FOUNTAIN INN, SC, Sep 3, 2026 – KYOCERA AVX has expanded its KGU series of C0G (NP0) RF multilayer ceramic chip capacitors with an ultraminiature 0201 case size, bringing the line to five EIA chip sizes: 01005, 0201, 0402, 0603, and 0805.
The capacitors are rated from 6.3 to 250 V and 0.1 to 100 pF, with tolerances as low as ±0.05 pF and operating temperatures from -55°C to +125°C.
The series includes:
- Stable Class I dielectric: Class I C0G (NP0) ceramic shows a temperature coefficient of capacitance (TCC) of 0±30 ppm/°C and virtually zero voltage coefficient.
- Base metal electrodes: Tin/nickel-plated copper electrodes provide high electrical conductivity, high capacitance-voltage (CV) capability in tight spaces and good solderability.
- RF characteristics: Ultra-low equivalent series resistance (ESR), high power handling, high Q and high self-resonant frequencies (SRF) limit signal loss and keep precise frequency control.
- Signal integrity: Immunity to aging and microphonics keeps signal performance stable over long operating lifetimes.
- Assembly reliability: Thermal and mechanical resilience lowers the risk of cracking and tombstoning during assembly.
Applications for KGU Series RF MLCCs include bypass, coupling, DC blocking, matching and filter networks, tuning circuits, and high-Q frequency sources. The capacitors are used in subscriber wireless devices, 802.11 Wi-Fi networks, cellular base stations, broadband wireless platforms, satellite communications and public safety radio systems.
KGU Series is RoHS compliant and ships in standard tape-and-reel packaging for high-speed, high-volume automated assembly lines.
“Next-generation RF architectures for satellite communications and high-density wireless networks are challenging design engineers to minimize their physical footprints without compromising signal integrity or power handling,” said Mohammed Abu-Naim, global RF product marketing manager at KYOCERA AVX. “Our new ultraminiature 0201 KGU Series MLCCs are expressly designed to solve this problem. By delivering exceptionally low ESR, high Q, and high repeatability in a submillimeter form factor based on rigorously tested technology backed by years of field-proven performance, the new 0201 KGU MLCCs enable RF engineers to aggressively downsize their designs without risking circuit detuning or manufacturing defects.”
