Relay Automotive Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the required resistor or bracket configuration as per the manufacturer's datasheet. Confirm that the 12VDC coil rating matches the target vehicle's electrical system voltage. Ensure the quick connect terminal style is compatible with existing harness connectors. Check RoHS compliance status if environmental regulations apply to the assembly.

Relay Automotive Selection Notes

Select this model when a compact, high-current SPST solution is required for automotive use. The 40A rating supports heavy loads such as lights, pumps, or fans. The integrated bracket simplifies installation compared to standard relays requiring separate hardware. Verify that the 12VDC coil voltage aligns with the control circuit availability before finalizing the design.

Relay Automotive Part Context

This component belongs to CIT Relay and Switch's automotive relay portfolio, which focuses on reliability in harsh conditions. The series offers various contact configurations and coil voltages to support diverse vehicle architectures.
