The 1120-470K-RC is a high-current choke inductor designed for demanding power supply and filtering applications. It features an inductance of 47 µH at 1 kHz with a DC resistance of 0.035 O (±20%), supporting a rated current of 5.5 A with a maximum 50°C temperature rise. The component utilizes an epoxy-coated ferrite bobbin core with VW-1 rated shrink tubing, self-leaded construction, and fixed lead spacing for reliable mechanical mounting. It offers dielectric withstanding voltage ratings of 2500 Vrms (terminal to shrink tube cover) and 1000 Vrms (terminal to core), with an operating temperature range of -55°C to +105°C. This choke is ideal for EMI suppression, power factor correction, and DC-DC converter applications where low DCR and high current capacity are essential.
