105-272H

Overview

The Delevan 105-272H is a fixed surface-mount 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 a rated current of 220 mA. The component utilizes an iron core within an epoxy encapsulated construction, housed in a non-standard 2-lead SMT package measuring 1.91 mm in height. It operates reliably across a temperature range of -55 °C to +125 °C.

Feature Summary

• Epoxy encapsulated construction for environmental protection
• Iron core design optimized for RF applications
• Non-standard two-lead surface mount configuration

Applications

• RF circuit filtering
• General purpose inductive components
• Signal processing networks

Procurement Notes

Verify the specific lead configuration and physical dimensions against the target PCB footprint prior to integration. Confirm that the 220 mA current rating meets the operational requirements of the intended circuit path. Ensure compatibility with the specified operating temperature range during final assembly validation.

Selection Notes

Select this component when a compact, shielded-free inductor is required for RF signal paths. The 2.7 µH value suits intermediate frequency applications. Consider the 2 Ω DC resistance impact on voltage drop. The epoxy coating provides mechanical stability for automated placement processes.

Part Context

This part belongs to the Delevan 105 series of fixed inductors. It shares the 2.7 µH nominal value with variants like the 105-272F but differs in compliance status and specific packaging details. The series focuses on general-purpose and RF uses with robust epoxy encapsulation.
