Fixed Inductors Procurement Notes

Verify the specific tolerance suffix when ordering, as the base part number may require explicit designation for the ±2% variant. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the 0805 footprint matches the target PCB design. Cross-reference datasheet parameters against system requirements before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component for applications requiring precise low-inductance values with minimal deviation. The high Q-factor and SRF make it suitable for RF filtering. Compare the 0.3 A current rating against peak load conditions. Consider the 0805 size constraints relative to available board space. Evaluate thermal management needs given the 125 °C maximum operating temperature limit.

Fixed Inductors Part Context

This part belongs to the CT0805HTF series of wire-wound chip inductors manufactured by Central Technologies. The series offers a wide range of inductance values from 1.8 nH to 1000 nH in the 0805 surface mount package. These components are characterized by their ceramic core construction and compliance with RoHS standards, targeting general electronic and RF markets.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CT0805HTF-R33G (33 nH) or CT0805HTF-R47G (47 nH) if slight inductance variations are acceptable. Verify that any replacement maintains the ±2% tolerance and identical package dimensions. Check for equivalent current ratings and self-resonant frequencies to ensure circuit compatibility.
