The Bourns 1140-330K-RC is a wirewound drum core fixed inductor designed for high current applications. Key specifications include 33µH inductance (tolerance ±10% measured at 1kHz), 15.8A RMS current rating (based on 50°C temperature rise and 5% inductance drop), and a low DC resistance of 11mOhm maximum. The component is unshielded and uses an epoxy coated ferrite bobbin core with VW-1 rated shrink tubing covering the winding. It is self-leaded with fixed lead spacing of 1.83mm.
The operating temperature range spans -55°C to +105°C. The inductor features a dielectric withstanding voltage of 2500Vrms (terminal to cover) and 1000Vrms (terminal to core). Package size is a radial vertical cylinder format with 38.10mm diameter and 26.16mm height. The through-hole mounting style and center hole for mechanical mounting make it suitable for board-level power circuits.
This component from the Bourns 1140 series is RoHS compliant and REACH unaffected. It is ideal for use in power supplies, DC-DC converters, and other applications requiring high current handling with moderate inductance values.
