KYOCERA AVX, a global producer of advanced electronic components, has introduced the new KGU Series C0G (NP0) RF multilayer ceramic chip capacitors (MLCCs), designed to meet the evolving needs of the communications sector.
In response to the increasing demand for compact RF capacitors that maintain consistent RF performance, the KGU Series RF MLCCs offer a range of enhanced features suited for communications applications. Available in four compact EIA chip sizes, from 01005 to 0805, the series utilises Class I C0G (NP0) ceramic dielectric materials, renowned for their stability, with a temperature coefficient of capacitance (TCC) of 0±30ppm/°C and negligible voltage coefficient.
The capacitors also incorporate base metal electrodes made from copper, plated with a tin/nickel alloy, delivering high capacitance-voltage (CV) performance within small dimensions. Additional features include ultra-low equivalent series resistance (ESR), high power handling, high Q factor, high self-resonant frequencies (SRF), and precise tolerances, making them ideal for numerous communications applications.
The KGU Series RF MLCCs are available in four miniature EIA chip sizes (01005, 0402, 0603, and 0805) and are rated for 16–250V, with capacitance values ranging from 0.1–100pF, tolerances as tight as ±0.05pF, and operating temperatures between -40°C and +125°C. These capacitors are particularly well-suited for use in filter and matching networks, high-Q frequency sources, and tuning, coupling, bypass, and DC blocking circuits found in cellular base stations, 802.11 Wi-Fi networks, wireless devices, broadband communications, satellite communications, and public safety radio systems.
The KGU Series RF MLCCs also boast additional advantages, such as RoHS compliance, resistance to thermal shock, long-term reliability, no ageing or piezoelectric effects, and packaging in tape and reel format for ease of automated assembly.
“Our new KGU Series C0G (NP0) RF MLCCs provide customers in the communications market with a collection of performance characteristics optimised to satisfy their application demands, including ultra-low ESR, high repeatability, high power, high Q, high SRF, tight tolerances, and miniature EIA chip sizes,” said Mohammed Abu-Naim, RF Product Manager, KYOCERA AVX.
