105-271F

Overview

The Delevan 105-271F is a fixed RF inductor with a nominal inductance of 2.7 µH and a tolerance of 1%. It features a maximum DC resistance of 2 Ω and utilizes an epoxy encapsulated construction with an iron core material. Designed for surface mount technology (SMT), the component adheres to the 1010 package dimensions, measuring approximately 2.54 mm in length, 2.54 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 inductance characteristics
• Surface mount design compatible with automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead availability through authorized distributors. Ensure the specific suffix matches required tolerance and packaging specifications. Cross-reference datasheet revisions for updated electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a 2.7 µH inductance value is required with tight 1% tolerance. The 2 Ω DC resistance limits current handling capabilities; verify circuit current requirements against the component's thermal performance. The 1010 footprint must be accommodated by the PCB layout constraints.

Part Context

This part belongs to the Delevan 105 series of micro chip inductors. It shares the same form factor and general application scope as variants like the 105-271K, differing primarily in tolerance specifications and manufacturing batch characteristics. The series is designed for compact RF applications requiring reliable performance.

Replacement Considerations

The 105-271K serves as a functional substitute with identical inductance but a wider 10% tolerance. Verify that the relaxed tolerance meets the circuit requirements. Other series components may differ significantly in physical dimensions or electrical characteristics.
