The MMZ1608R121ATA00 with TDK EMI Filter Beads, chips & arrays manufactured by TDK is a surface mount ferrite bead design that effectively suppresses electromagnetic interference. It consists of a ferrite bead, a dedicated element that suppresses both common-mode noise and normal-mode noise, a bypass capacitor, and a chip resistor. The ferrite bead attenuates both common-mode and normal-mode noise in the frequency range from 100MHz to 1GHz, while the bypass capacitor allows high-frequency current to bypass the part. The chip resistor reduces the inductance and impedance of the circuit. The part is RoHS compliant and features a low profile design. It is well-suited for a wide range of applications, including automotive, communications, consumer electronics, and industrial.
