The UMK105CG040BV-F Multilayer Ceramic Capacitor, manufactured by Taiyo Yuden, is a subminiature surface-mount electronic component used for a wide variety of applications. It is a MLCC (multilayer ceramic capacitor) type with a size of 0402 (0.4 x 0.2in or 1.0 x 0.50mm). The component is rated at 50 volts DC and has a rated capacitance of 4pF, with a tolerance of 0.1pF, and it is made to C0G (also known as NP0, meaning that it hasis a temperature coefficient of < ±30ppm/K) standards. This piece is suitable for a variety of uses, including but not limited to: filtering, timing, bypassing, and coupling in mobile phones, computers, and other electronic devices.
