1. Chip magnetic beads.
Chip beads are surface-mount components that are suitable for high-frequency, high-frequency noise suppression and filtering of power lines. It is made of ferrite material and has the characteristics of high resistivity and low inductance. Chip beads are used primarily to filter and suppress noise in circuits.
The characteristics of chip beads are as follows:
1.Excellent high-frequency performance: Chip beads have high resistivity and low inductance, so they can effectively suppress high-frequency noise.
2.Low temperature coefficient: Chip beads have a small temperature coefficient, so their performance is less affected by temperature.
3.Small size: Chip beads are small and space-saving, making them suitable for surface mount technology.
4.Easy installation: Chip beads can be soldered directly or mounted on a circuit board for easy installation.
2. Chip inductance.
A chip inductor is a surface-mount component that is used in high-frequency, high-current power lines. It consists of a coil and a magnetic core, and is characterized by high inductance and low resistivity. Chip inductors mainly play the role of energy storage and filtering in circuits.
The characteristics of chip inductors are as follows:
1.High inductance: Chip inductors have a high inductance and are able to meet the needs of high-current power lines.
2.Low temperature coefficient: Chip inductors have a small temperature coefficient, so their performance is less affected by temperature.
3.Small size: Chip inductors are small in size, space-saving, and suitable for surface mount technology.
4.Easy to install: Chip inductors can be soldered directly or mounted on the circuit board for easy installation.
3. The difference between chip beads and chip inductors.
1.The structure is different: chip beads are made of ferrite material, while chip inductors are made up of coils and cores.
2.The functions are different: chip beads mainly play the role of filtering and suppressing noise, while chip inductors mainly play the role of energy storage and filtering.
3.Different performance: chip beads have the characteristics of excellent high-frequency performance, small temperature coefficient and small size, while chip inductors have the characteristics of high inductance, small temperature coefficient and small size.
4.Different applications: chip beads are suitable for high-frequency noise suppression and power line filtering, while chip inductors are suitable for high-frequency, high-current power lines.
Fourth, the selection method.
When selecting chip beads and chip inductors, the following factors need to be considered:
