2.2μF 50V Ceramic Capacitor X7R 1812 (4532 Metric) 0.177" L x 0.126" W (4.50mm x 3.20mm)

17 X7R Dielectric General Specifications X7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials. X7R is the most popular of these intermediate dielectric constant materials. Its temperature varia- tion of capacitance is within ±15% from -55°C to +125°C. This capacitance change is non-linear. Capacitance for X7R varies under the influence of electrical op- erating conditions such as voltage and frequency. X7R dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.
