Common problem

Capacitors are divided into polarized and non-polarized, and electrolytic capacitors are polarized capacitors, so in the practical application of electrolytic capacitors, they must be connected strictly according to polarity, and cannot acce...

Most people who have come across aluminum electrolytic capacitors have heard of ripple, high ripple or low ripple, but what is "ripple"? The ripple current or voltage is the high harmonic component of the current, which will bring the change...

The performance, storage life and service life of capacitors depend not only on the materials and workmanship of the capacitors themselves, but are also determined to a large extent by the environmental conditions in which they are located....

We all know more or less about electrolytic capacitors, but are we clear about the technical characteristics of electrolytic capacitors, such as temperature, pressure and standard requirements of capacitance, etc.? The following is a brief e...

Overview of polarized and non-polarized capacitors: The ideal capacitor has no polarity. However, in practice, manufacturers use special materials and structures when manufacturing large capacity capacitors, which leads to some actual capaci...

There are times when electrolytic capacitors fail, and the failure mechanism varies due to the different materials, structures, manufacturing processes, performance and use environments of various types of capacitors. Common failure modes: l...

Have you ever observed the top of an electrolytic capacitor? Many electrolytic capacitors have a cross at the top. Is this design for aesthetic purposes? Actually, it is not. This is the design of the capacitor for safety reasons. When an el...

When we manufacture and purchase electrolytic capacitors in the market, they are mainly divided into ordinary capacitors and high frequency capacitors. So what exactly is the difference between the two? I. The main function of electrolytic...

Due to the internal structure of electrolytic capacitors: electrodes, dielectric materials, electrolyte, and possible working conditions, the causes of explosion are analyzed as follows....

When the two plates of the capacitor are respectively connected to the positive and negative electrodes of the DC power supply,...
