# CL31A475KBHNNNE

**Samsung Electro Mechanics** · Global Sourcing Parts · 1206

CL31A475KBHNNNE from Samsung Electro Mechanics, in a 1206. 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 | First end termination (Ni/Sn-plated) of the CL31A475KBHNNNE 4.7µF ±10% 50V X5R MLCC; the capacitor is non-polarized, so either terminal may connect to either net. |
| 2 | 2 | passive | Second end termination (Ni/Sn-plated) of the CL31A475KBHNNNE 4.7µF ±10% 50V X5R MLCC; the capacitor is non-polarized, so either terminal may connect to either net. |

## Materials and finish

As the datasheet states them (page.json `metadata.appearance`; the 3D model's colours follow it).

| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts |  | silver | Since a multilayer ceramic chip capacitor comes into direct contact with melted solder during soldering, it is exposed to potentially mechanical stress caused by the sudden temperature change. The cap | 77 |
