105-271H

Overview

The Delevan 105-271H is a fixed surface-mount inductor with an inductance of 270 nH and a tolerance of ±3%. It features a maximum DC current rating of 650 mA and a maximum DC resistance of 230 mΩ. The component utilizes an epoxy encapsulated construction with an iron core, designed for RF applications. It operates within a temperature range of -55 °C to 125 °C and is housed in a 1010 package.

Feature Summary

• Epoxy encapsulated construction for environmental protection
• Iron core design suitable for general purpose RF applications
• Surface mount technology compatible for PCB integration

Applications

• RF circuits
• Impedance matching networks
• Filtering applications

Procurement Notes

Verify the specific manufacturing lot and RoHS compliance status directly with API Delevan or authorized distributors, as historical data indicates potential lead-free variations. Confirm availability through official channels due to discontinuation risks associated with older component series. Ensure the selected variant matches the required tolerance and current specifications for the target circuit design.

Selection Notes

Select this component for high-frequency designs requiring stable inductance with moderate current handling. The 270 nH value and low DC resistance support efficient signal processing in compact layouts. Evaluate thermal performance against the 125 °C maximum operating limit. Compare physical dimensions of the 1010 package against board space constraints before finalizing the schematic.

Part Context

This part belongs to the Micro i Chip Inductors series by API Delevan, focusing on small form factor solutions for electronic systems. The 105 series typically addresses requirements for miniaturization in consumer and industrial electronics. As a legacy product, it represents earlier generations of SMD inductor technology characterized by robust epoxy packaging and iron core materials.
