Overview
The BBPY00453215700Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics. It features an 1812 (4532 metric) surface-mount package with shielded construction. The component provides an impedance of 70 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 6 A. Its maximum DC resistance is 30 mOhms, with a tolerance of 25%. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Shielded multilayer ferrite chip bead design for electromagnetic interference suppression
- High current handling capability suitable for power line applications
- Low DC resistance to minimize signal loss in high-current circuits
Applications
- Power supply output filtering
- DC-DC converter noise suppression
- High-speed digital circuit EMI mitigation
Procurement Notes
Verify the specific impedance value of 70 Ohms and the 6 A current rating against the official datasheet before integration. Confirm the 1812 package dimensions match the PCB footprint requirements. Ensure the operating temperature range of -55°C to +125°C meets the environmental specifications of the target application.
Selection Notes
Select this component when a shielded ferrite bead is required for high-current paths up to 6 A. The 1812 package offers a balance between current capacity and board space. Compare the 70 Ohm impedance against other series variants if different attenuation characteristics are needed for specific frequency bands.
Part Context
This part belongs to the BBPY series of shielded ferrite beads from Pulse Electronics. It shares the 1812 form factor with other high-current variants but differs in impedance ratings. The series is designed for robust EMI suppression in compact electronic designs requiring reliable performance under varying thermal conditions.
Replacement Considerations
Cross-reference with other BBPY series parts sharing the 1812 package and similar current ratings. Verify that substitute components maintain the same shielding type and impedance profile to ensure equivalent circuit performance.
