AZ988-1AT-12DSEC3R

Relay Automotive Overview

The AZ988-1AT-12DSEC3R is a Micro-ISO automotive relay manufactured by American Zettler. It features a 12VDC coil with 90 Ohms resistance and 133.3 mA current draw. The switch configuration is SPST (1 Form A) with a 30A rated contact current and 27VDC maximum switching voltage. Contact material is silver tin oxide (AgSnO). Operating temperature ranges from -40°C to 125°C. It utilizes through-hole PCB terminals and includes epoxy sealing.

Relay Automotive Feature Summary

• Micro-ISO form factor designed for automotive applications
• Epoxy sealed construction for environmental protection
• Silver tin oxide contacts for high current handling

Relay Automotive Applications

• Accessory power circuits in vehicles
• Trailer tow light systems
• General automotive load switching

Relay Automotive Procurement Notes

Verify the specific suffix 'SEC3R' against official American Zettler documentation to confirm terminal style and sealing specifications. Ensure the required SPST configuration matches the circuit design, as this model differs from other AZ988 variants with different contact arrangements or coil voltages.

Relay Automotive Selection Notes

Select this component when a 30A single-pole normally open switch is required within a Micro-ISO footprint. The 12VDC coil specification must align with the vehicle's electrical system. Consider the -40°C to 125°C operating range for harsh under-hood environments.

Relay Automotive Part Context

This part belongs to the AZ988 series of Micro-ISO automotive relays. These components are standardized for use in modern vehicle electrical architectures, offering a compact alternative to larger ISO relay formats while maintaining high current capacity.

Relay Automotive Replacement Considerations

Cross-reference with other AZ988 series parts such as AZ988-1CT-12DC1R only if the application permits changing from SPST to SPDT configuration. Verify coil voltage and terminal compatibility before substituting.
