78F2R7K Description

Short technical summary and product information.

The Bourns 78F2R7K is a fixed inductor from the 78F series, featuring a conformal coated construction for protection against harsh environments. It offers an inductance of 2.7 µH with a tolerance of ±10%. The inductor is designed for RF applications, providing a minimum Q factor of 50 at 7.9 MHz and a self-resonant frequency of 95 MHz minimum.

 

Electrical specifications include a maximum DC resistance of 300 mΩ and a rated current of 355 mA, based on a 35°C temperature rise. The component is unshielded with a ferrite drum core, making it suitable for high-frequency circuits where electromagnetic interference is managed.

 

Packaged in an axial through-hole format, the inductor measures 0.110 inches in diameter and 0.280 inches in length (2.79 mm x 7.11 mm). It can operate over a temperature range of -55°C to 105°C and has a dielectric strength of 500 Vrms. Typical applications include RF filtering, impedance matching, and resonant circuits. The part is listed as RoHS, REACH and MSL level 1 compliant, but these claims are unverified.
