B4B-XH-A(LF)(SN) Description

Short technical summary and product information.

The JST B4B-XH-A(LF)(SN) is a 4-position, single row, 2.5mm pitch header designed for wire-to-board applications. It features a shrouded 4-wall design with detent lock fastening for secure mating. The header uses square brass pins with tin contact finish and is housed in a natural polyamide (PA66/Nylon 6/6) insulator with UL94 V-0 flammability rating.

 

Electrical ratings include 3A current capacity and 250V voltage rating. The operating temperature range is -25°C to 85°C. The through hole mounting supports both press-fit and solder termination methods, providing flexibility for assembly.

 

This connector is suitable for consumer electronics, industrial controls, and automotive applications where reliable board-to-cable connections are required. The 2.5mm pitch allows for compact PCB layouts while maintaining adequate spacing for signal integrity.
