MPZ-H Chip Beads TDK MPZ-H Chip Beads are large current / low DC-resistance chip beads, designed in a standard 0603 or 1005 package sizes. These halogen-free chip beads provide a noise-reduction solution for power lines, with models available whose impedance values range from 22Ω to 220Ω at 100MHz. This line of the MPZ series features a -55° to 125°C operating temperature range and a 50% resistance improvement over existing -C type counterparts. TDK MPZ-H chip beads are ideal for noise removal in mobile devices (smartphones/tablet terminals), PCs, recorders, and household appliances.
