Higher temperature rating for MLCCs

9 July 2008 Passive Components

Following strong demand from the plasma cell flat panel display and power supply markets, Murata has extended the maximum operating temperature rating of its popular HiCap series from 85°C to 125°C. This has been achieved largely through the development of new ceramic materials.

The primary market for this technology is power supply circuits for plasma cell flat panel displays, where ambient temperature is getting higher due to high power consumption combined with a greater density of components on the PCB. These products are also suitable for general power supplies and other applications that require high operating temperatures.

Murata has developed new ceramic materials which provide high reliability at high ambient temperatures. The HiCap series is available with values up to 100 μF in case sizes from 01005 to 1210, with either X7R, X7S or X7U temperature coefficients, depending on capacitance value.
