A3KM1CSP12VDC1.6R

Relay Automotive Overview

The A3KM1CSP12VDC1.6R is a non-latching automotive relay from CIT Relay and Switch, designed for high-current applications. It features an SPDT (1 Form C) contact arrangement with a heavy-duty rating of 80A at 14VDC. The coil operates at 12VDC with a resistance of 90 Ohms and consumes 1.6W of power, drawing 133.3 mA. Key electrical specifications include a maximum switching voltage of 75VDC and a maximum switching power of 1120W. Initial contact resistance is less than 30 milliohms, utilizing AgSnO2/In2O3 contact materials.

Relay Automotive Feature Summary

• Supports large switching capacity up to 80A for demanding automotive loads
• Offers flexible mounting options including PCB pins and quick connect terminals
• Manufactured under QS-9000 and ISO-9002 certified quality standards

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• High-current circuit switching in vehicles

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required coil voltage and contact configuration. Confirm that the non-latching coil type matches the system design requirements. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the package style aligns with available PCB footprint or wiring harness connectors.

Relay Automotive Selection Notes

Select this component when an SPDT configuration is required for single-pole double-throw switching operations. The 80A heavy-duty rating makes it suitable for high-power loads compared to standard 40A variants. Consider the 12VDC coil voltage and 1.6W power consumption for driver circuit design. Verify that the physical dimensions and terminal types fit the assembly constraints.

Relay Automotive Part Context

This part belongs to the A3 series of automotive relays from CIT Relay and Switch, characterized by robust construction for vehicle environments. The 'M' designation typically indicates a specific mechanical variant within the series. It complements other models like A3K1CSP12VDC1.6R which shares similar electrical characteristics but may differ in mechanical housing or terminal configuration.

Relay Automotive Replacement Considerations

The A3K1CSP12VDC1.6R is a publicly confirmed substitute part number with matching SPDT form and 80A rating.
