RF Choke Bobbin Core 4.7uH 10% 7.96MHz 70Q-Factor Ferrite 620mA 400mOhm DCR AXL T/R ...
DESCRIPTION
The 77F4R7K-TR-RC is a conformal coated RF choke inductor from the Bourns 77F Series, designed for DC/DC converters, power supplies, and general RF filtering applications. It features an inductance of 4.7 µH with ±10% tolerance, a quality factor (Q) of 70 at 80 MHz test frequency, and a maximum DC resistance of 0.40 O. The device supports a DC current rating of 620 mA and has a self-resonant frequency (SRF) of 80 MHz, with a dielectric strength of 500 Vrms. Operating across a temperature range of -55°C to +105°C, this RoHS-compliant component is constructed with a ferrite core, polyester copper wire, and sn-ag-cu alloy terminal coating, making it suitable for demanding power management and signal conditioning circuits requiring reliable inductance performance.
