When a DC voltage is applied to a capacitor, the capacitor itself draws charging current from the power supply and charges it to a value equal to the applied voltage
Solid tantalum capacitor is tantalum powder compression molding, sintered in a high temperature furnace into the anode body, the dielectric is the anode body into the acid empowered, the formation of porous amorphous Ta2O5 dielectric film, the work of the electrolyte for the high temperature decomposition of manganese nitrate solution to form MnO2, through the graphite layer as a lead to connect with.
In the capacitor industry, different capacitors have different uses, each has its own advantages, and widely used in mechanical equipment. However, there are many people do not quite understand the knowledge of capacitors, the following explanation of high-voltage ceramic capacitors.
In 2018, Murata announced the discontinuation of leaded ceramic capacitors in the market. In people's perception, leaded ceramic capacitors are considered old-fashioned products, with the trend in new technology favoring surface mount device (SMD) types used in devices like laptops, smartphones, wireless phone chargers, and electric cars.
Power supply is often the most neglected part of our circuit design process. In fact, as a good design, power supply design should be very important, which greatly affects the performance and cost of the entire system.
A Capacitor is passive electronic device, second in use only to that of a resistor. Capacitors can be found in virtually all electronic devices. Simply put, a capacitor is two electrodes (conductors) separated by a dielectric(insulator).
MLCC - Multilayer Ceramic Capacitor, commonly known as surface-mount capacitor, can cause noise and whining issues. Why is this?
Aluminum electrolytic capacitor is made of aluminum cylinder as negative pole, which is filled with liquid electrolyte and inserted into a piece of bent aluminum tape as positive pole. It also needs to be processed by DC voltage, so that a layer of oxide film is formed on the positive pole piece to make the medium. It is characterized by large capacity, but leakage, poor stability, positive and negative polarity, suitable for power supply filtering or low frequency circuit.
Aluminum electrolytic capacitors are essential in many electronic devices, from power supplies to audio amplifiers. Their unique properties make them popular for engineers and designers who need reliable and cost-effective capacitors.
Temperature Coefficient of the abbreviation, meaning negative temperature coefficient, refers to the negative temperature coefficient of semiconductor materials or components, usually we mention the NTC refers to the negative temperature coefficient thermistor, referred to as NTC thermistor.
The MF72 NTC (Negative Temperature Coefficient) Thermistor, primarily composed of transition metal oxide materials. Its classification within the negative temperature thermistor category denotes its crucial role in managing surge currents within electrical circuits.

Ceramic capacitor is a capacitor whose dielectric material is ceramic. The structure consists of two or more alternating layers of ceramic and metal layers, which are connected to the electrodes of the capacitor.
Voltage Sensitive Resistors (VSRs) are not ordinary resistors, but a kind of components with transient voltage suppression function, the effect is the same as TVS.
Film capacitors can be used in many fields, of which the largest use in the lighting field. There are two main types of film capacitors, one is polyester film and the other is polypropylene film, they have the advantages of stable capacity, high reliability, high insulation resistance, low loss, self-healing, low price, etc.
