- Power supply input/output filtering applications
Procurement Notes
Verify the specific manufacturer datasheet for the B-02-RT model to confirm exact electrical characteristics and mechanical dimensions. Ensure compatibility with your PCB footprint design, as bead lead components require specific soldering techniques. Confirm that the 5A current rating and 4 Ohm resistance meet your circuit requirements before finalizing procurement decisions.
Selection Notes
Select this component when a simple, cost-effective solution for common mode noise suppression is required. The 4 Ohm resistance value suggests suitability for lines where minimal voltage drop is acceptable alongside attenuation. Consider the physical size and lead configuration to ensure it fits within the available space on the target printed circuit board layout without obstructing other components.
Part Context
This part is manufactured by KEMET, a provider of passive electronic components. Ferrite beads like the B-02-RT are widely used across various industries to mitigate radio frequency interference. They function by dissipating high-frequency energy as heat, thereby cleaning up signal integrity in sensitive electronic systems without significantly affecting low-frequency or DC signals.
