Monolithic Ceramic Capacitor features interposer substrate.

Press Release Summary:

Comprising 22 µF 6.3 WV values with X5R temperature rating in both 0804 and 0906 formats, ZRA Series is specifically designed to absorb mechanical vibration generated within capacitor, typically sounding as squealing, when voltage is applied to it. Tests conducted indicate as much as 20 dB reduction in audio noise measured at 3 kHz when compared against traditionally constructed MLCC. Series is suited for power supply circuits used in laptops, smartphones, and digital cameras.

Original Press Release:

Murata Launches World's First MLCC on Interposer Substrate

Hoofddorp, Netherlands: Murata today announced mass production of the first monolithic ceramic capacitor (MLCC) on a interposer substrate. Believed to be the world’s first MLCC to have this construction technique, the ZRA series has been designed specifically to absorb mechanical vibration generated within the capacitor, typically sounding as “squealing”, when a voltage is applied to it.

“Squealing” has become an industry issue especially in the design of power supply circuits of consumer applications such as laptops, smartphones and digital cameras. The PCB can amplify the audio noise generated by the capacitor, so by using an interposer substrate the MLCC becomes mechanically isolated from the PCB. Tests conducted by Murata have indicated as much as a 20 dB reduction in audio noise measured at 3 kHz when compared against a traditionally constructed MLCC.

The ZRA series currently comprises 22 uF 6.3 WV values with X5R temperature rating in both 0804 and 0906 formats. More capacitance values, in the range 1 to 22 uF, will be added shortly.
