Introduction

PMH0805-100 is part of the Ferrite Beads and Chips family, and is commonly used to provide characteristic impedance to PCB signal lines to reduce the transmission of high frequency noise radiation. It features an excellent noise suppressing capability over an extremely wide frequency range and has a wide variety of applications.

Application Fields

The PMH0805-100 has a multitude of uses and applications, almost all of which can be attributed to its noise suppressing capability. It provides excellent shielding performance in many fields, such as personal computers, mobile phones, televisions, digital cameras, musical instruments, PDA, and automotive electronics.

PMH0805-100 can be used to reduce EMI radiation to comply with FCC and CE regulations. It is also applicable for applications that required low Insertion Loss and High Current Capability.

Working Principle

PMH0805-100 contains a ferrite core, which consists of soft, ferrimagnetic material. It is wrapped with a wire coil to create a static magnetic field. The ferrite core has high magnetic permeability, which allows it to concentrate a large amount of magnetic flux. This flux creates a high magnetic field that acts like a shield against electromagnetic noise.

When external electromagnetic interference passes through the ferrite core, the eddy currents interact with the static magnetic field. These currents can be used to modulate the AC current, absorb the noise, and create a counter current. This process helps reduce the transmission of noise radiation from the PCB.

Advantages

PMH0805-100 has a number of advantages compared to other EMI shielding products. It is easy to install and does not require soldering, and has a high rated current and low Insertion Loss. It is small in size and has a wide frequency range, fromMHz up to GHz, which makes it suitable for a wide variety of applications.

The low cost and excellent shielding performance make PMH0805-100 an ideal solution for reducing EMI radiation. It is an ideal choice for most electronic devices, computers, and automotive electronics.

Conclusion

PMH0805-100 is a ferrite bead and chip, and is designed to provide excellent shielding performance for a wide range of applications. It is small in size, low-cost, easy to install, and has a high rated current and a wide frequency range. The PMH0805-100 is an ideal solution for reducing EMI radiation, and is an attractive choice for most electronic devices, computers, and automotive electronics.
