Ferrite Beads and Chips

Ferrite beads and chips are passive components used to filter out high frequency noise in electronic systems. The LI0805H400R-10 is a ferrite bead/chip developed by the Laird Performance Materials Division. It is a 0805 size surface mount, high grade, non-shielded power inductor. This component is ideal for high frequency noise suppression and filtering in digital and analog circuits.

Connection Options

The LI0805H400R-10 can be surface mount on either a printed circuit board or a ferrite board. When mounting this component, use gold or tinned pads on the printed circuit board to prevent contact resistance and thermal stress problems. On the ferrite board, use either gold or silver pad so that the component can be contact soldered. If the component is mounted on a non-conductive surface such as plastic, use a conductive adhesive to close the electrical connection.

Features & Benefits

The LI0805H400R-10 provides robust performance in high frequency applications. It has a low profile of 0.4mm and its inductance range can reach up to 4nH. The core material of this component is ferrite powder, which provides an improved temperature stability over traditional ferrites. For high speed digital applications, the 10 ohm AU resistive material provides superior temperature and environmental stability over traditional base ferrite materials. The LI0805H400R-10\'s low profile, high quality construction and optimized performance make it a great choice for high speed digital circuits. This ferrite bead/chip will help prevent interference and keep the electronics of the system running smoothly.

Application Fields & Working Principle

The LI0805H400R-10 can be used in a variety of applications including high speed digital circuits, mobile phones, tablets, and consumer electronics. This component is ideal for any application where high frequency noise suppression is necessary. The working principle of this component is based on the fact that ferrite is an electromagnetic material. It acts as a high frequency noise filter by suppressing high frequency noise and preventing it from traveling through the attached circuitry. The working principle of ferrite beads/chips is based on impedance, a quantity which provides a measure of the opposition that a circuit presents to the flow of an alternating current. By carefully selecting the right material and adjustment of the components, a suitable impedance can be achieved to suppress the high frequency noise. It is important to choose the right material and components to ensure the desired performance. The LI0805H400R-10 is designed to provide superior performance in suppressing high frequency noise. Its inductance range of up to 4nH provides maximum reach in suppressing high frequency noise. The 10 ohm AU resistive material further improves the performance by providing additional temperature and environmental stability. The low profile and optimized construction makes this component ideal for use in high speed digital applications.
