306-018-420-178

Edgeboard Connectors Overview

The EDAC Inc. 306-018-420-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight installation angle. It features 36 positions arranged in a dual-edge configuration, accommodating non-specified cards. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and supports a board thickness range of 0.051 to 0.071 inches (1.30 to 1.80 mm). Termination is achieved via solder tails, and contacts are copper alloy with tin plating. The housing is constructed from thermoplastic polyester, colored green, and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific pin count and plating material against official EDAC datasheets before procurement. Confirm that the dual-edge configuration matches the target PCB design requirements. Ensure the operating temperature range aligns with the intended application environment. Check for any RoHS compliance documentation if required by project specifications. Validate mechanical dimensions against the assembly layout to prevent fitment issues.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 36 positions is required. The 0.156-inch spacing suits applications needing wider pitch connections. Tin plating offers cost-effective conductivity suitable for general-purpose use. Consider the through-hole mounting style for high mechanical stability. Evaluate the -40°C to 105°C range against environmental constraints.
