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.
