ACM1211-701-2PL-TL – TDK

Overview

The TDK ACM1211-701-2PL-TL is a high-performance, 2-channel common mode choke designed for robust noise suppression in power delivery networks. Its primary function is to attenuate differential-mode noise while allowing desired differential-mode signals to pass, a critical task in maintaining signal integrity. A key design consideration for such components is the trade-off between high impedance at the target frequency and low DC resistance (DCR) to minimize power loss and heat generation; the ACM1211-701-2PL-TL achieves an excellent balance with its 700 Ohm impedance at 100 MHz and a mere 6 mOhms DCR, ensuring efficient operation without compromising filtering effectiveness.
