A3F1ASQ12VDC2D

Relay Automotive Overview

The A3F1ASQ12VDC2D is a sealed automotive relay from the CIT Relay and Switch A3F series, designed for high-current switching applications. It features a non-latching coil operating at 12VDC with a current draw of 150 mA and power consumption of 1.8W. The unit utilizes an SPST-NO (Form A) contact arrangement capable of handling up to 80A at 14VDC in heavy-duty configurations. Key electrical specifications include a maximum switching voltage of 75VDC, maximum switching power of 1120W, and initial contact resistance below 30 milliohms. The contacts are composed of AgSnO2/In2O3 materials.

Relay Automotive Feature Summary

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct coil voltage, contact form, and mounting style. Confirm that the required base or socket compatibility matches the chassis mount design. Check for RoHS compliance status if environmental regulations apply to your assembly. Ensure the selected variant includes the necessary integral components such as the suppression diode.

Relay Automotive Selection Notes

Select this component when a single-pole normally-open configuration is required for high-amperage DC circuits. The 12VDC coil specification aligns with standard automotive electrical systems. Consider the physical dimensions and flange mount requirements for enclosure integration. Evaluate the 80A heavy-duty rating against peak load currents to ensure adequate safety margins during operation.
