Common Mode Chokes are used for EMI (Electromagnetic Interference) suppression in a variety of environments. The UU9LFBNP-B163 is a specific type of EMI suppression developed by Vishay Intertechnology for use in cable-based electronic systems. The UU9LFBNP-B163 is commonly used in automotive, telecommunications, consumer electronics, and professional audio/video applications, as well as other applications requiring reliable electromagnetic compatibility (EMC) performance.

Unlike other suppression methods that rely on filtering, EMI suppression using common mode chokes can significantly reduce the overall system impedance and consequently reduce the insertion losses. This makes the UU9LFBNP-B163 a very effective form of EMI suppression in applications where traditional filtering methods are not feasible. This performance can be a key factor in reducing system interference and improving signal quality.

The UU9LFBNP-B163 is a high power common mode choke designed for use in balanced and differential line applications. It has an inductor with a wide range of inductance values from 0.05 µH to 1.1 µH. It is also capable of operating at a wide temperature range (from -40°C to +150°C). The UU9LFBNP-B163 has an epoxy-based encapsulation material that provides excellent thermal cycling, shock and vibration performance. It also features a robust construction that can withstand high mechanical stresses, and it is designed to meet UL 508A guidelines.

The UU9LFBNP-B163 works by suppressing common mode currents in the signal line. It does this by forming a loop between the two wire lines using an inductor housed inside the epoxy-based encapsulation material. This helps to reduce high frequency currents, resulting in lower levels of EMI interference. It also helps to reduce the total impedance of the signal line, which can result in better signal transmission quality. The inductance of the UU9LFBNP-B163 is adjustable, enabling the user to customize the device for specific applications.

The UU9LFBNP-B163 is designed for use in harsh environments and is well-suited for applications requiring extreme temperatures and high vibration levels, such as automotive, telecommunications, and professional audio/video. Its high power rating and robust construction makes it ideal for use in applications requiring high power EMI suppression. The UU9LFBNP-B163 is also an effective tool for reducing common mode noise and improving system signal quality.
