Overview
The CT0201LSF-56NJ is a surface-mount wirewound inductor manufactured by Central Technologies. It features a ferromagnetic core and offers an inductance of 56 nH with a tolerance of ±5%. The component exhibits a DC resistance of 0.13 Ω and a self-resonant frequency of 2 MHz. It supports a maximum current rating of 750 mA and operates within a temperature range of -25°C to +105°C.
Feature Summary
- Utilizes a wirewound construction on a ferromagnetic core for stable inductance characteristics
- Designed for surface-mount assembly to facilitate automated PCB placement
- Provides high current handling capability suitable for power filtering applications
Applications
- RF circuit impedance matching networks
- DC-DC converter input or output filtering
- Signal line noise suppression in compact electronics
Procurement Notes
Verify the specific suffix 'N' and 'J' against the manufacturer's official documentation to confirm the exact inductance value, tolerance class, and packaging configuration. Ensure that the operating temperature range and current ratings align with the thermal design requirements of the target application before finalizing procurement orders.
Selection Notes
Select this component when a low-profile surface-mount form factor is required for high-frequency signal integrity. The 56 nH value and 750 mA current rating make it appropriate for space-constrained designs needing moderate inductance without excessive series resistance. Confirm compatibility with standard reflow soldering profiles.
Part Context
This part belongs to the CT0201LSF series of open-wire chip inductors from Central Technologies. These components are characterized by their small footprint and wirewound architecture, distinguishing them from multilayer ceramic variants. The series targets applications requiring precise inductance control in miniature electronic assemblies.
Replacement Considerations
Cross-reference with other 56 nH SMD wirewound inductors from Central Technologies or alternative manufacturers offering similar 0201 footprints. Verify that substitute parts match the 750 mA current rating and 2 MHz self-resonant frequency to maintain circuit performance.
FAQ
What is the self-resonant frequency of the CT0201LSF-56NJ?
The self-resonant frequency is specified as 2 MHz.
Does this inductor have a shielded case?
No, the CT0201LSF series utilizes an open-wire wound construction without magnetic shielding.
