345-144-541-807

Edgeboard Connectors Overview

The EDAC Inc. 345-144-541-807 is a dual-edge female card edge connector designed for board-to-board or backplane interconnections. It features 144 positions with a 0.100-inch (2.54mm) pitch arranged in two rows of 72 contacts each. The connector utilizes gold-plated cantilever spring contacts housed in a green thermoplastic polyester insulator, providing reliable signal transmission. It supports PCB thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration ensures secure mating with non-specified double-sided edge cards.
• Gold-plated cantilever spring contacts provide durable electrical connection and low contact resistance.
• Thermoplastic polyester insulation offers thermal stability and mechanical strength for harsh environments.

Edgeboard Connectors Applications

• Industrial control systems requiring robust backplane connectivity
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact plating thickness and flange specifications. Ensure compatibility with target PCB thickness limits before procurement. Cross-reference the RoHS status and environmental compliance data with the latest official documentation to meet regulatory requirements for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a high-density 144-position interface is required with a standard 2.54mm pitch. Confirm that the application environment stays within the specified -40°C to 105°C operating range. Validate that the host PCB thickness falls between 0.054 and 0.070 inches to ensure proper mechanical retention and electrical contact integrity during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series is characterized by through-hole mounting options and wire wrap termination styles. It serves as a critical interconnect solution for modular electronic designs, offering a balance of density and mechanical reliability for industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 345 series variants with matching pin counts and pitch, such as the 345-144-541-588, provided the flange and termination specifications align with the design requirements.
