105-272F

Overview

The Delevan 105-272F is a fixed surface-mount RF inductor with an inductance of 2.7 µH and a tolerance of 1%. It features a maximum DC resistance of 2 ohms and a self-resonant frequency of 68 MHz. The component utilizes an iron core and epoxy encapsulation within a non-standard 2-lead SMT package measuring 1.91 mm in height. It operates reliably between -55 °C and 125 °C.

Feature Summary

• Epoxy encapsulated construction for environmental protection
• Iron core design optimized for RF applications
• Surface mount termination for automated PCB assembly

Applications

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

Procurement Notes

Verify the specific lead configuration and physical footprint dimensions against your PCB layout, as the package is described as non-standard. Confirm that the 2-ohm DC resistance meets your circuit's power loss requirements. Ensure the operating temperature range aligns with your system's thermal environment. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a precise 2.7 µH value with tight 1% tolerance is required for high-frequency applications. The low DC resistance supports efficient signal transmission. Consider the self-resonant frequency to ensure performance stability at your target operating frequency. Verify that the unshielded nature does not cause interference in dense layouts.

Part Context

This part belongs to the API Delevan 105 series of fixed inductors. The series offers various inductance values with consistent physical characteristics. These components are designed for general-purpose use in electronic circuits requiring stable inductive properties.

Replacement Considerations

Cross-reference with other 2.7 µH SMD inductors from different manufacturers. Ensure equivalent inductance, tolerance, current handling, and self-resonant frequency. Verify mechanical compatibility including terminal type and body size.
