A11ASQ12VDC1.2D

Relay Automotive Overview

The A11ASQ12VDC1.2D is a sealed automotive relay from the CIT A1 series, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration rated for 30A at 75VDC maximum. The unit utilizes a 12VDC coil with an integrated protection diode to suppress voltage spikes. Key electrical parameters include a must-operate voltage of 8.4VDC and a must-release voltage of 1.2VDC. Mechanical performance includes an operate time of 10ms and a release time of 7ms. The component is fully sealed, socketable, and compliant with RoHS3 standards.

Relay Automotive Feature Summary

• Fully sealed construction protects internal components from environmental contaminants
• Integrated flyback diode safeguards control circuits from inductive kickback
• Socketable design facilitates easy installation and replacement in vehicle systems

Relay Automotive Applications

• Automotive lighting circuits
• High-current accessory power distribution
• Vehicle safety system actuation

Relay Automotive Procurement Notes

Verify that the specific part number matches the required coil voltage and contact rating for your application. Confirm that the sealed, socketable form factor aligns with your existing harness or PCB layout requirements. Ensure compliance with relevant automotive industry standards and environmental regulations applicable to your region before finalizing procurement decisions.

Relay Automotive Selection Notes

Select this model when a robust, sealed relay is required for 12V automotive environments. The 30A rating suits moderate-to-high current loads, while the 12V coil ensures compatibility with standard vehicle electrical systems. The inclusion of a built-in diode simplifies circuit design by eliminating the need for external suppression components, reducing board space and assembly complexity.

Relay Automotive Part Context

This component belongs to the CIT A1 series of automotive relays, which are engineered for durability in harsh vehicular conditions. The A1 series emphasizes reliability through sealed housings and standardized pin configurations. This specific variant integrates a diode, distinguishing it from non-diode versions within the same family, providing enhanced protection for sensitive control electronics.

Relay Automotive Replacement Considerations

Compatible substitutes include other CIT A1 series relays with matching 12VDC coils and SPST-NO contacts. Verify that alternative parts maintain the 30A current rating and sealed construction. Ensure physical dimensions and terminal layouts are identical to guarantee proper fitment in existing sockets without modification.
