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.
Capacitor is one of the three most common passive electronic components, along with resistors and inductors. It is widely used in various electronic circuits, and its performance can affect the characteristics of electronic circuits.
The burgeoning adoption of automated meter reading (AMR) by power utilities continues to propel the growth of smart meters. This transition away from periodic physical meter readings towards near real-time consumption data not only curtails operational expenses but also facilitates enhanced energy use management for both utilities and consumers.
Traditionally, aluminum electrolytic capacitors and tantalum electrolytic capacitors have been widely used in smoothing and decoupling applications that require large capacitors. With the increase of capacitance value, MLCC is replacing various electrolytic capacitors in power circuits and other applications.
Within the intricate domain of electronic components, multilayer ceramic capacitors (MLCCs) stand as stalwarts, embodying versatility, efficiency, and compactness in their design and functionality.
Electrolytic capacitors are widely used in household appliances and various electronic products. Polarized electrolytic capacitors usually play the roles of power supply filtering, decoupling, signal coupling, time constant setting, and DC isolation in power supply circuits or intermediate and low frequency circuits.
