Ferrite Beads and Chips encompass a wide range of electrical components used for filtering in electrical systems. Often used in radio frequency (RF) circuits, they are available in a variety of shapes, sizes, and performance specifications. One example of a ferrite chip is PMH1812-900. This chip is typically used in mobile devices, such as cell phones, and for RF power amplifiers in radar systems. In this article, we will discuss the application field and working principle of PMH1812-900.

PMH1812-900 is a multi-layer ferrite chip designed for high frequency applications. It is composed of four layers of ferrite material, with two inner layers of active material and two outer layers of isolation material. This chip has excellent low-profile capabilities and excellent high-frequency suppression capabilities. It is able to extend the frequency range to 35 MHz and reduce the size of the filter effectively.

The application field of PMH1812-900 includes various electronic devices such as mobile phones, tablet computers, Bluetooth devices, wireless routers, and electron guns. In these applications, PMH1812-900 ferrite chips help reduce the amount of spurious noise in the system and suppress electromagnetic radiation. It is also used in automotive applications to reduce interference levels. Additionally, it can be used in medical equipment to help minimize the effects of electromagnetic interference.

PMH1812-900 ferrite chips work by forming an inductive reactance in series with the load. This inductive reactance causes a frequency-dependent reduction in the amount of current flow, thus attenuating high-frequency noise. The circuit design can be optimized to eliminate any undesirable signal components and to ensure a high signal-to-noise ratio.

In summary, PMH1812-900 ferrite chips are used in a wide range of applications, such as mobile devices, automotive applications, and medical equipment. The chip design features two inner layers of active material and two outer layers of isolation material. This design helps reduce the amount of spurious noise in the system and suppress electromagnetic radiation. Moreover, the chip is able to extend the frequency range to 35 MHz and reduce the size of the filter effectively.
