78F2R7K-RC Description

Short technical summary and product information.

The Bourns 78F2R7K-RC is a conformal coated RF choke from the 78F series. This fixed inductor features a drum core wirewound construction on a ferrite core, providing an inductance of 2.7 µH with ±10% tolerance.

 

Key electrical specifications include a minimum quality factor (Q) of 50 at 7.9 MHz, a minimum self-resonant frequency (SRF) of 95 MHz, and a DC resistance (DCR) of 280 mΩ maximum. The component is rated for a maximum DC current of 595 mA.

 

The inductor is housed in an axial leaded package measuring 2.79 mm in diameter and 7.11 mm in length. It is designed for through-hole mounting and is unshielded. The construction uses enamelled copper wire with Cu/Sn terminal material and an epoxy resin coating.

 

This component is compliant with RoHS3 directives and has an MSL rating of 1 (unlimited). It is suitable for use in DC/DC converters, power supplies, and general RF applications where a reliable, fixed inductance value is required.
