MPZ-E AEC-Q200 Qualified Ferrite Beads TDK MPZ-E AEC-Q200 Qualified Ferrite Beads attain high impedance at GHZ bands compared to the MPZ series. TDK MPZ-E also offers low direct current resistance, providing compatibility with large currents and supporting low power consumption. MPZ-E ferrite beads perform will even in signal lines requiring low direct current resistance. The series provides 220Ω or 120Ω impedance at 100MHz and operates over a -55°C to +125°C operating temperature range.
