- High-frequency signal processing
Procurement Notes
Verify the specific datasheet version for the CT0402CSF-22NJ to confirm exact electrical parameters, as self-resonant frequency specifications may vary between sources. Ensure compatibility with your PCB footprint and reflow soldering profile. Check for RoHS compliance status if required by your manufacturing standards. Confirm that the 375 mA current rating meets your application's peak load requirements without saturation.
Selection Notes
Select this component when a low-inductance value near 22 nH is required for high-frequency applications. Consider the 0.36 Ω DC resistance impact on power loss. Evaluate the 2 MHz self-resonant frequency against your operating frequency to ensure effective inductive behavior. Compare the 375 mA current rating with your circuit's maximum current draw to prevent saturation or overheating issues during operation.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series offers various inductance values in the 0402 package size. These components are designed for general-purpose use in consumer electronics and communication devices where space constraints and high-frequency performance are critical factors in the design process.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-reference inductance, tolerance, current rating, and SRF when evaluating alternatives.
