UCB15-121T-RC

Overview

The UCB15-121T-RC is a single-line ferrite bead manufactured by Allied Components International, designed for surface-mount applications. It utilizes an 0806 package configuration to provide compact noise suppression capabilities in electronic circuits. The component exhibits a nominal impedance of 120 ohms at its specified test frequency, ensuring effective attenuation of high-frequency electromagnetic interference signals. It features a low direct current resistance (DCR) of 20 milliohms, which minimizes power loss and voltage drop when conducting steady-state currents. This combination of impedance characteristics and low resistive loss makes it suitable for filtering applications where signal integrity must be maintained while suppressing unwanted noise.

Feature Summary

• Provides single-line noise suppression through ferrite material properties
• Designed for surface-mount technology integration using standard footprints
• Maintains low DC resistance to minimize insertion loss in power lines

Applications

• High-frequency noise filtering on data lines
• Power supply line decoupling in portable devices
• Electromagnetic interference suppression in consumer electronics

Procurement Notes

Verify the manufacturer datasheet for specific impedance tolerance ranges and maximum current ratings before finalizing design integration. Confirm that the 0806 package dimensions align with your PCB layout constraints. Ensure compliance with RoHS directives if required by your regional regulations. Cross-reference the part number suffix to confirm the reel quantity and tape-and-reel specifications match your assembly equipment requirements.

Selection Notes

Select this component when a balance between moderate impedance and minimal DC resistance is required for single-channel filtering. The 0806 form factor offers a compromise between thermal performance and board space efficiency compared to smaller packages. Consider the operating temperature range and saturation current characteristics relative to your circuit's peak load conditions to ensure stable performance under varying electrical stresses.

Part Context

This component belongs to the Ultra Current Bead series from Allied Components International, which focuses on providing cost-effective noise suppression solutions. The UCB15 series typically targets general-purpose electronic applications requiring reliable EMI/RFI mitigation. It serves as a passive filter element within larger systems, complementing other components like capacitors and inductors to achieve comprehensive signal integrity management.

Replacement Considerations

Direct substitutes may include other 0806 ferrite beads with similar 120-ohm impedance and comparable DCR values. Verify pin compatibility and physical footprint adherence when considering alternatives from different manufacturers. Ensure that any replacement maintains equivalent thermal and electrical performance characteristics to avoid redesign efforts.
