Ceramic Capacitor Temperature Range

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

Ceramic capacitor temperature range.

Characteristics precision and tolerances. There are two classes of ceramic capacitors available today. Capacitors for ac applications are primarily film capacitors metallized paper capacitors ceramic capacitors and bipolar electrolytic capacitors. A typical performance for the change of capacitance with temperature is 22 to 56 over a range of 10 c to 55 c.

The second character indicates the maximum temperature. Some capacitors are non linear. Temperature range ceramic capacitors class 1 paraelectric np0 30 ppm k 0 5 55 125 c ceramic capacitors class 2 ferroelectric x7r 15 55 125 c ceramic capacitors class 2 ferroelectric y5v 22 82 30 85 c frequency dependence of capacitance. Only available as leaded components.

Based on the working temperature range temperature drift tolerance different ceramic capacitor classes are defined. Class 1 and class 2. The third character indicates the maximum amount of capacitance change over the part s temperature range. The theoretical range is from 45 c to 200 c.

Ceramic capacitor dielectrics vary from one manufacturer to another but common compounds include titanium dioxide strontium titanate and barium titanate. Class 1 ceramic capacitors. The temperature coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. Ceramic capacitor dielectrics are defined by a three character eia code that specifies the material s capacitance stability over a specified temperature range.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The rated ac load for an ac capacitor is the maximum sinusoidal effective ac current rms which may be applied continuously to a capacitor within the specified temperature range. The spec for r capacitors such as x5r and x7r is 15.
