A3F1CSQ12VDC2

Relay Automotive Overview

The A3F1CSQ12VDC2 is a sealed SPDT automotive relay from CIT Relay and Switch. It features a 12 VDC coil with 80 Ohms resistance and 150 mA current draw. The switch contacts are rated for 80 A at up to 75 VDC, utilizing AgSnOInO material. Designed for chassis mounting with quick connect terminals, it operates within a -40°C to 125°C range. Key timing parameters include 7 ms operation and 5 ms release times.

Relay Automotive Feature Summary

• Sealed construction designed for harsh automotive environments
• High current switching capability of 80 Amperes
• Non-latching coil design for standard control applications

Relay Automotive Applications

• Automotive power distribution systems
• Industrial control circuits requiring high current switching
• Heavy-duty equipment actuation

Relay Automotive Procurement Notes

Verify the specific ordering suffix against official CIT documentation to confirm terminal style and coil specifications. Ensure the requested variant matches the required contact rating and sealing standards for the intended application environment. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Relay Automotive Selection Notes

Select this component when an 80 Ampere switching capacity is required for 12 Volt DC automotive or industrial loads. The sealed design and wide temperature range make it suitable for under-hood or external mounting. Confirm that the quick connect termination style aligns with the existing harness or PCB layout constraints.

Relay Automotive Part Context

This model belongs to the A3F series of automotive relays from CIT Relay and Switch. The series includes various coil voltages and contact configurations. The A3F1CSQ12VDC2 specifically denotes a 12 Volt coil, SPDT configuration, and sealed housing. It is distinct from lower-current variants in the same family.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT models with identical 80A ratings and 12V coils, such as the A3M1CSQ12VDC2, provided pinout and mounting dimensions are compatible. Verify mechanical fit and electrical characteristics before substitution.
