6 FAQs about [Capacitor ambient temperature and humidity range]

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 the relative humidity coefficient of a capacitor?

βc The values of given in table are valid for a relative humidity range of 50% to 95%. At relative humidity below 30%, the humidity coefficient is relatively low. Wide variations are to be expected at relative humidity above 85%. Figure 11 shows typical capacitance/humidity characteristics of different capacitor styles.

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 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 temperature should a capacitor be stored?

For long periods of storage keep capacitors at cool room temperatures and in an atmosphere free of halogen gases like chlorine and fluorine that can corrode aluminum. Storage temperature ranges are from –55 ºC to the upper limit of the operating-temperature ranges. Sources: Capacitor Selection Guide - KEMET (.PDF)

What determines a high-temperature limit of an electrolytic capacitor?

Largely the formation voltage sets the high-temperature limit. Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte.
