AZ988-1CT-12DC1

Relay Automotive Overview

The AZ988-1CT-12DC1 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 contacts are SPDT (1 Form C) rated for 30A at 27VDC maximum. Key electrical parameters include a 7.2VDC pull-in voltage, 1.2VDC drop-out voltage, and 1.6W coil power. Mechanical operation times are 10 ms for both make and break. The unit utilizes silver tin oxide contacts and offers epoxy sealing for environmental protection.

Relay Automotive Feature Summary

• Micro-ISO form factor designed for standard automotive blade fuse box integration
• Epoxy sealed construction provides environmental protection against moisture and contaminants
• SPDT contact configuration allows switching between common, normally open, and normally closed circuits

Relay Automotive Applications

• Automotive lighting systems including headlights and interior illumination
• High-current accessory control such as cooling fans and fuel pumps
• Power distribution management in vehicle electrical architectures

Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm if it denotes a specific tape-and-reel packaging variant or a minor material difference compared to the base part number. Ensure compatibility with existing Micro-ISO sockets and validate that the 12VDC coil specification matches the target vehicle's electrical system requirements before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a single-pole double-throw switching capability is required within a compact Micro-ISO footprint. The 30A rating supports high-load applications, while the 12VDC coil ensures compatibility with standard automotive battery voltages. Consider the 10 ms operating speed and epoxy sealing for environments requiring rapid response and robust environmental resistance.

Relay Automotive Part Context

This relay belongs to the AZ988 series of automotive relays from American Zettler. The series is characterized by its adherence to Micro-ISO standards, ensuring interchangeability with other manufacturers' components in the same form factor. The AZ988 line is widely utilized in modern vehicle designs for reliable power switching in demanding thermal and vibrational conditions.

Relay Automotive Replacement Considerations

Cross-reference with other Micro-ISO SPDT 12VDC 30A relays from different manufacturers. Verify pinout compatibility and physical dimensions to ensure direct socket fitment without adapter requirements.
