Ceramic capacitors carry medical grade approval

By Graham Prophet

The series is available in several different dielectrics, case sizes, voltage and capacitance ratings; MQ Series medical-grade MLCCs are available in eight EIA case sizes spanning 0402 to 2225, and four dielectric materials: NP0 (C0G), X7R, X7S, and X5R. Voltage ratings for the series range from 4V to 100V, capacitance values span 1 pF to 100 µF, and capacitance tolerances extend from ±0.1pF to ±30%. MQ Series capacitors are also available with four termination options: plated Ni/Sn, 60/40 Sn/Pb, 5% minimum Pb-plated solder, and gold plated.


NP0 (C0G), X7R, and X7S MQ Series MLCCs are rated for operating temperatures spanning -55°C to +125°C. Operating temperatures for X5R MQ Series MLCCs range from -55°C to +85°C. MQ Series capacitors in 0402, 1210, 1812, 1825, and 2225 cases are compatible with reflow soldering, and 0603, 0805, and 1206 cases are compatible with both reflow and wave.
