The Bourns 1120 series high-current chokes are engineered to provide exceptional performance in demanding power applications. These chokes boast a very high current capacity and low DCR, minimizing energy loss and maximizing efficiency. The epoxy-coated ferrite bobbin core enhances durability and provides excellent insulation. They are self-leaded with fixed lead spacing and a center hole for mechanical mounting, offering versatility in design. Dielectric withstanding voltage is 2500 Vrms terminal to shrink tube cover; 1000 Vrms terminal to core. Operating temperature ranges from -55 to +105 °C. RoHS compliant models are identified by the “-RC” suffix.
