AZ971E-1C-12D

Relay Automotive Overview

The AZ971E-1C-12D is a miniature power relay designed for automotive applications, manufactured by American Zettler. It features an SPDT (1 Form C) contact arrangement with a 12 VDC coil voltage and a nominal coil resistance of 92 Ohms. The device supports a maximum switched current of 30 A for Form C contacts, handling up to 420 W of resistive load at a maximum switched voltage of 150 VDC. It offers high switching capability in a compact European-style footprint, with mechanical life expectancy of 5 x 10^6 operations and electrical life of 1 x 10^5 operations at 40 A. The relay exhibits a typical operate time of 5 ms and release time of 3 ms.

Relay Automotive Feature Summary

• Compact European-style footprint suitable for space-constrained automotive designs
• Robust construction resistant to vibration and shock for reliable operation
• Available in open, covered, or sealed configurations to meet environmental requirements

Relay Automotive Applications

• Automotive power distribution systems
• High in-rush current load control
• Vehicle accessory circuit management

Relay Automotive Procurement Notes

Verify the specific suffix 'D' against the manufacturer's official datasheet to confirm terminal configuration and sealing status. Ensure the 12 VDC coil specification matches the target system voltage. Confirm that the 30 A contact rating aligns with the intended load requirements, noting that special precautions are required if switching voltages exceed 30 VDC.

Relay Automotive Selection Notes

Select this model when a compact SPDT relay is required for automotive environments. Consider the 12 VDC coil voltage compatibility and the 30 A current limit for Form C contacts. Evaluate the need for sealed versus open versions based on exposure to moisture or dust. Verify that the small footprint fits within the designated PCB area constraints.

Relay Automotive Part Context

This component belongs to the AZ971E series of miniature power relays from American Zettler. The series is characterized by its ability to handle up to 40 Amps in a small form factor, catering specifically to automotive and industrial applications requiring reliable switching in tight spaces.

Relay Automotive Replacement Considerations

Cross-reference with other AZ971E variants such as AZ971E-1A-12DE or AZ971E-1C-24D for different contact forms or coil voltages. Ensure any substitute maintains the SPDT configuration and compatible coil specifications.
