3A Shielded Type SMT Chip Miniaturized Power Inductors Wire Wound Ferrite Core
1.Product Description
The 3A Shielded Type Chip Miniaturized Power Inductor is a high - performance electronic component designed to meet the demands of modern, space - constrained electronic devices. With a maximum current - handling capacity of 3A, it can efficiently handle the power requirements of various power - management circuits. Its shielded structure is a key feature. The shielding material effectively reduces electromagnetic interference (EMI), both preventing the inductor from being affected by external electromagnetic fields and minimizing the interference it emits to other components on the circuit board. This makes it particularly suitable for use in high - density circuit designs where components are closely packed together.
The chip - type design allows for easy surface - mount technology (SMT) assembly, which simplifies the manufacturing process and improves the overall reliability of the circuit. Its miniaturized form factor is another advantage. In today's era of miniaturized electronics, such as in smartphones, tablets, and wearable devices, space on the printed circuit board (PCB) is at a premium. This inductor's compact size enables it to fit into tight spaces, making it an ideal choice for power - related applications in these devices. Whether it's used in voltage - regulation circuits to smooth out power fluctuations or in power - conversion modules to store and release energy, the 3A Shielded Type Chip Miniaturized Power Inductor offers a reliable and space - saving solution for power management in miniaturized electronic devices.
2.Features
1. High current-carrying capacity: the maximum current carrying capacity is 3A, which can provide stable power supply for circuits with high power demand and meet the power demand of electronic components with high current demand, such as high-performance processors, high-power RF modules, etc., and ensure that the equipment can work stably even under high loads.
2. Excellent shielding performance: the use of special shielding structure and materials, can effectively block the internal magnetic field generated by the leakage, reduce the electromagnetic interference to the surrounding electronic components, but also against external electromagnetic interference on their own performance, to enhance the stability of the work in the complex electromagnetic environment. In the dense circuit board layout, it can avoid signal distortion or circuit failure caused by electromagnetic interference.
3. Miniaturized design: Continuing the compact shape of SMD miniaturized power inductors, it is suitable for layout on circuit boards with limited space. Whether it is thin and light notebook computers or compact IoT devices, it can be easily adapted to provide assistance in realizing miniaturization and thinness of equipment.
4. High precision and stability: high inductance precision, in different operating temperatures, voltage conditions, can maintain stable inductance performance, to ensure the consistency of circuit parameters, for the inductance value of the circuit of the stringent requirements of the accuracy of the circuit to provide a reliable guarantee, to reduce the inductance fluctuations brought about by the circuit performance deviation.
5. Low loss characteristics: with low DC resistance and core loss, in the process of transmitting current, energy loss is small, low degree of heating, not only to improve the efficiency of energy utilization, but also extend the service life of the equipment, reduce the probability of equipment failure caused by overheating.
6. Convenient for SMT processing: SMD package form, fully adapted to the surface mount technology (SMT), can be quickly and accurately mounted on the circuit board with the help of automated equipment to improve production efficiency, ensure consistency of production quality and reduce production costs.
Structure and composition:
Chip inductors are a commonly used electronic component. When the current passes through the wire, a certain electromagnetic field will be generated around the wire, and the wire in this electromagnetic field will generate an induced electromotive force-self-induced electromotive force, which we call electromagnetic induction. In order to enhance electromagnetic induction, people often wind the insulated wire into a coil with a certain number of turns.
