The 1140-220K-RC is a high-current choke inductor from Bourns' 1140 Series, designed for demanding power supply and filtering applications. It features an inductance of 22 µH (±20% @ 1 kHz) with a maximum DC resistance of 0.009 O, enabling efficient energy storage and filtering with minimal power loss. The device is rated for 16.2 A RMS continuous current with a saturation current of 43.7 A, and operates reliably across a wide temperature range of -55°C to +105°C. The choke incorporates an epoxy-coated ferrite bobbin core with VW-1 rated shrink tubing, self-leaded tinned leads, and a center hole for mechanical mounting, providing robust construction and ease of integration. With dielectric withstanding voltages of 2500 Vrms (terminal to shrink tube cover) and 1000 Vrms (terminal to core), this component is well-suited for high-reliability power conversion, EMI filtering, and current smoothing in industrial and telecommunications equipment.
