837-022-500-103

Edgeboard Connectors Overview

The EDAC Inc. 837-022-500-103 is a standard card edge connector from the High Temp Series, designed for high-temperature environments. It features 22 positions with a 3.96 mm (0.156 inch) contact spacing in a single row configuration. The receptacle utilizes gold-plated copper alloy contacts and a green diallyl phthalate (DAP) insulator. Rated for 3 A current, it supports through-hole installation with wire wrap termination. Operating temperatures range from -40°C to +125°C, accommodating PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• High-temperature resistant DAP insulator construction
• Gold-plated copper alloy contacts for reliable signal transmission
• Single-row receptacle design with wire wrap termination
• Through-hole mounting for secure board integration

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• Automotive electronics operating in high heat zones
• Communication equipment with strict temperature tolerances
• Military and aerospace circuit boards

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to ensure correct termination style and plating specifications. Confirm that the supplier provides original manufacturer documentation or datasheets matching the 837 series standards. Check compatibility with target PCB thickness ranges before ordering. Ensure storage conditions maintain integrity of the thermoset insulator material.

Edgeboard Connectors Selection Notes

Select this component when a single-row connection is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch suits applications needing robust mechanical retention. Choose this model over lower-temperature variants if operating environments exceed standard limits. Verify that wire wrap termination aligns with assembly processes rather than surface mount alternatives.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 837 High Temp Series, characterized by durable materials for harsh conditions. The series offers various position counts and termination options. The 837-022 variant specifically addresses mid-range density needs in single-row configurations. It complements other EDAC solutions for comprehensive board-to-board connectivity.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 837-022-500-203 for dual-edge gold variations. Check 837-022-523-858 for double-row tail-type contacts if higher density is needed. Ensure substitute parts match the 3.96 mm pitch and DAP insulator material properties.
