A polymer aluminum capacitor is a type of capacitor that uses a conductive polymer instead of a liquid electrolyte. The conductive polymer serves as the cathode, while the anode is typically made of aluminum.
Around 2008, film capacitors demand were very huge in led lighting and in power meters. X2 MKP Capacitors 0.47uF 0.22uF 0.1uF were widely used in power meter. While, manufacturers of power meter found a problem, after some time, the capacitance of above 0.22uF 0.1uF 0.47uF film capacitors faced a capacitance failure, that X2 MKP capacitors’ capacitance was decreasing.
Varistors, which is also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have electrical characteristics similar to back-to-back Zener diodes.
In the world of electronic components, chip aluminum capacitors have emerged as indispensable elements due to their compact size, high capacitance values, and versatile applications. This article delves into the characteristics, benefits, and various applications of chip aluminum capacitors, shedding light on their significant role in modern electronics.
Polymer tantalum capacitors, also known as solid tantalum capacitors with conductive polymer electrolyte, are a type of electrolytic capacitor with improved performance characteristics compared to traditional tantalum capacitors.
The film capacitor is a non-polarized capacitor and its dielectric is made using thin plastic films. These plastic films are sometimes metallized and are available in the market under the name “metallized capacitor”.
Compare with 20 years ago, China’s capacitors technology become very mature. Many high end capacitors, like DC link film capacitors, hybrid tantalum capacitors, High Q MLCC can be produced by Chinese local manufacturers. Some good capacitors factory can supply similar quality as Kemet, AVX, Vishay, Epcos.
The polarity marking on a tantalum capacitor indicates the orientation in which the capacitor should be placed on a circuit board or within a circuit. Tantalum capacitors are polarized components, meaning they have a positive and a negative lead. It's crucial to connect them correctly in a circuit to ensure proper functionality and to prevent potential damage.
recent advancements in supercapacitor technology have presented an exciting alternative that offers numerous advantages over conventional batteries. This article explores the benefits of employing supercapacitors in smart meters and their potential to revolutionize the industry.
The suitable operating conditions of tantalum capacitors are -55-+125 degrees, and the rated voltage can be applied within 85 degrees for testing. It is said that such conditions have shown that the temperature characteristics of tantalum capacitors are very good, but one thing is often overlooked, that is, under this condition, the test is carried out with a protective resistance of 1000 ohms.
High Voltage (HV Capacitors) ceramic capacitors are economical capacitors, with high reliability performance. HV Capacitors are ideally suited for applications such as snubbers in high frequency power converters, resonators in SMPS, and high voltage coupling, DC blocking, by-pass circuit.
The basic function of capacitors is charging and discharging, but many circuit phenomena extended from this basic charging and discharging function make capacitors have various uses. For example, in electric motors, we use them to generate phase shift;
Each day brings a new technical innovations, and the demand for smaller, more portable and more functional electronics.
UF capacitos has equivalent, 4 weeks delivery, cost down around 50~300%. many series like, long life to 20000H, High temp 125C. low ESR, etc.
