Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm tolerance accuracy, as codes such as K denote ±10%. Ensure the procurement documentation explicitly references the Central Technologies datasheet for the CTS3F series to validate electrical parameters against the required design specifications before finalizing acquisition.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor is required for RF or power applications. The 18 µH value and 300 mA current rating suit moderate power levels. Verify that the 0.89 Ω DCR aligns with efficiency requirements and that the 45 MHz SRF exceeds the target operating frequency to prevent resonance issues.

Fixed Inductors Part Context

This part belongs to the CTS3F series of shielded inductors manufactured by Central Technologies. The series offers various inductance values with axial leads, providing a standardized solution for through-hole designs requiring magnetic shielding. The CTS3F-180K specifically addresses needs for 18 µH inductance within this product family.

Fixed Inductors Replacement Considerations

Cross-reference other CTS3F series variants for different inductance values. No direct substitute part numbers are confirmed in public documentation. Ensure any replacement matches the 18 µH nominal value, 300 mA current rating, and axial package dimensions.
