Overview
The 61304011121 is a 40-position single-row male pin header with a standard 2.54mm (0.100 inch) pitch. Part of the WR-PHD series, this through-hole connector features gold-plated copper alloy contacts and a PA6T nylon housing rated for high-temperature soldering. It is a fundamental component for board-to-board stacking and cable-to-board interfaces in various electronic assemblies.
Why Choose This Part
This header supports a current rating of up to 3A per pin and is constructed from UL94 V-0 rated PA6T material, ensuring reliability in operating temperatures up to 105 degrees Celsius. The gold contact plating provides excellent corrosion resistance and maintains low contact resistance over its 25-cycle mating life.
Applications
Microcontroller Breakouts
Provides a standard interface for connecting development boards like the Arduino Mega or custom MCU PCBs to peripheral modules.
PCB Stacking
Used as a mating interface for female socket headers to create modular, multi-board hardware stacks.
Ribbon Cable Interface
Acts as the board-side termination point for 0.100 inch pitch IDC socket connectors and ribbon cable assemblies.
Prototyping
Commonly soldered into perfboards or stripboards to allow for easy jumper wire connections during the breadboarding phase.
