KYOCERA AVX Expands Ultra-Broadband Capacitors Lineup to Meet Surging Optical Communication Demand
The company is responding to booming demand for high-speed optical communication systems by expanding its popular 550/560 Series ultra-broadband capacitors (UBCs).
These high-frequency RF/microwave components deliver the signal integrity, reliability, and precision that today’s optical systems demand.
Engineered as multilayer ceramic capacitors (MLCCs), the 550/560 Series provides consistent ultra-broadband performance from 7kHz to 110GHz with ultra-low insertion loss, flat frequency response, and excellent return loss.
Rugged design for demanding applications
The series features rugged, one-piece construction in three EIA case sizes (01005, 0201, 0402) and comes with tin-or-gold-plated nickel barrier terminations.
These terminations are specifically designed for reflow soldering and prevent base metallization from leaching into the solder eliminating the risk of brittle intermetallic compounds that can cause cracking or solderability issues.
Expanded specifications for broader applications
The latest expansion adds four new part numbers, bringing the total to 15 options.
Key enhancements include:
- Four new 0402 case capacitance values: 1nF, 10nF, 22nF, and 47nF
- Extended maximum working voltage: up to 100V (previously 16V)
- Frequency range: 7kHz to 110GHz
- Capacitance values: 1–220nF (±10–100% tolerance)
- Operating temperature: -55°C to +125°C
Perfect for next-gen optical and RF systems
With these robust ratings and superior performance, 550/560 Series UBCs excel in DC blocking, AC coupling, bypassing, and feedback applications across high-speed microwave and mmWave optical communication systems.
Popular Applications Include:
- Transimpedance amplifiers
- Receive and transmit optical subassemblies (ROSA, TOSA)
- Synchronous optical networks (SONET)
- Broadband test equipment
- VCSELs and fiber optics
- Analog/digital front-end circuits
- 5G and satellite communications
- High-resolution sensing, imaging, radar (from industrial automation to airport security, concealed weapons detection, and autonomous vehicles)
This expansion positions the 550/560 Series as a go-to solution for engineers designing the high-bandwidth optical infrastructure powering tomorrow’s connected world.
The global optical communication systems market is currently valued at $38.99 billion and is projected to be worth $38.99 billion by 2034 due, in large part, to the widespread proliferation of high-speed, high-bandwidth data transmission applications ranging from online gaming and streaming video to datacenters, cloud computing, IoT, and 5G networks, and smart city infrastructure.
Leadership Comments
“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.”
KYOCERA AVX 550/560 Series UBCs are also RoHS compliant and shipped on tape in reel in quantities of 500–20,000.
