Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact coil characteristics and contact ratings. Ensure the procurement specification matches the required SPDT configuration and 12VDC coil voltage. Confirm that the sealed, socketable package aligns with the target assembly requirements. Cross-reference the part number with the latest CIT Relay and Switch datasheet to validate active lifecycle status and technical parameters before finalizing orders.

Relay Automotive Selection Notes

Select this component when a non-latching SPDT relay with 12VDC actuation is required for automotive use. The 30A switching capacity suits high-current loads such as lamps or accessories. The integrated diode simplifies circuit design by eliminating external flyback components. Verify that the operating voltage range accommodates the system's minimum must-operate voltage threshold. Consider the socketable form factor if modular replacement or standardized PCB footprint is necessary for the application.
