CONN HEADER 8POS 2.54mm DUAL ROW SMD The 2.54-2×4P is a generic 8-pin dual-row connector/header with a 2.54 mm (0.1 inch) pitch, commonly used for board-to-board, wire-to-board, and programming/debug interfaces in electronic circuits. The designation 2×4P indicates two rows of four pins, providing a total of eight electrical connections in a compact arrangement. This type of connector is widely used in embedded systems, development boards, industrial control equipment, consumer electronics, and prototyping applications due to its standard pitch and broad compatibility with jumper wires, IDC cables, and mating sockets. Key Features 2.54 mm standard pitch (0.1 inch industry standard) 2×4 pin configuration (8 total contacts) Available in through-hole (THT) and sometimes surface-mount (SMT) versions Supports board-to-board and wire-to-board connections Compatible with standard jumper wires and ribbon cable connectors Compact dual-row design for higher pin density Typically constructed with gold-plated or tin-plated contacts for reliable electrical performance Suitable for signal, control, and low-power applications Commonly used for programming, debugging, communication interfaces, and expansion headers Available in straight (vertical) or right-angle orientations depending on manufacturer Typical Applications Microcontroller and development boards ISP/JTAG/SWD programming headers Sensor and peripheral connections Industrial control systems Prototyping and breadboard-compatible designs Communication interfaces and expansion ports #CommonPartsLibrary #Connector

Connector Header Surface Mount, Right Angle 4 position 0.039" (1.00mm) The SM04B-SRSS-TB (LF)(SN) is a JST SH/SR series 4-position wire-to-board connector header designed for compact, high-density PCB applications. It features a 1.0 mm pitch, right-angle surface-mount (SMT) design, and a shrouded housing for secure mating and alignment. This connector is commonly used in space-constrained electronic devices where reliable signal transmission and low-profile mounting are required, such as in consumer electronics, industrial control boards, and embedded systems. It mates with compatible JST SH series housings, providing a secure push-fit connection for crimped wire assemblies. Key Features 4-position (1x4) wire-to-board connector header 1.0 mm fine pitch for compact PCB layouts Surface-mount (SMT), right-angle configuration Shrouded design for improved alignment and protection Rated current: 1 A per contact Rated voltage: 50 V AC/DC Low-profile height (~2.9 mm) Tin-plated contacts for reliable conductivity Operating temperature: -25°C to +85°C Compatible with JST SH/SR series mating housings Tape-and-reel packaging for automated PCB assembly #CommonPartsLibrary #Connector #JST #SM04BSRSSTB #SHSeries #SRSeries #WireToBoard #1mmPitch #SMTConnector #PCBConnector #ElectronicsComponents #ConnectorHeader

Micro-Fit 3.0 Vertical Header, 3.00mm Pitch, Dual Row, 4 Circuits, with PCB Press-fit Metal Retention Clip Connector Header Through Hole 4 position 0.118" (3.00mm) The Molex 0430450426 is a 4-position vertical PCB header belonging to the Micro-Fit 3.0 series, designed for compact and reliable power and signal wire-to-board connections. It features a 3.00 mm pitch, through-hole mounting, and a shrouded design for secure mating with compatible receptacles. This connector is commonly used in applications requiring medium-current power delivery in a compact footprint, such as industrial equipment, automotive electronics, consumer devices, and telecommunications systems. It supports a robust locking mechanism to prevent accidental disengagement and ensures stable electrical performance in vibration-prone environments.
