New silicon capacitors out-perform MLCCs

8 April 2015 Test & Measurement

In modern high-temperature electronics, where equipment is becoming extremely expensive and where cost of operation is a key driver, a capacitor that cannot fail is desirable, offering high reliability and a long operating lifetime, even at 250°C. To cope with these demands, MLCC technologies involve very high deratings, leaving no room for miniaturisation. Furthermore, these large devices are prone to failures due to ceramic cracks during assembly.

Compared with MLCC, IPDiA MOS technology offers a fully modellised reliability model, which makes its reliability predictable over the lifetime of the application. For example, when a best-in-class MLCC offers a maximum operating lifetime of 1000 hours at 250°C, IPDiA says its Xtreme capacitor range can last up to 84 000 hours under the same conditions. Furthermore, electrical tests after production have proved no susceptibility to early failures.

With its latest technological breakthrough, the company is now able to offer silicon capacitors in values from10 pF to 4,7 μF, with breakdown voltages from 11 V to 450 V, that exceed the overall electrical performance of NPOs or X7Rs thanks to capacitance stability over temperature (60 ppm/°C), voltage and time.
