FOUNTAIN INN, SC, Feb 24, 2026 – KYOCERA AVX has expanded its 550/560 Series ultra-broadband capacitors to support optical communication systems. The components support high-bandwidth data transmission and add capacitor options for optical hardware design.
The global optical communication systems market is projected to reach $39B by 2034, supported by demand for data transmission across datacenters, cloud platforms, IoT deployments, and 5G networks. As bandwidth needs increase, manufacturers are seeking compact, high-frequency RF/microwave components that maintain signal integrity and reliability, including KYOCERA AVX 550/560 Series capacitors.
KYOCERA AVX 550/560 Series UBCs are multilayer ceramic capacitors (MLCCs) designed for ultra-broadband RF/microwave applications from 7kHz to 110GHz. They offer low insertion loss with a flat response and stable return loss across the band. The parts feature a one-piece construction and are available in three EIA case sizes (01005, 0201, and 0402). Tin- or gold-plated nickel barrier terminations support reflow soldering and help prevent metallization from leaching into the solder, which can create brittle intermetallic compounds, cracking, and solderability issues.
KYOCERA AVX has added four new 550/560 Series UBC part numbers, expanding the lineup to 15 devices. The update introduces four 0402 case capacitance values (1, 10, 22, and 47 nF). It also increases the maximum working voltage to 100V from 16V. The 550/560 Series supports frequencies from 7kHz to 110GHz, with capacitance values ranging from 1–220nF and tolerances of ±10–100%. The capacitors operate at up to 100V across a temperature range of -55°C to +125°C.
The 550/560 Series UBCs support DC blocking, AC coupling, bypass, and feedback functions in microwave and millimeter wave (mmWave) optical communication systems. Their electrical ratings and construction fit transimpedance amplifiers, receive and transmit optical subassemblies (ROSA and TOSA), synchronous optical networks (SONETs), and broadband test equipment. The capacitors are also used in vertical cavity surface emitting lasers (VCSELs), fiber optics, analog and digital front-end circuits, including RF sampling and control designs. Additional applications include 5G and satellite communications networks, along with sensing, imaging, and radar devices used in industrial automation, airport security, concealed weapons detectors, and driverless vehicles.
“KYOCERA AVX has more than 20 years of experience developing advanced RF and microwave components, and we leverage that extensive experience to help customers overcome evolving challenges in a wide range of high-speed, high-bandwidth, and high-frequency applications,” said Mohammed Abu-Naim, RF product manager, KYOCERA AVX – North America. “Our newly expanded selection of 550/560 Series UBCs provides customers with 15 compact, high-frequency RF/microwave capacitors that are built with high-quality materials for high performance repeatability and are lab- and field-tested and -proven to deliver high signal integrity, high reliability, high precision, and ultra-low insertion loss at frequencies up to 110GHz – which many of our competitors can’t match.”
