Custom inductance High Current Integrated Shielded SMD Molding Power Inductor

1.Product Description

Shielded surface mount molded power inductor is a crucial component in modern electronic circuits. It adopts surface mount (SMD) technology, which makes it easy to install on printed circuit boards (PCBs), greatly saving space, especially suitable for electronic products that pursue miniaturization and high integration. Its molding design endows it with good mechanical stability, which can better resist vibrations and impacts during production and use.
The "shielding" feature is a major highlight of this inductor. Through a special shielding structure, it can effectively block the leakage of internal magnetic fields and also resist the influence of external electromagnetic interference on the inductance performance. In complex electromagnetic environments, such as communication base stations containing numerous electronic devices or compact laptops, this feature ensures stable operation of inductors, reduces electromagnetic interference to surrounding components, and ensures the normal operation of circuits. In addition, shielded surface mount molded power inductors perform well in handling high power and can withstand high currents, providing stable inductance values and efficient energy conversion for high-power applications such as power management modules and motor drive circuits, thereby improving the performance and reliability of the entire electronic system.

2.Characterization

1. Shielding characteristics
--Excellent electromagnetic shielding: With an efficient shielding structure, it can effectively suppress internal magnetic field leakage and prevent electromagnetic interference (EMI) to surrounding electronic components. At the same time, it can also resist external electromagnetic interference, ensuring that its inductance performance is not affected by complex external electromagnetic environments. For example, in high-density electronic devices such as server motherboards, where numerous components are close to each other, the shielding function of this inductor can avoid electromagnetic interference and ensure stable operation of each component.

--Reducing electromagnetic radiation: greatly reducing the electromagnetic radiation generated by itself, in compliance with relevant electromagnetic compatibility (EMC) standards. This is crucial for applications with strict restrictions on electromagnetic radiation, such as medical equipment, aviation electronic equipment, etc., to ensure that the equipment does not interfere with sensitive electronic systems in the surrounding area.

2. Surface mount and molding design
--Convenient surface mount: Using surface mount (SMD) technology, it facilitates automated installation on printed circuit boards (PCBs). This not only improves production efficiency, but also ensures installation accuracy and stability on the PCB, making it suitable for large-scale production. For example, in mobile phone manufacturing, high-speed placement machines can be used to accurately place and meet the needs of large-scale production.

--Durable molding structure: The unique molding process endows the inductor with good mechanical strength, enabling it to withstand a certain degree of vibration and impact. In application scenarios such as automotive electronics, the bumps and vibrations during vehicle operation will not easily damage the inductance, ensuring reliable operation in harsh mechanical environments.

3. Superior electrical performance
--High saturation current: capable of withstanding high DC currents without magnetic saturation, ensuring stable inductance values in high current applications such as power modules supplying high-performance processors, and ensuring normal circuit operation.

--Low DC resistance: Having a lower DC resistance helps to reduce energy loss caused by current passing through, minimize heat generation, and improve circuit efficiency. In portable devices, it can reduce power consumption and extend battery life.

--Broadband response: Maintaining stable inductance performance over a wide frequency range, it can adapt to signal processing requirements at different frequencies, and can play an excellent role in both low-frequency power filtering and high-frequency signal coupling and isolation.

4. Reliability and stability
--Adaptable to various environments: It has good temperature stability and can maintain stable electrical performance over a wide temperature range. It can work normally in both high-temperature industrial environments and low-temperature outdoor environments. At the same time, its packaging structure also has certain moisture-proof and dust-proof properties, which improves the reliability of use under different environmental conditions.

--Long service life: Due to its excellent electrical performance, sturdy structure, and adaptability to the environment, this inductor has a long service life, reducing the frequency of equipment maintenance or replacement due to inductor failures and lowering overall costs.
