- High current handling capability suitable for power circuits
Applications
- Power supply filtering
- Signal processing circuits
- General-purpose RF applications
Procurement Notes
Verify the specific suffix 'SMLF' against official Gowanda documentation to confirm lead-free compliance and exact physical dimensions. Ensure the selected variant matches the required 1.6 A current rating and 155 mΩ DCR specifications for the target application environment.
Selection Notes
Select this component when a shielded surface-mount inductor is required for high-current applications. The 100 µH value and 1.6 A rating make it suitable for power management tasks where space efficiency and EMI reduction are critical design constraints.
Part Context
This part belongs to the KM series of shielded toroidal inductors from Gowanda Electronics. The series offers various inductance values and current ratings, providing engineers with standardized options for compact power electronics designs requiring reliable magnetic performance.
Replacement Considerations
Equivalent parts include the 040KM1003SMLF and 050KM1003SMLF. Verify that alternative models meet the same 100 µH inductance and sufficient current handling requirements before substitution.
