Product Description
Wurth Elektronik 744311220 is a high-performance shielded wirewound surface mount inductor featuring the WE-HCI 7040 series. This inductor is designed with a WE-Superflux core and flat wire winding construction to deliver excellent magnetic shielding and very low DC resistance of 11.4mΩ, optimizing efficiency in high current applications up to 9 amperes. It operates reliably within a temperature range of -40°C to 150°C, making it suitable for industrial and automotive environments.
Measuring 7mm in length, 6.9mm in depth, and 3.8mm in height, the compact 7040 package is designed for surface mount technology (SMT) applications. The inductor's maximum self-resonant frequency is 52MHz, ensuring stable operation in switching regulators, DC-DC converters, and other power electronics requiring high frequency response. It meets automotive standard AEC-Q200 and complies with international environmental standards including RoHS, REACH, IEC 61249-2-21, and JEDEC JS709B.
Ideal for use in industrial computers, laptops, graphic cards, motherboards, and polyphase switching regulators, this inductor delivers reliable performance with minimal electromagnetic interference due to its magnetic shielding. The tape & reel packaging facilitates efficient automated placement and assembly.
Magnetically shielded wire wound construction minimizes stray magnetic fields. Flat wire coil design lowers DC resistance and improves current capacity. High temperature tolerance ensures stable operation up to 150°C. Compact 7040 package size for SMT applications.
Compatible with automotive industry standards (AEC-Q200). Compliant with RoHS, REACH, IEC, and JEDEC environmental standards. Maximum DC current rating of 9A supports high power density applications. WE-Superflux core material enhances magnetic performance.
Included in tape & reel for automated manufacturing processes.
The Wurth Elektronik WE-HCI 7040 shielded wirewound inductor series is engineered for demanding power electronics requirements, supporting efficient power conversion and robust operation in automotive and industrial sectors.
