Overview
The BBBK00201209471Y00 is a shielded surface-mount ferrite bead manufactured by Pulse Electronics. It features an impedance of 470 Ohms with a 25% tolerance and a maximum DC resistance of 400 mOhms. The component supports a maximum current of 300 mA and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2 mm in length, 1.25 mm in width, and 0.9 mm in height.
Feature Summary
- Shielded construction for electromagnetic interference suppression
- Surface-mount design for automated PCB assembly
- Wide operating temperature range suitable for harsh environments
Applications
- High-frequency noise filtering in electronic circuits
- Signal integrity protection in data lines
- Power supply decoupling applications
Procurement Notes
Verify the manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the specified impedance and current ratings align with your circuit requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure storage conditions maintain component integrity prior to assembly.
Selection Notes
Select this component when a compact, shielded ferrite bead is required for high-frequency noise attenuation. The 470 Ohm impedance value targets specific noise frequencies. The 300 mA current rating must exceed the maximum DC current in the application line. The small 0603 footprint is suitable for space-constrained designs requiring reliable EMI suppression.
Part Context
This component belongs to the BBBK series of ferrite beads from Pulse Electronics. The series offers various impedance values and current ratings in standard surface-mount packages. These components are designed for general-purpose EMI suppression in consumer electronics and industrial equipment where space is limited.
Replacement Considerations
Consult official distributor databases for cross-reference part numbers. Verify that any substitute matches the 470 Ohm impedance, 300 mA current rating, and 0603 package dimensions. Ensure the replacement component also provides shielding and meets the same temperature specifications.
