MPZ1608S601ATA00 Overview
A ferrite bead is a passive electromagnetic interference (EMI) suppression component that combines a ferrite material with conductor windings. In the frequency domain, ferrite beads exhibit high AC impedance to attenuate high-frequency noise while passing DC current with minimal loss. As a category, ferrite beads sit within the broader hierarchy of EMI suppression components, alongside common-mode chokes, EMI filters, and LC filters, and are sub-categorized as either signal-line or power-line variants. Power-line ferrite beads such as the MPZ1608 series are optimized for higher current handling and lower DC resistance compared to signal-line parts.
Key specifications include 600 Ω ±25% impedance at 100 MHz, a 1 A rated current, 150 mΩ maximum DC resistance, and an operating temperature range of -55 °C to +125 °C. The 0603 footprint (1.6 mm × 0.8 mm × 0.8 mm) supports dense PCB layouts, while the surface-mount termination enables standard reflow soldering. According to the TDK catalog, the MPZ series targets countermeasures against everything from general signals to high-speed signal lines, offering various frequency characteristics across five different ferrite materials.
Technically, the MPZ1608S601ATA00 uses TDK's high-frequency ferrite material that exhibits peak impedance in the 100 MHz region with gradual roll-off, suppressing conducted EMI on power rails feeding microcontrollers, FPGAs, and switching regulators. Its low DCR minimizes the voltage drop across the bead, preserving regulation accuracy on high-current supplies.
Typical applications include DC power line filtering in portable devices, USB and HDMI interface filtering, smartphone RF module decoupling, and noise suppression on switching regulator outputs. In automotive infotainment and industrial control, similar parts (automotive-grade MPZ1608S601ATD25) are used.
When designing with this bead, place it as close as possible to the IC power pin or connector to maximize noise suppression effectiveness. Ensure the rated current (1 A) is not exceeded under worst-case load, as saturation will reduce impedance and noise attenuation.

Typical Applications
MPZ1608S601ATA00 is suitable for 6 applications: DC Power Line EMI Filtering, USB 2.0 High-Speed Data Line Filtering, Smartphone RF Module Decoupling, Switching Regulator Output Filtering, FPGA / Microcontroller Power Rail Decoupling, HDMI / DisplayPort Interface Power Filtering.
DC Power Line EMI Filtering
The MPZ1608S601ATA00 placed in series with a 3.3 V or 5 V DC supply suppresses conducted high-frequency noise from switching regulators and digital ICs. Its 600 Ω impedance at 100 MHz attenuates switching harmonics from buck converters operating at 1-4 MHz whose fundamental and harmonics extend into the 100 MHz region. The 1 A current capability and 150 mΩ maximum DCR keep voltage drop below 150 mV at full load, preserving regulator accuracy on high-current loads such as microcontrollers and FPGAs.
Recommended
USB 2.0 High-Speed Data Line Filtering
The MPZ1608S601ATA00 in series with USB VBUS (5 V) lines attenuates EMI from upstream switching converters that could otherwise couple into downstream USB transceivers and degrade signal integrity. Although USB data lines themselves use common-mode chokes, the 5 V VBUS rail benefits from this bead's 600 Ω @ 100 MHz impedance to suppress noise that may conduct into cable shielding. The 0603 footprint fits standard mobile and consumer layouts where USB VBUS traces are kept short.
Recommended
Smartphone RF Module Decoupling
Mobile handset designs use the MPZ1608S601ATA00 to decouple RF power amplifiers, transceivers, and baseband supplies in 0603 land-pattern PCBs. The 600 Ω @ 100 MHz impedance attenuates digital switching noise that would otherwise couple into sensitive RF blocks and degrade phase-noise and EVM performance. The 1 A current capability supports PA supply rails, and the 0.8 mm height accommodates ultra-thin smartphone enclosures. TDK's high-saturation ferrite material maintains impedance at full PA load current.
Recommended
Switching Regulator Output Filtering
Placed at the output of a buck or boost converter, the MPZ1608S601ATA00 suppresses residual switching ripple and high-frequency harmonics that bypass the LC output filter. With 600 Ω @ 100 MHz impedance it adds 30-40 dB of attenuation in the 100-300 MHz band where SMPS spectral noise is most concentrated. The 150 mΩ maximum DCR contributes less than 1% loss at 1 A load, making it transparent in efficiency calculations yet effective as a post-filter.
Recommended
FPGA / Microcontroller Power Rail Decoupling
The MPZ1608S601ATA00 complements bulk-decoupling capacitors on FPGA core and I/O rails by suppressing mid-frequency noise (10 MHz - 1 GHz) that ceramic capacitors cannot attenuate due to self-resonance. In designs with Xilinx or Altera FPGAs, placing the bead between the regulator output and the FPGA's power pins reduces conducted emissions that can radiate from cables and enclosure openings. The 1 A continuous rating covers most individual FPGA supply rails.
Recommended
HDMI / DisplayPort Interface Power Filtering
HDMI and DisplayPort transmitters in TVs, monitors, and set-top boxes use the MPZ1608S601ATA00 on the +5 V interface rail to suppress noise from upstream switching converters that could couple into the TMDS/aux lines. The 600 Ω @ 100 MHz impedance covers the 100-1000 MHz band where high-speed serializer noise is concentrated. The 0603 footprint matches typical HDMI front-end layouts and the 1 A rating handles hot-plug inrush.

Key Differentiators
- Power-line grade with 1 A continuous current (vs MMZ1608S601ATA00)
- Automotive-grade drop-in option available (vs MPZ1608S601ATD25)
- Lower DCR than typical signal-line equivalents (vs MMZ1608S601ATA00)
Design Notes
Place the MPZ1608S601ATA00 as close as physically possible to the IC power pin or connector that requires noise suppression. Maximum effectiveness is achieved when the bead sits within 5 mm of the load; distance from the source does not matter as much. Keep input and output traces separated to avoid coupling the unfiltered source around the bead through near-field coupling or trace capacitance.
Estimated: at full 1 A load with maximum DCR of 150 mΩ, the bead dissipates I²R = 1.0 × 0.150 = 0.150 W. In an 0603 footprint the part self-heats ~30-50 °C above ambient under this condition, well within the 125 °C operating limit. For continuous operation at the full 1 A rating, derate by 25% (use at ≤ 0.75 A) in enclosed housings above 70 °C ambient.
Do not exceed the 1 A rated current - saturation of the ferrite material dramatically reduces impedance and eliminates noise attenuation. Avoid placing the bead in parallel with a bypass capacitor across a low-impedance rail, as this creates a divider where the capacitor short-circuits high frequencies and defeats the purpose. Use the bead in series only. For bidirectional filtering on differential pairs use common-mode chokes instead.
