Overview
The MLB03-400-RC is a multilayer ferrite bead manufactured by Allied Components International. It features a 0402 (1005 metric) surface-mount package and provides an output impedance of 40 ohms at its rated frequency. The component has a maximum DC resistance of 0.3 ohms and contains one functional element with two terminals. It is designed for high-frequency noise suppression in electronic circuits.
Feature Summary
- Multilayer construction for compact noise filtering
- High impedance characteristic for EMI suppression
- Surface-mount design for automated assembly
Applications
- High-speed data line filtering
- Power supply noise reduction
- RF circuit interference suppression
Procurement Notes
Verify the specific impedance frequency rating against application requirements, as ferrite beads exhibit frequency-dependent performance. Confirm the 0.3 ohm maximum DC resistance aligns with current handling needs. Ensure the 0402 package size fits the PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a low-profile, high-impedance filter is required for signal integrity. The 40 ohm impedance value targets specific noise frequencies. Consider the 0.3 ohm DC resistance impact on voltage drop. The multilayer technology offers reliability in space-constrained designs compared to wound alternatives.
Part Context
This ferrite bead belongs to the MLB series from Allied Components International, which focuses on passive components for signal conditioning. The 0402 footprint is standard for dense PCB layouts. Ferrite beads in this category are essential for maintaining signal quality in digital and RF applications by attenuating unwanted high-frequency noise.
