MLB03-481-RC

Overview

The MLB03-481-RC is a multilayer ferrite bead manufactured by Allied Components International, designed for high-frequency noise suppression in compact electronic circuits. This component features a single-line configuration housed in a standard 0402 surface-mount package, facilitating automated assembly and space-constrained designs. It exhibits an impedance of 480 ohms at a frequency of 100 MHz, providing effective attenuation of electromagnetic interference in the specified range. The device maintains a DC resistance of 800 milliohms, ensuring minimal signal loss and voltage drop during normal operation. These electrical characteristics define its performance profile for filtering applications.

Feature Summary

• Multilayer construction provides robust noise suppression capabilities within a small form factor
• Single-line design simplifies circuit integration for targeted frequency filtering
• Surface-mount packaging enables efficient placement on printed circuit boards

Applications

• High-speed data line filtering in portable consumer electronics
• Power supply noise reduction in compact embedded systems
• Electromagnetic interference suppression in communication modules

Procurement Notes

Verify that the received components match the MLB03-481-RC designation and confirm compliance with RoHS standards as indicated in official documentation. Ensure storage conditions prevent moisture absorption prior to soldering. Cross-reference part markings with manufacturer specifications to authenticate origin and avoid counterfeit substitutions during acquisition processes.

Selection Notes

Choose this component when a 0402 footprint is required for high-frequency noise control. The 480-ohm impedance at 100 MHz suits applications targeting specific RF interference bands. Consider the 800-milliohm DC resistance limit for current-carrying requirements. Evaluate spatial constraints against the single-line architecture to ensure compatibility with existing board layouts and signal integrity needs.

Part Context

This ferrite bead belongs to the MLB series of multilayer ceramic components produced by Allied Components International. The series focuses on providing passive filtering solutions for modern electronics where size and performance are critical. The model number indicates specific impedance and package dimensions, aligning with industry-standard sizing conventions for surface-mount technologies used in mass-produced devices.

Replacement Considerations

Consult official substitution lists from Allied Components International for verified equivalents. Ensure any alternative part matches the 0402 package, 480-ohm impedance at 100 MHz, and 800-milliohm DC resistance. Verify that substitute components maintain identical thermal and mechanical properties to preserve circuit reliability.
