306-036-521-178

Overview

The EDAC 306-036-521-178 is a dual-row card edge connector from the 306 Series, designed for flush mounting applications. It features a contact spacing of 0.156 inches (3.96mm) and accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component utilizes 36 tail-type contacts with gold plating on the contact area to ensure reliable signal transmission. Constructed with a thermoplastic insulator, it supports a maximum operating temperature of +105°C and provides an insulation resistance of 5 GOhms.

Feature Summary

• Dual-row configuration with 36 tail-type contacts for secure PCB connection
• Gold-plated contact areas to enhance conductivity and corrosion resistance
• Thermoplastic insulator body rated for high-temperature environments up to +105°C
• Flush mounting design compatible with standard 0.062-inch nominal thickness PCBs

Applications

• Industrial control systems requiring robust card edge connections
• Communication equipment utilizing high-reliability interconnects
• Medical devices needing stable electrical interfaces in constrained spaces
• Consumer electronics employing flush-mounted circuit board architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact termination style and plating specifications. Ensure the procurement documentation matches the required 306 Series characteristics, including the 0.156-inch spacing and dual-row formation. Cross-reference the lead time information provided by authorized distributors, as manufacturing schedules may vary. Confirm compliance with RoHS3 standards if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a dual-row interface with 36 positions is required for flush-mounting scenarios. The 0.156-inch spacing dictates the trace routing density on the host PCB, so verify board layout compatibility before integration. Consider the +105°C thermal rating for applications involving elevated ambient temperatures or self-heating components. The gold-plated tails offer durability for repeated insertion cycles if applicable to the system design requirements.
