105R-271G

Overview

The Delevan 105R-271G is a fixed surface-mount inductor with a nominal inductance of 270 nH. It features an unshielded construction and supports a maximum current rating of 650 mA. The component exhibits a maximum DC resistance of 230 mOhm. Designed for general-purpose applications, it utilizes a non-standard package configuration with two leads.

Feature Summary

• Unshielded design suitable for specific electromagnetic interference requirements
• Fixed inductance value optimized for RF signal processing
• Surface-mount technology for automated assembly integration

Applications

• RF circuit filtering
• General-purpose inductive components
• Signal conditioning networks

Procurement Notes

Verify the exact physical dimensions against the official datasheet due to the non-standard package designation. Confirm that the 650 mA current rating meets the operational requirements of the target circuit. Ensure compatibility with standard reflow soldering profiles for surface-mount components.

Selection Notes

Select this component when a low-inductance value near 270 nH is required without magnetic shielding constraints. Consider the 230 mOhm DC resistance impact on power efficiency. Evaluate the non-standard footprint availability during PCB layout planning to ensure proper pad design.

Part Context

This part belongs to API Delevan's fixed inductor portfolio, specifically within the micro chip inductor series. It represents a passive electronic component used primarily in high-frequency analog and radio frequency circuits where precise inductance values are critical for impedance matching or filtering.

Replacement Considerations

Cross-reference with other 270 nH unshielded SMD inductors from different manufacturers if supply constraints exist. Verify that substitute parts match the 650 mA current handling capability and similar DC resistance characteristics to maintain circuit performance integrity.
