We provide customers with not only devices, but also active + passive solutions from technology application to sales service

Power supplies are widely used in various electronic equipment or systems. The performance of the power supply directly affects the normal operation of the equipment or system. How to make the power supply more stable and better in the application, the key lies in the rectification and filtering of the power supply. Using high-quality and stable electronic components for filtering, with obvious frequency characteristics and noise absorption capabilities, purchasing electronic materials that are ideal for power supplies has become an important decision-making element. Power supply applications generally include power adapters, desktop power supplies, or server power supplies. The passive components required for power supply must be exposed to high temperature fluctuations and still maintain high product stability, and have ultra-low ESR (equivalent series resistance) values ​​and high ripple current ratings. The high capacitance value and low equivalent series resistance (ESR) characteristics of this series of products allow to maintain low impedance at high frequencies to support noise suppression and wave absorption in various applications. In this application, space is the key factor, and cost and highest efficiency are the priority considerations.

How to choose electronic components used in high-quality power products, such as chip capacitors, high-voltage chip capacitors, chip resistors, chip inductors, tantalum capacitors, precision resistors, electrolytic capacitors, voltage regulators Electronic components such as diodes, rectifier diodes, and light-emitting diodes. It plays an important and decisive role in improving the performance parameters of the power supply.
