In the hot summer, are the film capacitors in your electronic devices in good condition?

It’s too hot! How can Guangdong be so hot in summer? It’s not just Guangdong that’s hot in summer. Many places are very hot in summer, and high temperature warnings have been issued. Faced with such hot weather, many netizens have complained, and the topic "Do you turn on the air conditioner all night?" has become a hot search.

Seeing this hot search on Weibo, the editor who is in Guangdong has something to say. The weather in Guangdong is really hot at night. The room is stuffy and there is no wind, like a steamer. People are getting dizzy from the heat. It is a torture for the editor to sleep without turning on the air conditioner and only relying on an electric fan and a cool mat. It can be said that in summer, basically, you can't do without air conditioning, refrigerators, electric fans, etc.

As the temperature rises, the frequency of use of electronic devices such as air conditioners and fans in many households is also increasing, and they are also facing the test of high temperatures. In these electronic devices, film capacitors are an important electronic component, playing a variety of roles such as charge storage, filtering, coupling, etc. With such high temperatures, can the film capacitors in these electronic devices withstand it?

Film capacitors are a common type of capacitor, consisting of metal film and dielectric film. They are widely used in various electronic devices due to their small size, light weight, low internal temperature rise, low loss, and good self-healing ability.

Generally, the operating temperature range of film capacitors is -40℃~+105℃. When the operating temperature of film capacitors exceeds 105℃, the dielectric inside may deform, crack, and cause the capacitor to malfunction. Therefore, in hot summer weather, if the internal temperature of electronic equipment exceeds the operating temperature range of film capacitors, film capacitors may be damaged.

So how do you protect the film capacitors in electronic devices? On the one hand, you can actually add an electric fan or radiator to the electronic device to keep it well ventilated and lower the temperature inside the device to reduce the workload of the film capacitor. On the other hand, you can also choose high-quality film capacitors, which have more optimized materials and structures, so that they can better cope with high temperature environments.

In short, it is still necessary to protect film capacitors in hot summer weather. Only by ensuring that the internal temperature of electronic equipment is within the operating temperature range of film capacitors can the normal operation of film capacitors be guaranteed, thereby ensuring the normal operation of electronic equipment.
