KYOCERA AVX Debuts 0201 KGU Series RF MLCCs

KYOCERA AVX has expanded its field-proven KGU Series of high-performance, ultra-low-ESR C0G (NP0) RF multilayer ceramic chip capacitors (MLCCs) by adding a new ultraminiature 0201 case size. Engineered to meet the rigorous footprint and reliability demands of the communications industry, these compact components provide highly repeatable RF performance for satellite networks, cellular base stations, and broadband wireless platforms.

The KGU Series is now available in five EIA chip sizes—01005, 0201, 0402, 0603, and 0805. The capacitors feature extremely stable Class I C0G ceramic dielectrics with a temperature coefficient of capacitance (TCC) of 0±30ppm/°C and virtually zero voltage coefficient.

Designed with tin/nickel-plated copper base metal electrodes, they offer high electrical conductivity and robust solderability. Rated for 6.3–250V and 0.1–100pF, the MLCCs operate effectively in temperatures ranging from -55°C to +125°C. Their inherent immunity to aging and microphonics, combined with high thermal and mechanical resilience, eliminates assembly risks such as cracking and tombstoning, helping OEMs maximize production yields on high-speed automated lines.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

As next-generation RF architectures—such as 5G Advanced, Wi-Fi 7, and low-Earth orbit (LEO) satellite arrays—push toward higher frequencies and denser board layouts, engineers face intense pressure to shrink physical footprints without compromising signal integrity or power handling. High-frequency circuits depend heavily on capacitors with ultra-low Equivalent Series Resistance (ESR) and a high Quality Factor (Q) to prevent power dissipation, minimize thermal buildup, and maintain precise tuning. Standard capacitors often suffer from piezoelectric noise (microphonics) or capacitance drift due to temperature fluctuations, which can quickly detune sensitive RF filters and impedance matching networks. By utilizing a highly stable C0G (NP0) dielectric within a submillimeter EIA 0201 form factor (0.6mm x 0.3mm), these MLCCs enable developers to aggressively downsize RF amplifiers and frequency sources while ensuring clean, reliable signal transmission over long lifespans.
