Working Principle

The W2F11A4718AT1A is a two-shell enclosure that houses a discrete capacitor element. The capacitor element is composed of two discrete dielectric layers, each with an internal and external surface. When an alternating current is applied to the device, it forms an electric double layer on the internal and external surfaces of the dielectric layers. This electric double layer then acts as a barrier to prevent noise and other interfering signals from entering the circuit, providing power supply noise, EMI/RFI filtering, and signal integrity improvement.

In addition to the capacitor element, the unit also includes a filter network to provide additional suppression of unwanted frequencies. This allows the device to filter out low-frequency noise from power supplies, as well as high-frequency noise, such as radio frequency interference, from other external sources. The device is protected from mechanical damage with a metal housing, which also protects against environmental factors. Overall, the W2F11A4718AT1A is a specialized device designed to provide excellent EMI/RFI filtering and signal integrity for a wide range of applications.
