With the continuous advancement of science and technology, the new manufacturing process has brought many improvements to the performance of shielded inductors.
In terms of material preparation, the new process can achieve more precise control of material composition. For example, for the core material of the inductor, through advanced powder metallurgy process, magnetic powder with more uniform particles and more stable magnetic permeability can be prepared. This makes the inductance value of the shielded inductor more accurate and stable, and reduces the fluctuation of the inductance value under different working conditions. At the same time, the new material preparation process can also increase the saturation flux density of the core, so that the shielded inductor can withstand larger currents without magnetic saturation, thereby broadening its application range in high-power circuits.
In the winding manufacturing process, the new automated winding technology can achieve tighter and more regular coil winding. This not only reduces the resistance of the coil, reduces power loss, and improves the efficiency of the inductor, but also makes the distributed capacitance of the inductor smaller, thereby reducing unnecessary capacitance effects in high-frequency applications and improving the high-frequency characteristics of the inductor. For example, in high-frequency circuits in the field of communications, shielded inductors under new manufacturing processes can better filter high-frequency noise and ensure signal purity.
In addition, new packaging processes also play an important role in improving the performance of shielded inductors. Advanced packaging technology can provide better mechanical protection and electromagnetic shielding effects. For example, the use of multi-layer composite packaging materials can more effectively block the impact of external electromagnetic interference on inductors, while also preventing the magnetic field generated by the inductor itself from interfering with surrounding circuit components. Moreover, the new packaging process can make shielded inductors have better heat resistance and moisture resistance, and improve their reliability and stability in various complex environments. In short, the new manufacturing process has significantly improved the performance of shielded inductors in many aspects, enabling them to better meet the evolving needs of modern electronic equipment.
