Low-loss MLCCs deliver wideband RF performance
Kyocera AVX has expanded its 550/560 series of ultra-broadband MLCCs to support high-speed, high-bandwidth optical communication systems. The capacitors provide reliable, repeatable RF/microwave performance from 7 kHz to 110 GHz and exhibit low insertion loss and flat frequency response. Depending on case size and capacitance value, typical insertion loss remains below 0.5 dB through 40–70 GHz and below 1 dB through 70–110 GHz.
The four new devices are available in 0402-size cases with capacitance values of 1 nF, 10 nF, 25 nF, and 47 nF and maximum working voltage ratings from 16 V to 100 V. With these additions, the 550/560 series offers a total of 15 devices in 01005, 0201, and 0402 case sizes with capacitance values spanning 1 nF to 220 nF. All of the capacitors operate over a temperature range of -55°C to +125°C.
The 550/560 lineup features a rugged one-piece construction with tin- or gold-plated nickel barrier terminations compatible with reflow soldering. These terminations are designed to prevent base metallization from leaching into the solder and forming brittle intermetallic compounds, which could cause cracking and solderability issues.
Visit the 550/560 series product page to download the datasheet, which includes S-parameter data and S2P Touchstone files for RF and microwave simulation. The four new part numbers will be stocked this November and available for order at DigiKey and Mouser Electronics.
