106-473K

Overview

The Delevan 106-473K is a fixed surface-mount inductor from the 106 series. It features an inductance of 47 µH with a tolerance of ±10%. The component has a maximum DC resistance of 19 Ohms and a rated current of 70 mA. It utilizes an iron core and is unshielded. The package size is nonstandard, measuring approximately 3.9x2.8mm. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Fixed inductance value for stable circuit performance
• Iron core construction for specific magnetic properties
• Surface mount design for automated assembly

Applications

• RF circuits requiring fixed inductance
• General purpose filtering applications
• Signal processing stages

Procurement Notes

Verify the exact physical dimensions against your PCB footprint, as the 106 series uses a nonstandard package size distinct from common metric standards. Confirm that the 70 mA current rating meets your circuit's operational requirements. Ensure the unshielded nature does not cause interference issues in dense layouts. Check RoHS compliance status if required by your manufacturing specifications.

Selection Notes

Select this component when a 47 µH inductance is needed with a high DC resistance profile. The 106 series is suitable for applications where standard footprints are unavailable or specific nonstandard dimensions are required. Consider the low current rating of 70 mA for power handling limits. Compare against shielded alternatives if EMI mitigation is necessary.

Part Context

The 106 series by API Delevan consists of fixed chip inductors designed for general-purpose and RF applications. These components typically feature iron cores and are available in various inductance values. The series is characterized by its unique form factor, distinguishing it from standard SMD packages like 1206 or 1210.

Replacement Considerations

Direct substitutes include other Delevan 106 series parts with similar electrical characteristics. Cross-referencing with generic 47 µH unshielded SMD inductors may be possible if mechanical dimensions can be adapted. Verify pin compatibility and thermal performance before substitution.
