Additional Details

The ACM12V-701-2PL-TL01 is constructed with a ferrite core and wound with two identical coils, which are configured to cancel out differential mode signals while attenuating common mode noise. This configuration ensures that the desired signal passes through with minimal distortion, while the unwanted noise is effectively filtered. The choke's performance is characterized by its common mode impedance, differential mode impedance, and rated current. These parameters are crucial for selecting the appropriate choke for a specific application. The ACM12V series is designed for use in a wide range of applications, including consumer electronics, industrial equipment, and automotive systems. TDK's expertise in materials and manufacturing ensures that these chokes offer reliable and consistent performance. Proper application and circuit design are essential to maximizing the effectiveness of the common mode choke. Designers should carefully consider the frequency range of the noise to be suppressed, the impedance characteristics of the choke, and the current requirements of the circuit.
