105-182F

Overview

The Delevan 105-182F is a fixed surface-mount RF inductor with an inductance of 1.8 µH and a tolerance of 1%. It features a maximum DC resistance of 1.5 Ohms and a rated current of 250 mA. The component utilizes an iron core within an epoxy encapsulated construction, measuring 2.54 mm by 2.54 mm with a height of 1.91 mm. It operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Epoxy encapsulated construction for environmental protection
• Iron core design for stable RF performance
• Surface mount termination style for PCB integration

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF applications

Procurement Notes

Verify component status as the 105-182F is listed as obsolete and no longer manufactured by API Delevan. Confirm RoHS compliance status, as sources indicate non-compliance. Ensure replacement parts meet identical electrical specifications including 1.8 µH inductance and 250 mA current rating before procurement.

Selection Notes

Select this component for applications requiring precise 1% tolerance in RF signal paths. Consider the 1.5 Ohm DC resistance impact on power loss. Verify compatibility with standard SMD reflow processes given the epoxy construction. Evaluate thermal limits against the specified 125 °C maximum operating temperature.

Part Context

Part of the 105R/108R series from API Delevan, designed for high-frequency electronic circuits. This specific model represents a legacy component in the manufacturer's portfolio of unshielded chip inductors used in radio frequency systems.

Replacement Considerations

Identify equivalent unshielded SMD inductors with 1.8 µH nominal value and 1% tolerance. Ensure substitute components support at least 250 mA current handling and fit the 1010 package dimensions.
