The Bourns 1120 series power chokes are designed for applications requiring high current capacity and low DC resistance. These chokes feature an epoxy-coated ferrite bobbin core, self-leaded construction, and fixed lead spacing for easy mechanical mounting. They are suitable for use in power supplies, DC-DC converters, and other industrial applications where efficient power management is critical. The -RC suffix indicates RoHS compliance, ensuring environmentally responsible design. The dielectric withstanding voltage is 2500 Vrms terminal to shrink tube cover and 1000 Vrms terminal to core.
