The application of surface mount technology (SMT) has become very common, and the proportion of electronic products assembled by SMT has exceeded 90%. With the development of small SMT production equipment, the application range of SMT is further expanded. Aviation, aerospace, instrumentation, machine tools, and other fields are also using SMT to produce a variety […]

SMD resistor introduction: Chip resistors are also called chip-fixed resistors. Chip fixed resistors are commonly known as SMD resistors, which are a kind of metal glass shaft resistors. It is a resistor made by mixing metal powder and glass shaft powder and printing it on the substrate by screen printing. It is resistant to humidity, […]

When many customers buy capacitor products, the most common concern is the service life of capacitors. Nothing in the world can last for a long time. The same is true for capacitors. Today, Aillen capacitor manufacturers will introduce you to the use of capacitors. Life span. For example, a capacitor with a rated maximum temperature […]

How to judge the quality of patch capacitors? In fact, the quality of chip capacitors can be seen from the appearance, color, etc., and then come to understand it. From the aspect of appearanceIf it is a qualified SMD capacitor, then the appearance size should be the same as the marked size or the size […]

Multilayer ceramic capacitors are laminated ceramic dielectric membranes with printed electrodes in a staggered manner. After one-time high-temperature sintering to form a ceramic chip, the two ends of the chip are sealed with a metal layer to form a monolithic structure. , So it is also called a monolithic capacitor. Multilayer ceramic capacitors often have […]

Engineers need to know how components failThe failure of components is directly affected by factors such as temperature, humidity, voltage, and machinery. The effect of temperature changes on capacitanceThe temperature change will cause the dielectric loss of the capacitor to change, thereby affecting its service life. When the temperature rises by 10°C, the life of […]

Aluminum electrolytic capacitors remain a popular choice in power supplies due to their low cost. However, they have limited life and are sensitive to both hot and cold temperature extremes. Aluminum electrolytic capacitors are constructed with foils placed on opposite sides of paper saturated with an electrolyte. This electrolyte evaporates over the capacitor’s lifetime, altering […]

Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more. Advantages of MLCC include:Small parasitic inductance gives better high-frequency performance compared to aluminum electrolytic capacitors.Better stability over temperature, depending on the temperature coefficient.DisadvantagesSmall capacitance per volume, […]

Long-term storage of aluminum electrolytic capacitors may lose their effect because electrolytic capacitors need to be regularly applied with rated voltage during long-term storage, which will stimulate and maintain the activity of the electrolyte, otherwise, the electrolyte in the electrolytic capacitor will lose its activity and deteriorate. After the electrolyte loses its activity and ages, […]
