Kyocera AVX launches ultra-low-ESR KGU Series MLCCs designed for high-performance communications applications.
Kyocera AVX, United States has introduced the KGU Series C0G (NP0) radio frequency (RF) multilayer ceramic capacitors (MLCC) which is an ultra-low equivalent series resistance (ESR) capacitors developed to meet the growing demand for compact, high-performing RF components in the communications sector. Created specifically for industries relying on robust and repeatable RF performance, these capacitors come in miniature EIA (environmental impact assessments) chip sizes from 01005 to 0805, making them advantageous for applications with strict size constraints. These capacitors serve as essential components for telecommunications engineers, equipment manufacturers, and system designers aiming to improve efficiency and reliability in communication devices.
The KGU Series features Class I C0G (NP0) ceramic dielectric material, known for exceptional stability with a temperature coefficient of capacitance (TCC) of 0±30ppm/C and a near-zero voltage coefficient, ideal for maintaining consistent capacitance in variable conditions. Using copper base metal electrodes with a tin/nickel alloy plating, this series also achieves high capacitance-to-volume (CV) ratios in small chip sizes, which is vital for applications that demand high Q factors, high self-resonant frequency (SRF), and precise tolerance levels.
Rated for voltages from 16V to 250V and capacitance values ranging from 0.1pF to 100pF, the KGU Series capacitors operate in temperatures from -40°C to +125°C, making them suitable for use in critical circuits within cellular base stations, Wi-Fi networks, subscriber devices, and satellite communication systems. Mohammed Abu-Naim, RF product manager , Kyocera AVX, noted, “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.”
These MLCCs also effectively address high frequency and power demands, proving valuable in filter and matching networks, high-Q frequency sources, and essential circuits such as tuning, coupling, bypass, and DC blocking. With RoHS compliance, resistance to thermal shock, no ageing or piezoelectric effects, and packaging suitable for automated assembly, the latest ESR capacitors offer a robust, long-lasting solution for the evolving needs of the communications industry.
