Audi to Increase Investment in Electric Mobility
Beijing time on December 4th, 2022, according to media reports, German automaker Audi will increase investment in electric mobility in the next five years, with an investment of up to 35 billion euros (about 42.5 billion U.S. dollars). Among the above-mentioned investment quotas, about 25 billion...Read more -
Can Ceramic Capacitors Be Used In Filter Circuits
Different filter circuits have different requirements for the capacitance of the capacitor. High-frequency filter circuits should use small-capacitance capacitors, while low-frequency filter circuits require large-capacitance capacitors. Ultra-high frequency filter circuits using small-cap...Read more -
Characteristics of Ceramic Capacitors
Ceramic capacitors are widely used in electronic equipment at present, accounting for about 50% of the total number of capacitors used, but many people do not know enough about their characteristics. In order to meet the standardization and requirements of product use, the following is an overvie...Read more -
Application of Supercapacitor in National Defense
Supercapacitor, as an important energy supply component in high-power pulse weapon equipment, is a new type of energy storage device that can burst out huge energy in a short period of time, and can be called the “energy core” of many military equipment. Its performance can be called ...Read more -
Analysis of Capacitor Failure
Capacitor failure means that a capacitor cannot work normally during normal working hours. The main parameters of capacitors are capacitance; loss value(also called DF value); withstand voltage; insulation resistance; and leakage current value. Usually, when many customers use capacitors, they wi...Read more -
Withstand Voltage and Capacitance Decrease in Capacitor
Film capacitors are widely used in electronic circuits because they have many excellent characteristics. But the capacitance and withstand voltage of film capacitors will decrease after a long period of use, which will seriously hinder the effect of use. So what are the factors for the reduction ...Read more -
The Printing on the Safety Capacitor Housing
In switch power supply and electronic circuits, there is an electronic component that can protect the circuit, which is called safety capacitor. The full name of the safety capacitor is the capacitor for suppressing electromagnetic interference of the power supply. If the external power su...Read more -
Ceramic Capacitor’s Coupling and Decoupling Functions
Ceramic capacitors are widely used in electronic circuits due to their advantages such as non-polarity, high temperature resistance, large specific capacitance, good moisture resistance, small dielectric loss, and high reliability. Ceramic capacitors are used in many places, and they play the rol...Read more -
Varistor in Parallel Circuits
The voltage dependant resistor or varistor is a resistive component which has the nonlinear volt-ampere characteristic. It can be used to clamp the voltage when the voltage of some circuits is too large and the electrical device cannot bear it, so as to protect the device. The abbreviation of the...Read more -
Two Factors Determine the Life of Ceramic Capacitors
Any product equipment has a service life, but the length of service life is affected by many factors. In recent years, the data of ceramic capacitors in the sales field of electronic components has been rising. What factors may affect the service life of ceramic capacitors? The life of the capaci...Read more -
The Self-healing Property of Film Capacitors
Film capacitors use metal foil as the electrodes, and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate as the dielectric. According to the type of plastic film, there are polyethylene capacitors (also called Mylar capacitors), polypropylene capacitors (also called P...Read more -
Notice! Causes of Safety Capacitor Overheating
Many electrical appliances will generate heat after working for a long time, such as televisions, electric fans, refrigerators, etc. These electrical appliances work continuously for several hours, and the outer shell of the body starts to heat up. Capacitors are no exception. A capacitor is an...Read more
