Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with TE Connectivity or authorized distributors before purchase. Confirm that the component meets the required automotive qualification standards for your specific application environment. Ensure compatibility with your assembly process regarding the 0805 footprint and soldering profile. Check for any recent lifecycle status updates or alternative part recommendations from the manufacturer.

Selection Notes

Select this component when a low-impedance path is required for high-current automotive power lines while maintaining effective high-frequency noise attenuation. The 0805 package offers a compact solution for space-constrained designs. Consider the 3 A current rating and 30 mOhm DCR to ensure minimal voltage drop and power loss in the circuit. Verify thermal performance under maximum load conditions within the specified operating temperature range.
