Overview
The CTWBF-3.0 is a wide band choke ferrite bead manufactured by Central Technologies. It features an axial leaded configuration designed for electromagnetic interference suppression. The component provides an impedance of 550 Ohms at a frequency of 100 MHz. This specific part number denotes the standard axial variant, distinct from radial or surface-mount alternatives within the same product family.
Feature Summary
- Wide band choke functionality for noise suppression
- Axial leaded package construction
Applications
- Electromagnetic interference filtering in electronic circuits
- Signal line noise reduction
- Power supply ripple attenuation
Procurement Notes
Verify the lead configuration matches the design requirements, as datasheets may list both axial and radial variants under similar naming conventions. Confirm the impedance specification of 550 Ohms at 100 MHz aligns with the target frequency range. Ensure the manufacturer is identified as Central Technologies to distinguish from other ferrite bead suppliers offering similar values.
Selection Notes
Select this component when axial mounting is required for wideband noise suppression. Compare the 550 Ohm impedance against circuit requirements to ensure effective attenuation at 100 MHz. Consider physical size constraints associated with axial leads versus alternative radial or surface mount packages available from the manufacturer.
Part Context
This component belongs to the wide band choke category produced by Central Technologies. It serves as a passive filter element to suppress high-frequency noise. The axial form factor distinguishes it from radial versions like the CTWBF-3.0-S, which offers different impedance characteristics and mounting styles.
Replacement Considerations
Direct substitutes include the CTWBF-3.0-S if radial mounting is acceptable, though impedance differs significantly at 1.14 kOhms. Verify that any replacement maintains the 550 Ohm @ 100 MHz specification and axial lead style to ensure mechanical and electrical compatibility.
