1. Environmental Adaptability
Operating temperature range: The operating temperatures needed by capacitors are different in various use cases. For example, capacitors working in high - temperature surroundings like industrial furnaces, kilns, and automobile engine bays require the selection of capacitor oils with a high flash point, low volatility, and great thermal stability. Meanwhile, capacitors in low - temperature environments, such as electronic equipment and refrigeration gear in polar regions, must choose capacitor oils with a low pour point so as to ensure that the capacitor oils can still operate properly at low temperatures.
2. Selection of Attention Factors
Dielectric loss factor: Capacitor oil with a low dielectric loss factor can decrease the energy loss under the influence of an electric field. It can also reduce the heating of the capacitor, enhancing the capacitor's efficiency and service life. Generally, we expect the dielectric loss factor to be at a relatively low level, for example, less than 0.005.
