105R-272K

Overview

The Delevan 105R-272K is a surface-mount power inductor with an inductance of 2.7 µH and a tolerance of 10%. It features a maximum DC resistance of 2 Ohms and supports a maximum DC current of 220 mA. The component utilizes an iron core and epoxy encapsulation, measuring 2.54 mm in length, 1.27 mm in width, and 1.91 mm in height. It operates within a temperature range of -55 °C to +125 °C.

Feature Summary

Epoxy encapsulated construction for environmental protection
Iron core material for stable magnetic performance
Surface mount design for automated assembly

Applications

RF filtering circuits
General purpose inductive applications
Power supply chokes

Procurement Notes

Verify the specific suffix K indicates the standard tolerance variant. Confirm RoHS compliance status as historical data may vary. Check lead availability due to potential end-of-life status. Ensure package dimensions match PCB footprint requirements.

Selection Notes

Select this component when a 2.7 µH inductance with low current handling is required. Consider the 2 Ohm DC resistance impact on voltage drop. Evaluate the 220 mA saturation limit against peak load currents. Compare physical size constraints with alternative SMD packages.

Part Context

This part belongs to the Delevan fixed inductor family designed for surface mount technology. It serves as a passive component for energy storage and filtering in electronic circuits. The series offers various inductance values with consistent physical footprints for design flexibility.

Replacement Considerations

Direct substitutes include the 105R-272HS and 105-272K from API Delevan. Verify equivalent electrical parameters such as inductance, current rating, and resistance before substitution.
