# B3B-PH-K-S

**JST** · Wire To Board Connector · 插件,P=2mm

B3B-PH-K-S from JST, in a 插件,P=2mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Circuit No.1 contact, which is the end marked 'Circuit No.1' on the through-hole drawing; the datasheet gives no pin-specific function and states connector ratings of 2A AC/DC (AWG #24) and 100V AC/DC. |
| 2 | 2 | passive | Circuit No.2 contact on the 2.0 mm pitch row; the datasheet gives no pin-specific function and states connector ratings of 2A AC/DC (AWG #24) and 100V AC/DC. |
| 3 | 3 | passive | Circuit No.3 contact at the far end of the 2.0 mm pitch row; the datasheet gives no pin-specific function and states connector ratings of 2A AC/DC (AWG #24) and 100V AC/DC. |
