The 77F102J-TR-RC is a conformal coated RF choke from the Bourns 77F series, designed for general-purpose filtering applications. It provides a nominal inductance of 1000 µH with a ±5% tolerance, a minimum quality factor (Q) of 50, and a minimum self-resonant frequency (SRF) of 1.2 MHz. This component has a maximum DC resistance (DCR) of 20.0 Ω and can handle a maximum DC current of 100 mA. Built with a ferrite core and an epoxy resin coating, this RoHS compliant choke is well-suited for use in power supplies and DC/DC converters.
