Product details

1.20 mm Pitch, 3-Position Right-Angle SMT Header

The BM03B-ACHFKS-GACN-ETF(LF)(SN): Its 1.20 mm pitch sets a compact footprint — tighter than the common 2.54 mm headers — so the PCB layout needs to confirm pad spacing and trace escape routing before committing.

2.5 A per Contact, 50 V Rating

Each contact is rated at 2.5 A and 50 V — moderate current for signal-level loads, but the 1.20 mm pitch limits the cross-section of the PCB traces that feed the header. For bundles of multiple circuits, derate the per-contact current to stay within the temperature rise limits of the housing material.

Frequently asked questions

Where can I buy JST BM03B-ACHFKS-GACN-ETF(LF)(SN) and how do I get a price?

The BM03B-ACHFKS-GACN-ETF(LF)(SN) is an active part available through independent distribution. Submit an RFQ with your target quantity and we will confirm current pricing and lead time — no stock-holding claim, sourced per order.

What is the pinout of BM03B-ACHFKS-GACN-ETF(LF)(SN)?

The pinout is a single row of 3 positions, all loaded, with male blade contacts. The mating interface is keyed by the shrouded housing and detent lock — the receptacle side determines the circuit assignment.

What is the difference between BM03B-ACHFKS and BM03B-ACHFKC?

The evidence does not list a BM03B-ACHFKC variant.

Is BM03B-ACHFKS-GACN-ETF(LF)(SN) compatible with wire AWG 22?

The evidence does not specify the wire gauge range for the mating receptacle. The header itself accepts the male blade contacts; wire compatibility depends on the crimp terminal used in the mating half.
