B82721X0001

EMI filters are electrical noise suppression devices used to reduce EMI (electromagnetic interference) between electronic components, such as in power line cable wiring. The B82721X0001 is a series of EMI filters, specifically a set of four separate filter kits. Each kit has two layers of metal plates sandwiched between two fused glass insulators. Each of the layers are composed of spiral coils of ferrite cores, series capacitors, primary and secondary inductors, and finger stock contacts. These components, combined, form a two-node EMI filter with a typical attenuation of up to 18dB.

Working Principle of EMI Filters:

EMI filters help suppress EMI interference in power line cable wiring. It does so by allowing the electric current flow in one direction while blocking the current in the other direction. The filtering effect is due to the components that are connected together in the filter, such as the ferrite cores, series capacitors, primary and secondary inductors, and finger stock contacts. These components all have different characteristics that, when used in combination, can effectively reduce EMI interference.

Capacitors, for example, block or reduce the electric current in one direction while allowing it to flow in the other direction. Inductors, on the other hand, act as a higher-resistance circuit. As such, they reduce the electric current in both directions. The ferrite cores are often used as a shield, blocking the electric current and deflecting it away from the other components. Fused glass insulators protect the other components from damage due to electric shock. Finally, the finger stock contacts help maintain a secure connection between the components.

Once assembled, these components together form the two-node EMI filter, which helps reduce the amount of EMI interference that passes through the power line cable wiring. It also helps reduce the amount of noise generated from electronic devices and systems in operation. As such, it is a primary component in many electrical systems, and is used to help ensure the smooth operation of sensitive electronic components.

The B82721X0001 EMI filter kits offer an effective and economical solution to reduce EMI emissions and improve system performance. With up to 18dB of attenuation of EMI interference, these filter kits are designed to comply with the latest EMC standards. They also feature a slim construction, making them ideal for installation in cramped or restricted space.

In conclusion, the B82721X0001 EMI filter series provides a reliable and effective noise suppression solution for electronic systems. With its slim construction, these filter kits are suitable for a wide range of applications, offering superior levels of performance and protection. Thanks to their ability to reduce EMI interference, these filter kits are a great way to protect expensive electronic components from damage due to electromagnetic interference.
