Frequently Asked Questions
What current and voltage ratings does the BM03B-SRSS-TB(LFSN) JST SH connector support?
The BM03B-SRSS-TB(LFSN) is rated at 1A per contact with the JST SH series operating at up to 50V AC/DC. Its 3-position 1 mm pitch layout handles both power and signal lines in compact PCB designs for wearables, IoT modules, and portable consumer electronics requiring a low-profile surface mount board header.
Which compact product designs most benefit from the BM03B-SRSS-TB(LFSN) as a board connector?
Wearable fitness trackers, consumer drones, IoT sensor nodes, and miniature robotics benefit most from this connector's 1 mm pitch 3-position layout, which permits battery, power, and data connections on very small PCBs. Its 1A rating and SMT solder termination suit single-cell lithium battery systems and low-power sensing modules where board area is at a premium.
How does the BM03B-SRSS-TB(LFSN) 1 mm pitch compare to JST PH or GH series options for miniaturized designs?
The BM03B-SRSS-TB(LFSN) uses 1 mm pitch, compared to 2 mm for the PH series and 1.25 mm for the GH series, making the SH series the most compact choice among common JST headers. All variants support 1A per contact, but the SH series 1 mm pitch is preferred for the smallest IoT wearables and drone ESC boards where minimizing PCB footprint is critical.
