Package: JST_XH_B4B-XH-A_1x04_P2.50mm_Vertical Library: Connector_JST Category: Connector Pads: 4 Pitch: 2.50mm Body Size: 12.35 x 5.75mm Mounting: Through-Hole

Description

The JST XH series is one of the most widely used wire-to-board connectors in electronics. This 4-pin vertical variant (B4B-XH-A) at 2.50mm pitch provides reliable, locking connections for battery packs, sensor cables, motor wiring, and inter-board communication. The XH series supports up to 3A per contact at 250V, making it suitable for both signal and moderate power applications. Ubiquitous in 3D printers (stepper motors, thermistors), RC/drone battery connections, and maker projects.

Usage Notes

  • Standard through-hole mounting with wave or hand soldering
  • Drill sizes follow IPC-2222 specifications
  • Compatible with standard 2.54mm breadboard pitch
