A3K1ASQ12VDC1.6R

Relay Automotive Overview

The A3K1ASQ12VDC1.6R is an active automotive relay from the A3K series, manufactured by CIT Relay and Switch. It features a non-latching coil with a rated voltage of 12VDC and a coil power consumption of 1.6W. The contact configuration is SPST-NO (Form A), capable of switching up to 80A at 14VDC. Maximum switching voltage reaches 145VDC. Key electrical parameters include a coil resistance of 90 Ohms and a coil current of 133.3 mA. The unit operates within a temperature range of -40°C to 125°C and utilizes AgSnO contact material.

Relay Automotive Feature Summary

• High current switching capacity suitable for demanding automotive loads
• Maxi ISO sized form factor for standardized mounting
• Internal blowout magnets for enhanced arc suppression
• Sealed construction designed for harsh environmental conditions

Relay Automotive Applications

• High-current DC motor control in automotive systems
• Heavy-duty lamp and lighting circuit management
• General purpose high-load switching in vehicle electrical architectures

Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of a built-in resistor or suppressor component as distinct from the base model. Confirm RoHS compliance status and manufacturing origin through official CIT documentation prior to procurement. Ensure the selected variant matches the required coil resistance and contact rating for the target application circuit design.

Relay Automotive Selection Notes

Select this model when an SPST-NO configuration with 80A capacity is required in a Maxi ISO footprint. The 12VDC coil specification suits standard automotive electrical systems. Consider the internal magnet and sealed design for environments requiring robust arc interruption and moisture protection compared to lower-rated alternatives.

Relay Automotive Part Context

This component belongs to the A3K series of automotive relays produced by CIT Relay and Switch. The series is characterized by high current handling capabilities and standardized automotive packaging. The A3K1 variant specifically denotes the SPST-NO contact arrangement within this product line, distinguishing it from SPDT or multi-pole configurations available in the same family.

Relay Automotive Replacement Considerations

Direct substitutes include the A3K1ASQ12VDC1.6D if the resistor/suppressor requirement differs. Verify that replacement parts maintain the 80A contact rating and 145VDC maximum switching voltage. Ensure the physical dimensions and pinout compatibility match the existing PCB or socket layout.
