Product details

1.20 mm pitch, 3-position, right-angle SMT header

The BM03B-ACHFKS-GACN-ETF is a 3-position, single-row header from JST's ACHF series, built for board-to-cable/wire interconnects. The right-angle SMT orientation places the mating axis parallel to the board — useful when the cable exits along the board edge or inside a tight enclosure. The shrouded 3-wall design protects the male blades from accidental shorting and guides the mating receptacle into alignment. The gold-plated mating surface (Copper Alloy base) keeps contact resistance stable through repeated connect-disconnect cycles — a practical choice for field-serviceable cable assemblies.

Frequently asked questions

What is the mating housing for BM03B-ACHFKS-GACN-ETF?

The BM03B-ACHFKS-GACN-ETF is a male header from the JST ACHF series. It mates with the corresponding ACHF female receptacle housing and crimp terminals. The detent lock on the header engages with the matching latch on the receptacle side. Confirm the exact mating part number from the JST ACHF series documentation for your wire gauge and circuit count.

Is BM03B-ACHFKS-GACN-ETF RoHS compliant?

No, the BM03B-ACHFKS-GACN-ETF is listed as RoHS non-compliant. If your application requires RoHS compliance, consider the BM03B-ACHFKS-GACN-ETF(LF)(SN) variant, which carries a lead-free (LF) suffix — verify its RoHS status separately before ordering.
