What Are the Applications of Shielded Inductors?
A shielded inductor, also known as a shielded inductor, is a device used to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). It uses the conductivity of shielding materials to limit electromagnetic energy within a certain range, thereby protecting the circuit from external interference.

The main functions of shielding inductors are as follows:
1. Filtering effect: Shielded inductors can be used as filters to effectively filter out harmful electromagnetic waves in transmission channels such as power lines and signal lines, thereby avoiding the impact of these interferences on the circuit.
2. Noise suppression: Shielded inductors can suppress noise in the circuit and reduce distortion and distortion during signal transmission.
3. Improve radiation performance: For equipment that needs to emit radio signals, such as wireless communication equipment, remote controls, etc., shielding inductors can improve their radiation performance and enhance the strength and quality of the signal.
4. Protect personal safety: Shielding inductors can effectively prevent the impact of electromagnetic radiation on human health and reduce electromagnetic pollution to the surrounding environment.
Shielded inductors are widely used in high-power devices such as audio and power control boards. What is the specific function of the inductor? The shielded inductor is a magnetic shielding structure, which mainly plays the functions of filtering, oscillation, delay, current blocking, filtering, etc.
It also shields signals, filters noise, stabilizes current, suppresses EMI, etc. Among them, the most common capacitor acting on the inductor constitutes the LC filter circuit. Capacitors have the characteristics of “DC resistance and AC resistance”, while inductors have the functions of “DC resistance and AC resistance”.
If a multi-disturbance DC current passes through the LC filter circuit, the AC disturbance signal will be consumed by the inductor into heat energy; when a relatively pure DC current passes through the inductor, the AC disturbance signal will turn into magnetic induction and heat energy. The higher the frequency, the more susceptible it is to the inductor. Impedance suppression, thereby suppressing disturbance signals with higher frequencies.
Direct current DC: The so-called DC means that in a DC circuit, the sensor is like a wire and does not play any role. AC Resistance: In an AC circuit, the inductor has impedance i.e. XL and the current in the entire circuit decreases making communication difficult.
Inductor resistance effect: The self-induced electromotive force of the induction coil changes with the coil current. The sensor can also shield signals, filter noise, stabilize current, and suppress electromagnetic interference.
