AZ9741-1A-12DE

Relay Automotive Overview

The AZ9741-1A-12DE is a 40 Amp Mini-ISO automotive relay manufactured by American Zettler. It features a 12VDC coil with 90 Ohm resistance and utilizes SPST-NO (Form A) contacts. The component measures 26.5x26.5x24.5 mm and employs through-hole mounting technology.

Relay Automotive Feature Summary

• High current switching capability of up to 40 Amps within a compact form factor
• Available in open, covered, or sealed configurations for diverse environmental needs
• Supports coils up to 24 VDC with small footprint design

Relay Automotive Applications

• Automotive electrical systems
• General purpose switching applications requiring high current capacity

Relay Automotive Procurement Notes

Verify the specific contact configuration matches the required circuit design, as the series includes Form A, B, and C variants. Confirm voltage ratings and coil resistance specifications against system requirements before integration. Ensure compatibility with through-hole assembly processes and check RoHS compliance status if mandated by project standards.

Relay Automotive Selection Notes

Select this model when a 40 Amp switching capacity is necessary within a Mini-ISO package size. Consider the 12VDC coil requirement and SPST-NO contact arrangement. Evaluate space constraints due to the 26.5x26.5x24.5 mm dimensions and verify through-hole mounting suitability for the target PCB layout.
