SPD42R-122M

Fixed Inductors are used in a variety of applications due to their simple design and good performance. One of the most popular types of Fixed Inductor is the SPD42R-122M, which is widely used in the telecom and consumer electronic sectors and is suitable for a variety of applications. This article will discuss the application field and working principle of this particular inductor.

The SPD42R-122M is a high inductance, high current, low DCR Fixed Inductor. It is constructed with a ferrite core and a single copper winding. This particular type of inductor is designed to have high inductance and low DCR, meaning it is capable of operating at high frequencies while maintaining steady inductance values. Additionally, the inductor can handle higher currents, making it ideal for applications where large current spikes must be handled.

The SPD42R-122M is well suited for use in applications such as frequency tuning, transmission line applications, and filtering. It is an ideal choice for use in telecom and consumer electronic applications, such as mobile phone base stations and internet routers, as it is designed to provide stable, reliable performance in such high frequency circuits. Additionally, the inductor is also suitable for use in low frequency circuits such as power supplies, audio applications, and cable TV applications.

The working principle of this inductor is relatively simple. When a current is passed through a conductor, a magnetic field is created. This magnetic field passes through the core of the inductor and induces a voltage, which is called Self Inductance. As the magnetism is dependent on the current, the voltage induced in the inductor changes with the intensity of the current, resulting in a smooth, steady performance. Additionally, the core of the inductor also acts as a shield against external electromagnetic interference, further improving the performance of the device.

Overall, the SPD42R-122M Fixed Inductor is a reliable, high performance device that is suitable for a variety of applications. Its core is designed to provide excellent inductance and to shield against outside interference, while the copper winding helps to maintain a steady, reliable performance. Additionally, its low DCR and high inductance make it an excellent choice for telecom and consumer electronic applications, enabling it to operate well in high frequency circuits.
