The 78F102J-TR-RC is a conformal coated RF choke inductor from Bourns' 78F Series, designed for RF filtering and power supply applications. It features an inductance value of 1000 µH (±5%), a quality factor (Q) of 60 at 0.79 MHz test frequency, and a self-resonant frequency (SRF) of 1.20 MHz. The component has a DC resistance (DCR) of 31.4 O and supports a rated DC current (IDC) of 60 mA, with a maximum temperature rise of 35°C at rated current. The inductor operates reliably across a temperature range of -55°C to +105°C and features an epoxy resin conformal coating for environmental protection. It is commonly used in DC/DC converters, power supplies, and general RF filtering applications where compact size and high inductance values are required.
