AZ9841-1C-12DER

Relay Automotive Overview

The AZ9841-1C-12DER is a power/signal relay from the American Zettler AZ9841 series, designed for automotive applications. It features a 12VDC coil with a resistance of 90 Ohms and a current draw of 110.1 mA. The relay utilizes a Single Pole Double Throw (SPDT/1 Form C) contact configuration rated for 40A at a maximum switching voltage of 75VDC. Key electrical parameters include a must-operate voltage of 7.2 VDC and a must-release voltage of 1.2 VDC. It operates within a temperature range of -40°C to 125°C and employs silver tin oxide (AgSnO) contact material.

Relay Automotive Feature Summary

• Features a socketable design compatible with standard automotive relays
• Constructed with an epoxy-sealed housing for environmental protection
• Utilizes Micro-ISO terminal interface for secure connection
• Employs silver tin oxide contacts for high current handling

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• General automotive signal switching

Relay Automotive Procurement Notes

Verify that the specific part number suffix matches the required terminal style and contact rating. Confirm that the supplier provides documentation confirming RoHS compliance and lead-free status as specified by the manufacturer. Ensure the received components are free from physical damage and match the printed specifications on the relay body to guarantee authentic sourcing.

Relay Automotive Selection Notes

Select this component when a 40A SPDT relay is required for 12VDC automotive systems. Consider the 75VDC maximum switching voltage limit for circuit compatibility. Evaluate the need for Micro-ISO terminals and socketable installation. Compare against lower-rated alternatives if the application does not require the full 40A capacity or specific sealing requirements.

Relay Automotive Part Context
