Murata has unveiled the GJM02 series of monolithic ceramic chip capacitors (MLCC) specifically designed for use in high frequency module applications such as for coupling in power amplifiers of cellular phone handsets.
According to the company it is believed to be the world’s first 01005 size (EIA) Hi Q type MLCC. This miniature capacitor measures just 0.4 x 0.2 mm and has both high ‘Q’ and low equivalent serial resistance (ESR) characteristics. Having a high Q value and low ESR is essential for use in VHF, UHF and microwave power amplifier. Together they contribute to improving power amplifier efficiency and lowering power consumption.
The GJM02 is supplied in the new W4PI tape packaging style. Using a 4 mm wide embossed plastic tape with a 1 mm component pitch, this new packaging removes the difficulties associated with using conventional paper tape that can deposit paper dust. Also, product pick-up errors caused by static electricity and component damage due to ESD have been minimised.
