ZRB MLCC Capacitors with Interposer Substrate Murata ZRB MLCC Capacitors can replace previous MLCCs without modification by sharing the same footprint. They are designed to reduce noise caused by capacitor vibration via a structure in which the capacitor is mounted in an interposer board. The ZRB series offers a rated voltage range of 4VDC to 35VDC rated voltage and a capacitance range of 2.2µF to 47µF. Typical applications for Murata ZRB MLCC Capacitors include mobile phones, tablet terminals, PCs, car navigation, portable recorders, and much more.
