New miniature RF MLCCs for communications applications

Kyocera AVX has released the ultra-low-ESR KGU Series C0G (NP0) RF MLCCs.

Inspired by the growing communications market demand for smaller RF capacitors that produce repeatable RF performance, the new KGU Series RF MLCCs pack multiple performance advantages optimised for communications applications into four miniature EIA chip sizes ranging from 01005 to 0805. The series features Class I C0G (NP0) ceramic dielectric materials, which are one of the most stable capacitor dielectrics available – exhibiting a TCC of 0±30ppm/C and essentially zero voltage coefficient, and base metal electrodes made of copper plated with a tin/nickel alloy, which deliver high CV capabilities in small case sizes. It also exhibits ultra-low ESR, high power, high Q, high SRF, and tight tolerances – all beneficial for countless communications applications.

The series RF MLCCs are currently available in four miniature EIA chip sizes (01005, 0402, 0603, and 0805) and rated for 16–250V, 0.1–100pF, tolerances as low as ±0.05pF, and operating temperatures extending from -40C to +125C. Ideal applications for the series include filter networks, matching networks, high-Q frequency sources, and tuning, coupling, bypass, and DC blocking circuits in cellular base stations, 802.11 Wi-Fi networks, subscriber-based wireless devices, and broadband wireless, satellite communications, and public safety radio systems.

Additional features of the new series MLCCs include RoHS compliance, resistance to thermal shock, long lifetime performance, a lack of ageing and piezoelectric effects, and tape and reel packaging for 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.
