirements at the target frequency. Ensure the 230 mA current rating meets the operational demands of the protected lines without saturation.

Selection Notes

Select this component when space-constrained automotive designs require robust common mode rejection for data lines. The wide operating temperature range makes it suitable for harsh under-hood environments. Compare its 1 Ohm DCR against other options to minimize voltage drop in sensitive signal paths while maintaining the necessary 1 kOhm impedance profile.
