Overview
The BBUP00201209121Y00 is a shielded multilayer ferrite chip bead from the Pulse Electronics BBUP series, designed for surface-mount applications. It features an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current rating of 5 A and has a maximum DC resistance of 20 mOhms. It operates within a temperature range of -55°C to +125°C and utilizes a 0805 (2012 Metric) package measuring 2 mm in length, 1.2 mm in width, and 0.9 mm in height.
Feature Summary
- Shielded construction to minimize electromagnetic interference
- Multilayer ferrite technology for compact integration
- High current handling capability suitable for power lines
Applications
- DC power line filtering
- EMI suppression in portable devices
- Signal integrity enhancement in high-speed circuits
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before procurement, as variations may exist between distributors. Confirm the package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status if required by regulatory standards.
Selection Notes
Select this component when a low-profile, shielded ferrite bead is required for high-current applications. The 0805 package offers a balance between size and current capacity. Consider the 120 Ohm impedance profile for the specific noise frequencies targeted in the design. Ensure the 5 A current rating exceeds the maximum expected load current to prevent saturation or excessive heating.
Part Context
This part belongs to the BBUP series of EMI suppression ferrite chip beads from Pulse Electronics. The series provides a wide impedance range and supports currents up to 6 A. These components are engineered for SMD/SMT mounting and are commonly used in consumer electronics and industrial equipment where space constraints and noise reduction are critical design factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers by matching impedance, current rating, and physical dimensions.
