Common mode chokes are electrical filters which are used to block high frequency noise that can appear in two-wire transmission lines. The B82505WA7 is a part of a range of common mode chokes from Semtech Corporation. It is a high-frequency, wide-band, surface mount common mode inductor, and it provides good noise suppression over a range of frequency bands. The B82505WA7 has a self-resonant frequency of 10GHz, and it is designed to be used in power electronics applications.

The principle of operation for the B82505WA7 is that it blocks high frequency noise from the two-wire transmission line in order to reduce interference and noise pickup. It creates an inductive field around the two wires which acts as a barrier, preventing the noise from passing through. The field is also created in a way that it enables transmission of the desired signal while blocking the high frequency interference. The choke is also able to filter out noise generated from electromagnetic interference (EMI) sources, such as motors, generators, computers, cell phones, and other electronic devices.

The B82505WA7 is designed for use in a variety of applications, including telecommunication, computer, industrial, consumer, automotive, transportation, and power electronics. It is suitable for use in high speed digital signal processing (DSP) devices, such as digital picture frames, set-top boxes, and industrial control systems, as well as high speed analog signals, such as RF and microwave signals. It can also be used to reduce EMI caused by inverters, motors, and other sources of electrical noise.

The B82505WA7 is available in a wide range of sizes, from 1.2mm x 0.5mm to 7.0mm x 7.0mm, and can support current carrying capacities of up to 1.5A. It is rated to operate at temperatures ranging from -55°C to +150°C. The device also has black epoxy coatings, which provide shielding from environmental elements and enhance the EMI suppression capabilities of the device.

The B82505WA7 common mode inductor from Semtech Corporation is an effective device for EMI suppression in a variety of applications. It is easy to use, requires minimal board space, and is able to provide superior noise suppression over a wide range of frequency bands.
