Relay Automotive Procurement Notes

Verify the specific contact arrangement suffix matches the required SPDT configuration. Confirm coil voltage tolerance aligns with the system's 12VDC supply characteristics. Ensure mounting method compatibility with the target PCB or chassis design. Cross-reference the latest manufacturer datasheet for any updates to dimensional tolerances or material specifications prior to final integration.

Relay Automotive Selection Notes

Select this model when high current handling up to 80A is required within a compact footprint. Consider the SPDT functionality for complex switching logic. Evaluate thermal management requirements given the power dissipation at full load. Compare against alternative CIT series models if different contact arrangements or coil voltages better suit the specific application constraints.

Relay Automotive Part Context
