AZ970E-1C-12D

Relay Automotive Overview

The AZ970E-1C-12D is a 45 Amp automotive relay manufactured by American Zettler. It features a SPDT (1 Form C) contact arrangement with a maximum switched voltage of 75 VDC. The coil operates at 12 VDC with a resistance of 90 Ohms. Key electrical parameters include a contact resistance of 100 mOhms and a dielectric strength of 500 VDC between coil and contacts. The device offers mechanical life expectancy of 5 x 10^6 operations and electrical life of 1 x 10^5 operations at rated load.

Relay Automotive Feature Summary

• Compact footprint design suitable for space-constrained automotive applications
• High current switching capability up to 45 Amps in a small package
• Robust construction resistant to vibration and shock
• Available in open, covered, or sealed configurations

Relay Automotive Applications

• Automotive power distribution systems
• High-current circuit protection and switching
• Industrial control panels requiring compact relays
• Battery management systems in electric vehicles

Relay Automotive Procurement Notes

Verify the specific suffix 'E' indicates the enhanced or sealed variant compared to standard AZ970 models. Confirm coil voltage tolerance matches the 12VDC nominal requirement. Ensure the SPDT configuration aligns with circuit logic needs. Check for RoHS compliance if required by project specifications. Validate packaging quantity against distributor standards.

Relay Automotive Selection Notes

Select this model when high current capacity exceeds standard 30A relays but board space is limited. The SPDT configuration allows for complex switching logic within a single component. Consider the 75VDC rating for compatibility with higher voltage automotive networks. Evaluate thermal management requirements given the 45A continuous rating. Compare against AZ970 series alternatives for cost-performance balance.

Relay Automotive Part Context

Part of the American Zettler AZ970 series of miniature automotive relays. Designed specifically for high-current applications in modern vehicles. Competes with other compact automotive relay families offering similar form factors. Represents an evolution in high-density power switching solutions for OEMs.

Relay Automotive Replacement Considerations

Direct substitutes may include AZ970-1C-12D or AZ970E-1C-12D variants from American Zettler. Verify pinout compatibility before substitution. Cross-reference with AZ971 series for similar performance in different contact arrangements. Ensure coil voltage and current ratings match existing circuit designs.
