BBUP00100505121Y00

Overview

The BBUP00100505121Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount technology applications. It features a 0402 (1005 metric) package with dimensions of 1 mm in length, 0.5 mm in width, and 0.5 mm in height. The component provides an impedance of 120 ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 2 A and maintains a maximum DC resistance of 0.055 ohms. The device operates within a temperature range of -55°C to +125°C and includes shielding to minimize electromagnetic interference.

Feature Summary

• Shielded construction to reduce electromagnetic interference
• Multilayer ferrite chip bead design for high-frequency noise suppression
• Surface-mount compatibility with standard SMD/SMT termination types

Applications

• High-frequency noise filtering in electronic circuits
• Signal integrity enhancement in compact PCB layouts
• EMI suppression in portable electronic devices

Procurement Notes

Verify the specific electrical parameters against the official Pulse Electronics datasheet prior to procurement. Confirm that the impedance value of 120 ohms and maximum DC current rating of 2 A align with the target circuit requirements. Ensure the 0402 package size fits the designated footprint on the printed circuit board. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a shielded ferrite bead with 120 ohms impedance at 100 MHz is required in a 0402 package. Consider the 2 A current rating and low DC resistance for power line filtering applications. Evaluate the operating temperature range of -55°C to +125°C against the environmental conditions of the end-use product. Compare against other series variants if different impedance or current specifications are needed.

Part Context

This part belongs to the BBUP series of multilayer ferrite chip beads from Pulse Electronics. It shares the 0402 form factor common across several Pulse ferrite bead families but is distinguished by its specific 120 ohm impedance and 2 A current handling capability. The series is designed for general-purpose EMI suppression in space-constrained surface-mount designs.
