345-140-544-508

Edgeboard Connectors Overview

The EDAC Inc. model 345-140-544-508 is a standard card edge connector featuring 140 positions with a 2.54 mm (0.100 inch) pitch. Designed for dual-edge board insertion, it utilizes female contacts plated with gold to ensure reliable signal transmission. The component supports through-hole mounting and wire wrap termination methods. It accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB thickness limits and mounting hole dimensions before finalizing procurement orders to prevent integration failures.

Edgeboard Connectors Selection Notes

Select this component when high-density dual-edge connectivity is required with wire wrap termination capabilities. Confirm that the operating temperature range of -40°C to 105°C aligns with the environmental conditions of the intended application. Validate that the 3A current rating per contact meets the electrical load requirements of the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and termination options. The 345-140 variant specifically addresses applications requiring higher I/O density compared to lower-position counterparts within the same family line.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 345 series parts sharing identical pitch and termination style. Verify mechanical footprint and electrical ratings match exactly before substituting.
