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 with fixed lead spacing, and a center hole for mechanical mounting. They are suitable for a wide range of industrial applications including power supplies, DC-DC converters, and LED lighting. The -RC suffix indicates RoHS compliance, ensuring environmentally friendly operation. The dielectric withstanding voltage is 2500 Vrms terminal to shrink tube cover and 1000 Vrms terminal to core. Operating temperature ranges from -55°C to +105°C.
