78F221J-RC
RF Choke Bobbin Core 220uH 5% 790KHz 60Q-Factor Ferrite 130mA 6.8Ohm DCR AXL Bag ...
DESCRIPTION
The 78F221J-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 220 µH with ±5% tolerance, a quality factor (Q) of 60 at 0.79 MHz test frequency, and a self-resonant frequency (SRF) of 4.00 MHz. The component has a DC resistance (DCR) of 6.80 O and supports a maximum DC current (IDC) of 130 mA, 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. It operates reliably across a temperature range of -55°C to +105°C and meets RoHS compliance requirements, making it suitable for demanding industrial and consumer electronics applications requiring high reliability and environmental protection.
