AZ9841-1C-12D

Relay Automotive Overview

The AZ9841-1C-12D is an automotive relay manufactured by American Zettler, featuring a Single Pole Double Throw (SPDT) contact configuration. It operates with a 12VDC coil and supports a switching current of 40A at a maximum voltage of 27VDC. The component utilizes quick connect terminals measuring 0.110 inches (2.8mm) for termination. Designed for robust performance, it functions within an operating temperature range of -40°C to 125°C.

Relay Automotive Feature Summary

• Features a socketable design compatible with standard automotive relay bases.
• Incorporates an internal resistor to suppress voltage spikes during coil de-energization.
• Constructed with epoxy sealing to protect internal components from environmental contaminants.

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle heating and ventilation systems
• General automotive accessory power distribution

Relay Automotive Procurement Notes

Verify the specific contact rating requirement against the datasheet, as some sources indicate 30A while others specify 40A for this series. Confirm terminal pitch compatibility with existing PCB or wiring harness designs. Ensure the application environment stays within the specified -40°C to 125°C operational limits to maintain reliability and prevent premature failure.

Relay Automotive Selection Notes

Select this model when a SPDT configuration is required for switching loads up to 40A in automotive environments. The 12VDC coil voltage aligns with standard vehicle electrical systems. Consider the socketable form factor if ease of replacement is necessary. Verify that the integrated resistor feature meets the circuit's noise suppression requirements without requiring external snubber components.

Relay Automotive Part Context

This component belongs to the AZ9841 series of automotive relays from American Zettler. The series is designed for high-current switching applications in vehicles. The AZ9841-1C-12D specifically denotes the SPDT contact form and 12VDC coil variant. It is part of a broader family of micro-ISO and standard automotive relays offered by the manufacturer.

Relay Automotive Replacement Considerations

Compatible substitutes include the AZ9841-1C-12DR and AZ9841-1C-12DER variants from American Zettler. These alternatives share similar specifications but may differ in packaging or specific manufacturing revisions. Always cross-reference pinouts and mechanical dimensions before substitution.
