A11CSP12VDC1.2R

Relay Automotive Overview

The A11CSP12VDC1.2R is an automotive relay manufactured by CIT Relay and Switch, designed for through-hole PCB mounting. It features a single-pole double-throw (SPDT) contact arrangement with a maximum switching current of 30A at 75VDC. The coil operates on 12VDC, requiring 8.4V to activate and releasing at 1.2VDC. The device functions within a temperature range of -40°C to 85°C and exhibits a release time of 10ms.

Relay Automotive Feature Summary

• SPDT contact configuration provides versatile switching capabilities for automotive circuits
• Robust construction supports high current loads up to 30A in automotive environments
• Through-hole mounting ensures secure PCB integration for vibration resistance

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• General automotive switching applications

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required coil voltage and contact form. Confirm that the SPDT configuration aligns with circuit design requirements. Ensure the 12VDC coil specification is compatible with the vehicle's power supply. Check datasheet revisions for any updates to mechanical dimensions or thermal ratings before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a 12VDC controlled SPDT relay is required for automotive use. Consider the 30A current rating against peak load demands. Evaluate the -40°C to 85°C operating range against environmental conditions. Verify that the through-hole package fits the available PCB space and manufacturing process constraints.

Relay Automotive Part Context

This part belongs to the A11 series of automotive relays from CIT Relay and Switch. The series includes variants with different coil voltages, such as 24VDC options. These relays are generally certified under QS-9000 and ISO-9002 standards, indicating adherence to automotive quality management systems for reliable performance in demanding applications.

Relay Automotive Replacement Considerations

The A11CSP24VDC1.2R serves as a direct functional substitute if the system utilizes a 24VDC coil instead of 12VDC. Both parts share the same SPDT contact form and similar automotive application scope. Verify coil voltage compatibility before substitution.
