The Bourns 78F390J-RC is a fixed inductor from the 78F series, offering an inductance of 39 µH with a tolerance of ±5%. It is rated for a maximum current of 240 mA and has a maximum DC resistance (DCR) of 1.7 Ohms. The component is designed with a ferrite core and is unshielded, making it suitable for general-purpose RF choke applications.
This inductor provides a minimum Q factor of 50 at 2.5 MHz and a minimum self-resonant frequency (SRF) of 9.5 MHz. It is housed in an axial package for through-hole mounting, with dimensions of 0.110" diameter by 0.280" length (2.79 mm x 7.11 mm). The operating temperature range is -55°C to 105°C, with a typical temperature rise of 35°C at rated current.
The 78F390J-RC is RoHS3 compliant and has an MSL rating of 1 (Unlimited). It is commonly used in DC/DC converters, power supplies, and general-purpose RF choke circuits.
