What are the key electrical ratings?

The connector is rated for 1.0 A current and 50 V AC/DC voltage.

What is the operating temperature range?

It operates between -40°C and +105°C, which includes the temperature rise during current application.

What should be reviewed before use?

Engineers should review the PCB layout, ensure the correct crimp contacts (SSHL-002T-P0.2) are used, and check the handling precautions for terminals and connectors on the JST website.

What should sourcing teams check before buying BM03B-GHS-TBT(LF)(SN)?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of BM03B-GHS-TBT(LF)(SN)?

Use the BM03B-GHS-TBT(LF)(SN) datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about BM03B-GHS-TBT(LF)(SN) pinout to locate pins, power rails, and interface signals before layout.
