T38*19*13 Toroidal Wirewound Inductor

Magnetic Ring Inductor is an electronic component components, the main role is a role of electromagnetic induction conversion, the simpler inductor can be a wire, it can be used for antenna. The electrical energy will be converted into electromagnetic waves, more complex is a hollow line figure, it can be used for frequency selection circuit and RF transmitter circuit, more than the first two Inductors, there are I inductors, can be used for filtering, energy storage. There is also a common mode inductor available to resist the efficacy of dry together, etc.

In the high frequency band, the impedance is mainly composed of resistive components. As the frequency rises, the magnetic permeability of the core decreases, leading to a reduction in the inductance of the inductor and a reduction in the inductive component, but then the loss of the core increases and the resistive component increases, leading to an increase in the total impedance. When the high frequency signal passes through the ferrite, the inductive electromagnetic interference is absorbed and converted into a form of thermal energy consumption. In the low frequency band, the impedance is mainly composed of inductive reactance, R is very small at low frequencies, the magnetic permeability of the core is high, so the inductance is large, inductance L plays a major role, electromagnetic interference is reflected and suppressed, and at this time the loss of the core is small, the whole device is a low loss, high quality factor Q characteristics of the inductor, this inductor is easy to cause resonance, so in the low frequency band may appear after the use of ferrite beads Interference enhancement phenomenon.
