A161CS12VDC.80

Relay Automotive Overview

The A161CS12VDC.80 is an automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting on printed circuit boards. It features a non-latching coil type with a rated voltage of 12VDC and a maximum switching voltage of 75VDC. The contact arrangement is SPDT (1 Form C), providing one normally open and one normally closed circuit path. The component supports a maximum switching current of 30A at 14VDC and has a contact resistance of less than 30 milliohms initially. It operates within a temperature range of -40°C to 105°C and utilizes AgSnO2 contact material.

Relay Automotive Feature Summary

• SPDT contact configuration enabling simultaneous control of two separate circuits
• High current switching capacity suitable for demanding automotive loads
• Robust construction certified to Micro 280 ISO standards for harsh environments

Relay Automotive Applications

• Automotive lighting systems
• Marine electrical applications
• Lawn care and maintenance equipment

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required contact arrangement and coil specifications. Confirm that the through-hole package dimensions align with the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet version to confirm current manufacturing status and compliance certifications.

Relay Automotive Selection Notes

Select this model when a single pole double throw configuration is required for load switching. The 12VDC coil voltage must match the system supply. Consider the 30A current rating against peak inrush currents of the connected load. Verify that the physical size fits within the available enclosure space compared to alternative series options.

Relay Automotive Part Context

This component belongs to the A16 series of automotive relays from CIT Relay and Switch. The series is characterized by high switching capacity and compact form factors suitable for vehicle electronics. The A161CS variant specifically denotes the SPDT contact arrangement within this product line.

Relay Automotive Replacement Considerations
