The WE-HCI SMT High Current Inductor from Würth Elektronik (part number 7443556450) is a shielded wirewound inductor designed for high-current power applications. Its construction minimizes electromagnetic interference and provides robust performance in demanding environments.
Key electrical specifications include an inductance of 4.5 µH measured at 100 kHz/10 mA with a tolerance of ±20%. The rated current is 20.5 A maximum (based on a 50 K temperature rise), with a performance rated current of 23.5 A at 40 K rise. The saturation current is 16 A typical at 10% inductance drop and 37 A typical at 30% drop. DC resistance is typically 3.4 mΩ at 20°C, and the self-resonant frequency is 35 MHz.
The inductor operates over a temperature range of -40 to +150°C, with an ambient temperature limit of -40 to +100°C when referring to rated current. It is AEC-Q200 qualified for automotive use and complies with RoHS, REACH, and Halogen Free standards. Moisture sensitivity level is MSL 1.
The component is housed in a nonstandard 1890 package with dimensions of 18.3 mm x 18.2 mm x 9.2 mm, surface mountable. It is suitable for use in DC-DC converters, power supplies, and automotive power management systems. The recommended land pattern is provided in the datasheet for optimal thermal performance.
