Fixed Inductors Procurement Notes
Verify the specific suffix 'TF' indicates RoHS compliance as per manufacturer documentation. Confirm that the 700 mA rating aligns with your system's thermal requirements. Ensure the 470 mOhm DC resistance meets efficiency targets. Cross-reference the 220 µH value against circuit simulation results before finalizing procurement orders.
Fixed Inductors Selection Notes
Select this component when a 220 µH inductance value is required for low-current applications up to 700 mA. The shielded design is suitable for space-constrained boards where EMI reduction is critical. Consider the operating temperature range of -20°C to +85°C for environmental compatibility. Compare the 470 mOhm resistance against alternative parts to optimize power loss profiles.
Fixed Inductors Part Context
This part belongs to the CTSLF1045 series of shielded power inductors manufactured by Central Technologies. The series offers various inductance values ranging from microhenries to millihenries.
