A2H1CSQ12VDC1.6D

Relay Automotive Overview

The A2H1CSQ12VDC1.6D is a sealed SPDT automotive relay from the CIT A2 series, designed for high-current switching applications. It features a 12VDC coil with a rated power of 1.6W and a resistance of 90 Ohms. The contact configuration is Form C (SPDT), providing one normally open and one normally closed circuit. The unit supports quick connect termination and base mounting, ensuring secure installation in vehicle electrical systems.

Relay Automotive Feature Summary

• Fully sealed construction protects internal components from environmental contaminants
• Integrated flyback diode safeguards control circuits from voltage spikes
• High current capacity suitable for demanding automotive loads
• Quick connect terminals facilitate rapid assembly and maintenance

Relay Automotive Applications

• Automotive lighting control systems
• Vehicle accessory power distribution
• Industrial equipment switching
• General purpose high-current relay applications

Relay Automotive Procurement Notes

Verify that the specific part number includes the integrated diode suffix 'D' if transient suppression is required for the application. Confirm that the operating environment temperature range aligns with the component's specified limits. Ensure the mounting base is compatible with the quick connect pin dimensions to guarantee proper electrical connection and mechanical stability during operation.

Relay Automotive Selection Notes

Select this model when a single pole double throw configuration is necessary for switching between two different circuits or loads. The sealed design makes it appropriate for harsh environments where moisture or dust exposure is likely. Consider the 40A switching capacity against the maximum load requirements to ensure adequate safety margins for continuous operation under varying thermal conditions.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, which are characterized by compact dimensions and robust performance standards. The series is widely utilized in transportation sectors due to its reliability and compliance with industry certifications. The A2H1CSQ12VDC1.6D variant specifically addresses applications requiring SPDT functionality with built-in protection features.

Relay Automotive Replacement Considerations

Compatible substitutes include the A2S1ASQ12VDC1.6 for SPST configurations and the A2M1USP12VDC1.6 for switch-based alternatives. Verify that any replacement maintains the same coil voltage and contact rating specifications to ensure system compatibility without modification.
