TDK’s MPZ Series ferrite chip beads are used to suppress noise in both signal and power supply circuits. They are effective at reducing noise simply by being
placed into the circuit in series. Multilayer chip beads consist of ferrite material and a conductive paste layered together. The equivalent circuit diagram of a chip
bead consists of a reactance component, X, and a resistive component, R. The combined impedance of X and R is denoted as impedance Z. The static
characteristics of a chip bead are typically described as the impedance value Z at a frequency of 100MHz. While several different chip beads could have the
same impedance value at 100MHz, it is important to look at their individual frequency characteristics to determine which bead will work best for the circuit within
the required frequency range. TDK offers up to five material types which provide various frequency characteristics for MPZ series chip beads in a variety of case
sizes, each suited to different applications. Availability of materials varies with case size.
