2890-18K Description

Short technical summary and product information.

The 2890-18K from API Delevan is an 8.2µH fixed inductor in a molded, unshielded axial-lead package. It offers a DC current rating of 555mA with a maximum DC resistance of 1.4Ω, and an inductance tolerance of ±10%. The component exhibits a Q factor of 60 at 7.9MHz and a self-resonant frequency of 68MHz, indicating useful high-frequency performance.

 

Constructed with a phenolic core and molded body, this through-hole inductor measures 0.280" diameter by 0.900" length (7.11mm x 22.86mm). It is designed for reliable operation across a wide temperature range of -55°C to 125°C. The axial lead configuration supports straightforward through-hole PCB mounting, and the unshielded design offers a cost-effective solution for designs where magnetic shielding is not required.
