Compact, with the largest capacity for its size!

Murata GCM31CC71E106KA03 GCM31CC71H475KA03

Murata Manufacturing Co., Ltd. has reduced the size and increased the capacity of its GCM series of chip monolithic capacitors for automotive applications.

By developing new materials, Murata successfully reduced the size from the 3225 size (3.2mm × 2.5mm) mainly used thus far to the 3216 size (3.2mm × 1.6mm) , while at the same time expanding the capacitance from 2.2µF to 4.7µF (rated voltage 50 V type) and from 4.7µF to 10µF (rated voltage 25 V type) . The realization of 4.7 µF in a rated voltage 50 V type capacitor is a world first, and is the largest capacity in the world for its size.

Aluminum electrolytic capacitors and tantalum capacitors have been used in automotive power supply circuits thus far, but these can now be replaced with GCM series products.

Background

Large-capacitance capacitors are required for smoothing applications in automotive power supply circuits, so aluminum electrolytic capacitors and tantalum capacitors are often used. However, ceramic capacitors that are resistant to high temperatures are more suitable for automotive applications that require heat resistance. Therefore, by increasing the capacitance, GCM series products can now be used in place of the aluminum electrolytic capacitors and tantalum capacitors used thus far.

In addition, as the electrification of automobiles progresses, the number of electronic components used is also increasing, and miniaturization is demanded. Thus far, 3225 size products have mainly been used for these applications, but the development of new materials has allowed us to realize a size reduction to 3216 size.
