Overview
The CT0201LSF-28NJ is a fixed wirewound inductor manufactured by Central Technologies, designed for surface-mount applications. It features an inductance value of 28 nH with a tolerance of ±5%. The component exhibits a DC resistance (DCR) of 200 mΩ and operates within a temperature range of -25°C to +105°C. Its self-resonant frequency is specified at 2.4 GHz. The physical dimensions are approximately 0.46 × 0.58 × 0.45 mm, classifying it as a compact SMD power inductor suitable for high-frequency circuits.
Feature Summary
- Wirewound construction utilizing a ferromagnetic core for stable inductance performance
- Surface-mount design optimized for automated assembly processes
- Shielded structure to minimize electromagnetic interference in dense layouts
Applications
- RF signal filtering in communication modules
- Power supply input/output stages for high-frequency converters
- Impedance matching networks in wireless transmission devices
Procurement Notes
Verify the specific datasheet version from Central Technologies to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with standard reflow soldering profiles for 0201 packages. Cross-reference part numbers to distinguish between shielded and unshielded variants within the same series, as functional differences may exist despite similar naming conventions.
Selection Notes
Select this component when ultra-low inductance values are required for high-speed digital or RF applications. The 28 nH rating suits scenarios demanding minimal impedance at operating frequencies. Consider the 200 mΩ DCR for efficiency constraints and verify that the 2.4 GHz self-resonant frequency aligns with the target circuit bandwidth to avoid parasitic resonance issues.
Part Context
This part belongs to the CT0201LSF series of surface-mount power inductors from Central Technologies. The series offers various inductance values tailored for different frequency ranges. The 'LSF' designation typically indicates a shielded wirewound construction, distinguishing it from open-core alternatives like the CT0201CSF series, which may exhibit different magnetic field leakage characteristics.
Replacement Considerations
Direct substitutes include other 28 nH ±5% inductors in 0201 packages with comparable DCR and SRF ratings. Verify pinout and mechanical footprint compatibility before integration. Alternative series from the same manufacturer should be evaluated based on specific thermal and current handling requirements.
