The 78F681J-RC is a conformal coated RF choke inductor designed for filtering and energy storage in DC/DC converters, power supplies, and general electronic applications. It features an inductance value of 680 µH with ±5% tolerance, a quality factor (Q) of 60 at 0.79 MHz test frequency, and a self-resonant frequency (SRF) of 2.00 MHz. The component has a DC resistance of 25.3 O and supports a maximum DC current (IDC) of 65 mA, with a dielectric strength rating of 500 VRMS. Operating across a temperature range of -55°C to +105°C (including a 35°C temperature rise 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 in harsh environments. This RoHS-compliant component is ideal for applications requiring stable inductance and low electromagnetic interference in compact form factors.
