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
