Capacitors tolerate high temperatures

The HiCap series is available with capacitance values of up to 100uF in case sizes from 01005 to 1210, with either X7R, X7S or X7U temperature coefficients.

Murata has extended the maximum operating temperature rating of its HiCap series from 85 to 125C.

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.

The HiCap series is available with capacitance values of up to 100uF in case sizes from 01005 to 1210, with either X7R, X7S or X7U temperature coefficients.

Work to expand the range to include all temperature coefficients in all case sizes has already begun, with a 1210 size X7R10uF50V under development as a replacement for tantalum and aluminium electrolytic capacitors.
