Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official catalog to confirm packaging or variant details, as ordering suffixes may indicate specific configurations. Ensure the required 12VDC coil voltage aligns with system design. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the 120A rating with actual load requirements to ensure adequate safety margins.

Relay Automotive Selection Notes

Select this component when a standard ISO footprint is required alongside high current switching capabilities exceeding typical automotive relays. The 12VDC coil specification suits standard vehicle electrical systems. Consider the internal magnet feature for applications requiring rapid arc extinction. Verify that the SPST-NO configuration matches the circuit logic requirements before procurement.
