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 -
How to Evaluate the Service Life of Varistors
With the development of science and technology, the varistors have been used more and more widely. The common ones are power supply systems, surge suppressors, security systems, motor protection, automotive electronic systems, household appliances, etc. So how do we evaluate the service life of v...Read more -
Differences Between Varistor 10D 471K and 14D 471K
The resistance value of a varistor changes with the voltage within a certain current and voltage range, and it can also be said to be a resistor whose resistance value is sensitive to voltage. Another English name for varistor is “Voltage Dependent Resistor”, abbreviated as “VDR...Read more -
Film Capacitors in LED Lights
LED lighting has become an important light source in daily life. LED lighting products include bulb lamps, fluorescent lamps, street lamps, industrial and mining lamps, etc. Some lighting products have small internal space but high temperature, so the capacitors required are also small, high temp...Read more -
Why Supercapacitors Can Be Used In New Energy Vehicles
New energy vehicles are currently the hottest topic in the automotive industry. Europe is one of the earlier regions in the global energy transformation. Europe has vigorously developed new energy sources, issued a series of emission regulations and implemented measures to reduce carbon emissions...Read more -
What Does The 102 3KV Mean On Ceramic Capacitor
There are two printings on the ceramic capacitor, one is the nominal capacitance, and the other is the rated working voltage. What does the ceramic capacitor 102 3KV mean? Let’s talk about the two parameters respectively. 1. 102 is the capacitance value, and 102 indicates the capaci...Read more
