Fixed inductors are a type of passive electrical component that is designed to provide a specific inductance value in an electrical circuit. The ER1025-25JP is a particularly small and low-cost cylindrical inductor with optimized miniature size design. It is a surface mount, along the bottom of the device. It is available with various inductance values from 1µH up to 22µH and DC resistance values from 0.012 Ω up to 0.14 Ω. It is also equipped with 10−25/25P and 20−25/25P packages for customers to choose from.

Application Field

ER1025-25JP is widely used in high-frequency circuits, especially of portable systems. It can be used as an indexing component in multiple electronics applications such as amplifiers, neural networks, wireless communication, MEMS resonators, and others. Because of its optimized miniature size, the ER1025-25JP is suitable for use in space-limited environments, such as handheld electronics, watches, and other consumer electronics.

Working Principle

The basic function of the ER1025-25JP inductor is the same as other inductors, such as providing inductance in an electrical circuit to help complete certain circuit operations. The working principle of the ER1025-25JP is simple. By varying the number of turns around a central lead or between two leads, the inductance value can be changed. When a DC current is applied to an ER1025-25JP, the generated magnetic flux and electric field will be the same. Therefore, when a variable DC current is applied through the inductor, a time-varying magnetic field will be created which varies its resistance with the current. When the current increases, the inductance value of the inductor drops, thus reducing the amount of current flowing through it.

Manufacturing wise, the ER1025-25JP inductor incorporates a proprietary feature that reduces the amount of high frequency interference. This is done by using a triple-shielding structure that includes multiple layers of copper foil that redirects the electric field and cancels out the magnetic field. Due to this feature, the ER1025-25JP inductor is capable of providing high-frequency compatible inductance with exceptionally low noise. The use of an advanced epoxy sealing structure also helps to improve the inductor’s reliability and durability.

Finally, the ER1025-25JP inductor is designed to take advantage of its patented technology that reduces DC resistance and improves heat dissipation. It is designed to minimize contact between inductor parts and leads in order to reduce DC resistance for high current applications. It also features a high permeability material for better heat dissipation. Overall, this feature enables the inductor to work efficiently and last longer than traditional inductors.

The ER1025-25JP can be a great choice for those who are looking for reliable, high-efficiency, and low-cost inductors with optimized size and performance. Its small size, reliable performance, cost-effective solution, and its compliant with the RoHS standard make it perfect for use in multiple applications.
