Ceramic Capacitor Range

Class 1 ceramic capacitors.

Ceramic capacitor range.

The second character indicates the maximum temperature. The frequency characteristics of a capacitor differ greatly from one type of capacitor to another. Even multilayer ceramic capacitors come in a variety of types depending upon the raw materials used and the shape of each. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa.

Characteristics precision and tolerances. For instance ceramic capacitors made using x5r dielectric materials have an operating temperature range of 55 c to 85 c with an allowable variation in capacitance of 15 over that range and exhibit non linear capacitance value stability over that range. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. Over time a series of standard capacitor values have evolved just as with resistors and inductors.

The theoretical range is from 45 c to 200 c. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Based on the working temperature range temperature drift tolerance different ceramic capacitor classes are defined. The capacitance value will be calculated as follows.

There are two classes of ceramic capacitors available today. 5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c. Popular class 2 ceramic dielectrics include x7r which as a temperature range of 55 to 125 c with a δc c0 of 15 y5v which as a temperature range of 30 to 85 c with a δc c0 of 22 82 and z5u which has a temperature range of 10 to 85 c and a δc c0 22 56. The letter x as in x7r x5r corresponds to 55 c.

The first character indicates the lowest temperature that the capacitor can handle. Class 1 ceramic capacitors are used where high. Class 1 and class 2. Ceramic capacitor dielectrics vary from one manufacturer to another but common compounds include titanium dioxide strontium titanate and barium titanate.

Capacitors are available in a huge range of package styles voltage and current handling capacities dielectric types quality factors and many other parameters still they largely hold to this range of values. 15 100 1500 pf. A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. At high frequencies a multilayer ceramic capacitor has low impedance and exhibits excellent frequency characteristics.
