1840-18K Description

Short technical summary and product information.

The 1840-18K is a fixed inductor manufactured by API Delevan, part of the 1840/R series. It offers an inductance of 3.3 µH with a tolerance of ±10%. The component is rated for a maximum DC current of 1.02 A and features a maximum DC resistance of 120 mOhm. With a minimum Q factor of 35 at 7.9 MHz and a self-resonant frequency of 70 MHz, this inductor is suitable for RF applications.

 

The inductor is constructed with an iron core and molded body, unshielded. It features axial terminations for through-hole mounting. The package dimensions are 0.187 inch diameter by 0.437 inch length (4.75 mm x 11.10 mm). It operates over a temperature range of -55°C to 105°C.

 

This component is designed for RF circuit applications requiring stable inductance and low DC resistance. Its unshielded design may require careful placement to avoid electromagnetic interference with nearby components. The molded construction provides mechanical robustness and consistent performance.
