Temperature compensated 100 pF MLCC claims world first

February 21, 2017 // By Jean-Pierre Joosting
Murata has introduced the first temperature compensated 100 pF 008004 size monolithic ceramic capacitor (MLCC), which is part of the GRM011 capacitor range. With the appearance of a small dot on a piece of paper, it is primarily intended for use in mobile devices and wireless communication modules.

A temperature compensated chip MLCC exhibits little change in capacitance versus temperature variations; hence it is used for matching purposes in filters and high frequency circuits. Component size reduction and higher mounting density are needed in wireless communications devices to support multi-band/multi-mode and an increased diversity of functions.

The GRM011 capacitor range contributes to smaller and higher density circuit designs by reducing the size from the former smallest 0402M size (0.4- x 0.2-mm) to the 0201M size of 0.25-square × 0.125-mm. Alternatively, in EIA coding terms the sizing is 008004.

Presently capacitance values in the range from 11 to 100 pF are available, all featuring a rated voltage of 25 Vdc. For versatility, two tolerance values are available of J (±5%) and G (±2%), and the capacitors feature a useable temperature range of -55 to 125 °C. The capacitors are C0G formulated, it being the most popular formulation of the temperature-compensating EIA Class I ceramic materials.
