How to measure the capacitance and numerical value of SMD capacitor electrolysis? Chip capacitor electrolysis is measured by using a digital multimeter to measure the capacitance gear. For chip capacitors that are not suitable for testing on circuit boards, the measurement results are not accurate; Use a hot air solder……

To select a suitable long-life Electrolytic capacitor, multiple parameters such as voltage, capacity, etc. of Electrolytic capacitor should be selected according to the use scenario. What do different parameters of long-life Electrolytic capacitor mean?

Chip capacitors and resistors are currently commonly used components in large quantities. In terms of the chip capacitors and resistors consumed by AVX Company, there are different specifications such as NPO, X7R, Z5U, Y5V, etc. Different specifications have different uses. Below, we will introduce the performance and ……

The composition and structure of aluminum foil used for electrolysis are exquisite. For example, for anode foil, high purity is no longer required and is required to be as high as possible. In order to improve the initial corrosion point, mechanical strength, and performance of the dielectric oxide film, the foil shoul……

Polarity Electrolytic capacitor usually plays the role of power filter, decoupling, signal coupling, time constant setting, DC isolation, etc. In power circuits or intermediate and low-frequency circuits. Generally, it cannot be used in AC power circuits. When used as a filtering capacitor in a DC power supply circuit,……

Chip inductors are also divided into wire wound and stacked chip inductors: 1. Surface mounted high-power inductors. 2. It has the characteristics of miniaturization, high quality, high energy storage, and low resistance. 3. Mainly used in computer display boards, laptops, pulse memory programming, and DC-DC converters……

Chip capacitors are the most basic electronic components in circuits. I believe everyone is familiar with it. Almost any circuit or electronic product will have capacitors, but the role of capacitors is not fixed. Through different circuits and functions, there will be different effects. Let's explore together with Shi……

The capacity and withstand voltage marked on the body of aluminum Electrolytic capacitor with rated voltage are very important and are the most basic content for selecting capacitor. In actual capacitor selection, larger capacitors should be used for areas with fast current changes, but it is not necessarily better to ……

In components, capacitors can be said to have complex types and specifications, especially to adapt to different circuits and working environments. Even capacitors with the same capacity and rated voltage have multiple types and material characteristics to choose from. If a capacitor malfunctions, the usual solution is……

The size of the resistance value of a chip capacitor is usually related to temperature, material, length, and cross-sectional area. The physical quantity used to measure the resistance size affected by temperature is the temperature coefficient, which is defined as the percentage of change in resistance value for every……

Recently, many customers have asked how to distinguish the positive and negative poles of Electrolytic capacitor? Is there a graphic display?

In addition, direct contact between the extended cathode aluminum foil and the capacitor aluminum shell is also a good way to reduce thermal resistance. At the same time, it should be noted that the aluminum shell will carry negative electricity and cannot be used as a negative electrode connection. The capacitor must ……
