In the world of electronic devices and components,
downsizing is always the way to go. For example, Murata's chip
monolithic ceramic capacitors have become as small as EIA 01005
size (0.4 mm x 0.2 mm). This was only made possible with the
combination of technology to print electrodes that are microns
thick on a dielectric sheet, and technology to laminate those
layers precisely. Downsized components not only contribute to
downsizing devices, but also allow extra freedom in the circuit
design for adding more features and values. Murata also offers
a solution for the increasingly serious problem of mounting
downsized components. |

A chip monolithic ceramic capacitor's footprint
was 3.2 mm x 1.6 mm in 1970. It was reduced to 1.6 mm x 0.8
mm in 1983, 1.0 mm x 0.5 mm in 1990. By 1997, the footprint
shrank rapidly to 0.6 mm x 0.3 mm. In spite of having equal
capacitance, the footprint in 1997 is approximately 1/6 of the
size in 1990. |

Being comprised of 1 µ m dielectric
layers with even and minute crystal grains, chip monolithic
ceramic capacitors are highly reliable. |
