The 78F470J-RC is a conformal coated RF choke inductor designed for filtering and energy storage in DC/DC converters, power supplies, and general-purpose applications. It features an inductance value of 47 µH (±5%) with a quality factor (Q) of 60 at 2.5 MHz test frequency, a self-resonant frequency (SRF) of 8.50 MHz, and a DC resistance (DCR) of 2.00 O. The device is rated for a maximum DC current (IDC) of 205 mA and operates reliably over a temperature range of -55°C to +105°C, with a temperature rise of 35°C at rated current. The inductor is constructed with a ferrite DR core, enamelled copper wire, and Cu/Ni/Sn terminals, all protected by an epoxy resin conformal coating for enhanced reliability and environmental protection. This component is ideal for applications requiring compact, high-performance inductance with excellent frequency response and thermal stability.
