Multi-layer ceramic capacitors, also known as monolithic capacitors, are widely used in electronic precision instruments. Various small electronic devices are used for resonance, coupling, filtering, and bypassing. The basic structure of a simple parallel plate capacitor consists of an insulating in

Digital representation: The digital representation of the capacitor is usually used to represent the size of the capacity in three digits. The unit is pF. The two digits in the front represent the effective number of the capacitance value. The third digit number indicates the number of zero after th

Direct representation: 1. The direct representation of the unit marked. This representation is referred to as the common letter M for short: (10-3 Fala, note: 10 -3 square, the same); micromethod (10-6 Fala); n for short, Nana (10-9 Fala) and P (10-12 Fala) to indicate the capacity of the capacitor.

To select the appropriate capacitance value, the rated DC voltage, the allowed voltage ripple and the charge / discharge cycle should be checked. However, the following parameters should be considered when choosing an electrolytic capacitor for this application.　　The ripple current of the capacitor

The container is one of the most important passive components to achieve a wide range of voltage and current combinations. Although each capacitor can store electrical energy, dielectric technology plays an important role in the selection of capacitors for specific applications.　　The most important

The trimmer capacitor is also called semi adjustable capacitor, and its capacity is between 5 and 45pF. There are many kinds of them, and the following are the following: 1) Ceramic trimming capacitors: characterized by abrasion resistance and long service life. 2)Tube type trimming capacitor: also

Film capacitor manufacturers should pay attention to the selection of capacitors: rated voltage. The rated voltage refers to the voltage applied to the two ends of the capacitor when the capacitor is able to work normally, stably and reliably in a certain period of time in the circuit. The rated vol

A lot of people will have such a perception of film capacitors is a panacea for noise related problems, but the value of film capacitors is not limited to that. Designers often think of adding a few capacitors to solve most of the noise problems, but seldom consider the parameters other than capacit

There are many types of capacitor damage, which can generally be summarized as follows:1. early sexual faults. This refers to the failure of the power supply or the transmission of electricity, mostly due to poor manufacturing process or serious defects.2. there are occasional sexual faults. This re

The use of film capacitors in a wet environment makes the surface of the film capacitor gradually condensate. These water will increase the leakage current of the film capacitor, which causes the loss of the capacitor to increase. If the moisture in the surface of the film capacitor or the water in
