Common mode chokes, or differential mode chokes, are used to provide a measure of electromagnetic interference (EMI) suppression. They couple AC current along the ground connection, allowing an AC component to pass while blocking DC. This reduces the amount of noise produced in an electrical system. The TF1821VU-502Y1R0-01 is a common mode choke from Coilcraft with excellent characteristics, making it suitable for a wide range of applications.

The device is constructed on an epoxy ferrite toroid, which provides high efficiency and a low-cost solution. Its design utilizes high-Q ferrite material to ensure low insertion losses and high immunity to stray magnetic fields. The excellent solderability of the ferrite material also results in a robust connection between the core and the copper winding.

The TF1821VU-502Y1R0-01 is a multipurpose, low-profile choke with a 20A AC rating and a 12mOhm DC impedance. Its operating frequency is up to 6MHz, suitable for most applications such as audio, low-voltage power supplies, and communication electronics where produced EMI must be suppressed. It is a high temperature, lead-free, molded choke with an operating temperature range from -40°C to +105°C.

The winding configuration of the TF1821VU-502Y1R0-01 is arranged such that a single inductor provides both common mode and differential mode suppression. The differential mode inductance of the device is 1.25mH. This prevents any differential mode current from flowing between the two lines which can cause interference. The inductance also provides a wide range of attenuation values, up to 50 dB in the higher frequency ranges.

The common mode choke of the TF1821VU-502Y1R0-01 works on the principle that any injected AC current on the line will be coupled onto the ground line, while suppressing the return current which keeps the DC retarded. Since the AC current has no direction, it can pass through the choke in either direction. This effectively reduces the amount of EMI produced in the system.

The TF1821VU-502Y1R0-01 is thus a versatile and effective solution for EMI suppression for a wide range of applications where differential and common mode interference suppression is required. Its versatile design ensures low insertion losses, high attenuation values, and tight winding tolerance, making it an ideal choice for a wide range of applications.
