Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of the internal diode and exact pin configuration. Ensure the selected variant matches the required coil resistance and contact rating for the target circuit. Cross-reference the datasheet to confirm compliance with automotive environmental standards before finalizing procurement orders.

Relay Automotive Selection Notes

Select this model when an SPDT configuration is required for loads up to 80A. The 48VDC coil specification makes it suitable for heavy-duty vehicle electrical systems. Consider the physical dimensions and through-hole mounting requirements during the mechanical layout phase to ensure proper clearance and thermal management.

Relay Automotive Part Context

This component belongs to the CIT Maxi series of automotive relays, characterized by high current handling capabilities. It is part of a broader family of switches and relays designed for rugged industrial and vehicular use.
