The Bourns 1120 series power chokes are engineered for applications requiring high current capacity and low DC resistance. These chokes feature an epoxy-coated ferrite bobbin core, providing excellent insulation and protection. They are self-leaded with fixed lead spacing and a center hole for mechanical mounting, enhancing design flexibility. With a dielectric withstanding voltage of 2500 Vrms and an operating temperature range of -55°C to +105°C, these chokes are suitable for demanding industrial and consumer electronics applications. The '-RC' suffix indicates RoHS compliance, ensuring environmentally responsible design.
