Relay Automotive Procurement Notes

Verify the specific suffix 'D' against manufacturer documentation to confirm terminal style and internal circuitry variations. Ensure the operating environment aligns with the component's thermal ratings. Cross-reference the coil resistance value with the system's driver capabilities to prevent overloading. Confirm that the quick-connect termination type matches the existing harness connectors. Validate RoHS compliance status if required by project specifications.

Relay Automotive Selection Notes

Select this model when a high-current SPST-NO switch is required for 12VDC automotive circuits. The 80A rating exceeds standard low-power relay capabilities, making it suitable for heavy loads. Consider the through-hole mounting requirement during PCB or panel design. Evaluate the 22.5-ohm coil resistance against available drive voltages to ensure reliable actuation without excessive current draw from the control source.
