0.40mm board-to-board socket DW-BTB-F040100WVnP-XXTR-XX is a fine-pitch female SMT connector designed for compact PCB stacking and signal connection applications. Based on the drawing, this series uses a 0.40mm pitch layout, vertical 180° orientation, and surface-mount termination, making it suitable for electronic assemblies where board space is limited and a low-profile board-to-board interface is required.This 0.40mm board-to-board socket supports 10 to 120 circuit options, including 10, 20, 24, 30, 34, 40, 50, 60, 70, 80, 90, 100, and 120 positions. The product also supports multiple mated height options: 2.00mm, 2.50mm, 3.00mm, 3.50mm, and 4.00mm. These options allow engineers to select the proper board stacking height for different PCB design requirements.
The connector is rated for 0.3A AC/DC current and 30V AC/DC voltage. It provides 500MΩ minimum insulation resistance at 100V DC, 90mΩ maximum contact resistance, and 100V AC dielectric withstand voltage for one minute. The drawing also confirms 30 mating cycles and an operating temperature range from -35°C to +85°C.
The housing material is black LCP rated UL94V-0, and the terminal material is phosphor bronze. Contact plating options include Gold Flash, 5µ” Gold, 10µ” Gold, 15µ” Gold, 30µ” Gold, Sn, or Ni, with nickel underplating. This 0.40mm board-to-board socket is RoHS compliant and suitable for compact electronic products requiring reliable SMT board-to-board connection.
