Temperature compensated MLCC suits portable devices

Murata introduces what is claimed to be the world’s first temperature compensated 100pF 008004 size monolithic ceramic capacitor (MLCC). 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. Meeting this need, the company’s new GRM011 capacitor range contributes to smaller and higher density circuit designs by reducing the size from the former smallest 0402M size (0.4mm x 0.2mm) to the 0201M size of 0.25mm (H & W) × 0.125mm (L). Alternatively, in EIA coding terms the sizing is 008004. Presently capacitance values in the range from 11pF to 100pF are available, all featuring a rated voltage of 25VDC. For versatility, two tolerance values are available of J (±5%) and G (±2%), and the capacitors feature a useable temperature range of -55C to 125C. The capacitors are C0G formulated, it being the most popular formulation of the temperature-compensating EIA Class I ceramic materials.
