Overview
The KEMET B-01-RTSF is a shielded ferrite bead featuring an axial bead lead termination. It exhibits a DC resistance of 2 ohms and supports a maximum DC current of 5 amperes. The component operates within a temperature range of -20°C to +70°C. Physical dimensions include a diameter of 3.4 mm and a length of 67 mm for the standard B-01 variant, while the RTSF suffix indicates specific packaging or material variations such as ammo pack availability.
Feature Summary
- Shielded construction to minimize electromagnetic interference
- Axial bead lead termination for through-hole mounting
- High current handling capability up to 5A
Applications
- Power supply input filtering
- DC line noise suppression
- Electromagnetic compatibility (EMC) improvement in electronic circuits
Procurement Notes
Verify the exact physical dimensions and packaging type against the specific datasheet revision, as the RTSF suffix may denote specific bulk or ammo pack configurations distinct from standard variants. Confirm RoHS compliance status and ensure the operating temperature range meets the application requirements before finalizing procurement specifications.
Selection Notes
Select this component when high DC current capacity is required alongside significant impedance characteristics. Ensure the axial lead form factor fits the PCB layout constraints. Compare the 2-ohm DC resistance against circuit power loss requirements and verify that the 5A rating exceeds the maximum expected load current under all operating conditions.
Part Context
This part belongs to the KEMET B-01 series of ferrite beads, designed for general-purpose noise suppression. The series offers various impedance and current ratings, with the B-01-RTSF specifically providing a balance of low DC resistance and high current tolerance suitable for power rail protection.
Replacement Considerations
Cross-reference with other KEMET B-01 series variants for different impedance values. Verify mechanical fit and electrical parameters against competitor axial ferrite beads if sourcing alternatives.
