Customer Servicecompensation of the power factor is the one of its internal heating. This heating, provoked by the losses of the components that are placed inside, produces an increase of the temperature that should be lower to the maximum working temperatures of the equipment and capacitors.

1. Temperature-compensating-type multilayer ceramic capacitors (Class 1 in the official standards) This type uses a calcium zirconate-based dielectric material whose capacitance varies almost linearly with temperature. The slope to that temperature is called the temperature coefficient, and the value is expressed in 1/1,000,000 per 1°C (ppm/°C).
The temperature characteristics of ceramic capacitors are those in which the capacitance changes depending on the operating temperature, and the change is expressed as a temperature coefficient or a capacitance change rate. There are two main types of ceramic capacitors, and the temperature characteristics differ depending on the type. 1.
The capacitance value stated by the manufacturer is established at a reference temperature of 25°C. TCC should always be considered for applications operating above or below this temperature.
