Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct coil voltage and contact configuration. Confirm that the required package type matches the intended PCB layout or panel mount requirements. Check for any specific environmental certifications such as REACH or RoHS compliance relevant to your region. Ensure the operating temperature range meets the thermal conditions of the final assembly environment before procurement.

Relay Automotive Selection Notes

Select this component when a 24VDC coil voltage is required for automotive circuits. The SPST-NO configuration suits simple on/off control loads up to 30A. Consider the 5ms operate time for applications requiring moderate switching speed. Verify that the through-hole PC pin termination is compatible with the manufacturing process. Evaluate the 75VDC maximum switching voltage against the load requirements to ensure safe operation margins.
