PTKM75R-180SM

Fixed Inductors

Fixed inductors are basic components that have been widely used in the field of signal transmission and detection. Its structure and working principle are relatively simple. One of the most commonly used fixed inductors is the PTKM75R-180SM series. This series of fixed inductors consists of several wide applications. In terms of its structure, it is a mold-encapsulated structure consisting of a housing, a ferromagnetic core, and three windings connected in series.

The ferromagnetic core consists of high permeability material that has the ability to effectively concentrate and maintain magnetic flux. In addition, the windings are usually formed by using a double-layer continuous wire to ensure that the winding has better continuity. The fixed inductor operates by utilizing the principle of magnetic reluctance, which means that when current passes through the three windings, an electromagnetic field will be generated. The coil core is used to limit the magnetic field generated by the windings so that only a small amount of leakage flux can be produced.

The variety of applications for fixed inductors has made them popular for use in the field of signal transmission and detection. The signal frequency of this series of inductors can reach 20MHz, and the working frequency characteristic is relatively stable. Therefore, they are extensively utilized in electronic and electrical circuits such as transmitters, receivers and oscillators. As an important component in circuits, it improves the stability of the circuit and ensures its signal transmission efficiency. Another advantage of fixed inductors is that it has good low frequency noise performance, which can effectively eliminate low frequency interference during signal transmission.

The PTKM75R-180SM series of fixed inductors are an ideal choice for signal transmission and detection applications, as they provide excellent frequency stability, low electromagnetic interference, and good low frequency noise performance. As an important component in the field of signal transmission and detection, the fixed inductor is able to provide stable signal transmission and improve the overall performance of electronic and electrical circuits.
