Ceramic Capacitor Temperature Ratings

5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c.

Ceramic capacitor temperature ratings.

These capacitor characteristics can always be found in the data sheets that the capacitor manufacturer provides to us so here are just a few of the more important ones. The second character indicates the maximum temperature. Ceramic names temperature coefficients α α tolerances and letter codes for α. The first character indicates the lowest temperature that the capacitor can handle.

This tutorial explains how ceramic capacitor type designations such as x7r and y5v imply nothing about voltage coefficients. Nominal capacitance c the nominal value of the capacitance c of a capacitor is the most important of all capacitor. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. Mlccs are used instead if capacitance values allow.

The third letter gives the maximum tolerance from that in ppm k. Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size. The capacitor as with any other electronic component comes defined by a series of characteristics. Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more.

Multi layer ceramic capacitor mlcc. The reality of modern small form factor ceramic capacitors is a good reminder to always read the data sheet. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. Ceramic capacitors which are usually tiny pancakes with two pins typically list the tolerance value as one letter immediately after the three digit capacitance value.

Engineers must check the data to know really know how a specific capacitor will perform under voltage.
