BM03B-SRSS-TB(LF)(SN) Description

Short technical summary and product information.

The JST BM03B-SRSS-TB(LF)(SN) is a 3-position, single-row, surface mount header with a 1.00mm pitch, designed for board-to-cable/wire connections. This shrouded header features a 4-wall design that protects the male square pins and provides secure push-pull mating with compatible cable connectors.

 

Constructed with copper alloy contacts finished in tin and a natural polyamide (nylon) insulator, this header is rated for 1A at 50V. It operates over a temperature range of -25°C to 85°C and is rated UL94 V-0 for flammability. The solder retention feature helps maintain the component in place during the reflow process.

 

The surface mount termination with solder connection makes this header suitable for automated assembly in compact electronic devices. Its 4.25mm insulation height and 1mm pitch are optimized for space-constrained PCB layouts where reliable wire-to-board interconnects are required.
