The 7440450039 is a surface-mount fixed inductor from Würth Elektronik's WE-LQ series. It offers an inductance of 3.9 µH (measured at 1 MHz, 100 mV) with a tolerance of ±20%. The component is designed for power applications, with a rated current of 1.32 A (maximum, based on a 40 K temperature rise) and a saturation current of 2.5 A typical.
The inductor features a maximum DC resistance of 0.14 Ω at 20°C and a typical self-resonant frequency of 54 MHz. The Q factor is 40 at 1 MHz. It is constructed with a ferrite core and unshielded drum core wirewound design, housed in a 1812 (4532 Metric) package with dimensions 4.5 mm x 3.2 mm x 2.6 mm (nominal).
The component operates over a temperature range of -40°C to 125°C, with an ambient temperature range for rated current of -40°C to 85°C. It is RoHS, REACH, and Halogen Free compliant, with an MSL rating of 1 (unlimited).
