A101CS12VDC

Relay Automotive Overview

The A101CS12VDC is a through-hole electromechanical relay from the CIT Relay and Switch A10 series, designed for automotive applications. It features a single-pole double-throw (SPDT) contact arrangement with one normally open and one normally closed circuit. The unit operates on a 12VDC coil with a resistance of 254 Ohms and draws 30A on the normally open contacts and 25A on the normally closed contacts. It utilizes PC pin termination for board mounting and functions reliably within an operating temperature range of -40°C to 105°C.

Relay Automotive Feature Summary

• SPDT configuration providing both normally open and normally closed switching paths
• High current capacity supporting up to 30A on the primary contact path
• Through-hole construction with PC pin termination for secure PCB integration

Relay Automotive Applications

• Automotive power distribution systems
• Vehicle control circuits requiring dual-path switching
• Industrial equipment needing high-current relay isolation

Relay Automotive Procurement Notes

Verify that the SPDT contact arrangement aligns with the target circuit design requirements. Confirm that the 254 Ohm coil resistance matches the available drive voltage source capabilities. Ensure the through-hole footprint dimensions are compatible with the printed circuit board layout constraints before finalizing component selection.

Relay Automotive Selection Notes

Select this model when a single relay must manage two distinct load states simultaneously. The 12VDC coil specification suits standard vehicle electrical architectures. Consider the physical dimensions of 12.9x12x9.9mm for spatial planning in dense assemblies. Evaluate the thermal performance limits against expected ambient conditions during continuous operation cycles.

Relay Automotive Part Context

This component belongs to the CIT Relay and Switch A10 series, which focuses on robust automotive-grade relays. The series offers various contact configurations and coil voltages to accommodate diverse vehicle electrical demands. The A101CS12VDC specifically addresses needs for higher current handling in compact through-hole packages.

Relay Automotive Replacement Considerations

Cross-reference part numbers such as A101AS12VDC if a single-pole single-throw configuration is acceptable instead of SPDT. Verify coil resistance values match existing driver circuits to prevent overcurrent issues during replacement.
