Ceramic Disc Capacitor Temperature Coefficient

Z5u 10 c 85 c 22 56 20.

Ceramic disc capacitor temperature coefficient.

Eia code table for ceramic capacitor dielectrics. The theoretical range is from 45 c to 200 c. C0g np0 ceramics offer one of the most stable capacitor dielectrics available. Y5v 30 c 85 c 22 82 20.

A thermistor is a type of resistor whose resistance is dependent on temperature more so than in standard resistors the word is a combination of thermal and resistor thermistors are widely used as inrush current limiters temperature sensors negative temperature coefficient or ntc type typically self resetting overcurrent protectors and self regulating heating elements positive. Z5v 10 c 85 c 22. Y5u 30 c 85 c 22 56 20. The letter x as in x7r x5r corresponds to 55 c.

Y5p 30 c 85 c 10 10. Ceramic disc capacitor values. In addition to this they exhibit a non linear temperature coefficient and a capacitance that is dependent to a small degree on the applied voltage. 5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c.

As a result. A vendor can call a capacitor x7r x5r or any other of dielectric code as long as it meets the temperature coefficient specifications regardless of how bad the voltage coefficient is. Modern c0g np0 formulations contain neodymium samarium and other rare earth oxides. As the name indicates.

An american company in the midst of the apollo program launched in 1961. The second character indicates the maximum temperature. Ceramic names temperature coefficient. C0g np0 is the most popular formulation of the temperature compensating eia class i ceramic materials.

Class 2 ceramic capacitors. The first character indicates the lowest temperature that the capacitor can handle. Calcium titanate for capacitors with a negative temperature coefficient. Class 2 capacitors exhibit better performance for volumetric efficiency but this is at the cost of lower accuracy and stability.
