  Aillen is a Chinese   inductor manufacturer . It provides high-quality products and good after-sales service. It has the concept of customer first. Today I will introduce to you what inductors and what the role of inductors is. What is inductance? Inductance is a property of a closed loop. When the coil passes current, a magnetic field is induced in the coil, and the induced magnetic field will generate an induced current to address the current in the coil. The relationship between this current and the previous interaction is called electrical inductance, which is also called inductance. Inductance is a physical quantity that measures the ability of a coil to generate electromagnetic induction. When a current is applied to a coil, a magnetic field will be generated around the coil, and magnetic flux will pass through the coil. The greater the power supply to the coil, the stronger the magnetic field and the greater the magnetic flux passing through the coil. Experiments have proved t

  How to judge the quality of   chip 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 appearance If it is a qualified SMD capacitor, then the appearance size should be the same as the marked size or the size marked on the manual and the outer packaging, but if you get a SMD capacitor, you find that the appearance size has changed, for example, there are slight flaws or slight cracks, then there may be some problems with the size of the appearance. The introduction shows that there is a problem with the capacitor. Secondly, look at the tin feet. If the tin feet have black spots, defects, cracks, and the unbalanced ratio between the top and bottom of the tin feet, it means that the quality is also problematic. The quality of chip capacitors can also be judged by color. If it is a normal factory capacitor, the appearance and color are uniforms, and the same batch will not appear black, gra

  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 of 85°C will have a service life of 1000H under an ambient temperature of 85°C, and when the ambient temperature is reduced to 60°C, the service life can be extended to 10000H. When the ambient temperature drops to 40°C, The service life can reach 80,000H. Factors affecting the service life of capacitors: The service life of a capacitor is not only related to the temperature of the environment, but also to the magnitude of the ripple current. Since thermal stress has a decisive influence on the service life of the capacitor, the heat loss caused by the ripple current is an important factor affecting the service life of the capacitor. Ripple current re
