The difference between magnetic beads and inductances
Time: 2024-05-24 Source: Author:
Magnetic beads are almost the most important device in EMC rectification, and often use it to rectify EMC.
The following is the difference between magnetic beads and inductances.
Clever is a filter similar to an inductance, and some data even look at it as a special inductance. From the perspective of the circuit, the magnetic bead is basically equivalent to the resistance and inductance series (the strange capacitance CX can be ignored), and the resistance and inductance values change with frequency.
The frequency range that magnetic beads can inhibit are widely used, from MHz levels to GHz level, which can be used. It is often connected on the signal line and power line, and is widely used because of high cost performance, good use, and high -frequency noise effect.
There are currently two forms of packaging commonly used in magnetic beads: plug -in and patch. Plug -in products are often used for large -current filtering. More often, magnetic beads (magnetic rings) need to be worn on the power line; and patch products are mostly used for signal wire filtering, and the current current is often limited.
In summary, the difference between magnetic beads and inductance is as follows:
1. The unit of the magnetic bead is Ohm (ω), and the unit of inductance is Henry (H);
2. Magnetic beads are mainly composed of iron oxygen, while the inductance consists of iron oxygen and coils;
3. Magnetic beads convert the communication signal into thermal energy, which is often used to consume energy; and the inductance transforms the AC signal into a magnetic energy for storage of energy;
4. Clever beads can play its maximum value in high -frequency signals. High -frequency filtering characteristics are often better, and the frequency range is wider than the inductance;
5. The focus of the two is to solve the EMC problem: Magnetic beads are mostly used to solve the radiation problem, and the inductance is mostly used to solve the conduction problem;
6. Magnetic beads are used for signal circuit, especially the combination of digital ground and simulation ground; inductor is mostly used for power filter circuit, focusing on circuit signal matching;
7. There are no coils and no distributed capacitors; and distributed capacitors between inductors coils will even be reaction to impedance during high frequencies.
FKS COILS provides a broad array of inductors such as: Shielded and Unshielded Power Inductors, High Voltage Power Inductors, Coupled Power Inductors, RF Inductors and so on. they are specifically designed for power converter, industrial, automotive, consumer electronic products, medical, new energy applications.
