6 FAQs about [Capacitor case temperature standard requirements]

What is the maximum operating temperature of a capacitor?

*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.

What is a temperature compensating ceramic capacitor?

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).

What are the temperature characteristics of ceramic capacitors?

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.

What is a Typical capacitance temperature?

The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics. And the tables below show the excerpts of applicable EIA and JIS standards. *3 It may differ from the latest JIS standard.

What temperature should a capacitor be dried at?

However it is advisable to dry immediately with hot air, which is best achieved at 85°C for few minutes. After having a capacitor exposed to high temperatures such as direct sunlight or heating elements, the capacitor life may be adversely affected.

What are the different types of ceramic capacitors?

Here is a chart on the different classes and definitions: Class III (or written class 3) ceramic capacitors offer higher volumetric efficiency than EIA class II and typical change of capacitance by −22% to +56% over a lower temperature range of 10 °C to 55 °C. They can be substituted with EIA class 2- Y5U/Y5V or Z5U/Z5V capacitors
