74404042033 Description

Short technical summary and product information.

The Würth Elektronik 74404042033 is a 3.3 µH semi-shielded power inductor from the WE-LQS series. It features a ferrite drum core with wirewound construction and a semi-shielded design to reduce electromagnetic interference. The inductor offers a rated current of 2 A based on a 40 K temperature rise, with a saturation current of 2.9 A typical. Its DC resistance is 55 mΩ nominal at 20°C. The self-resonant frequency is 56 MHz, and the maximum operating DC voltage is 120 V.

 

This component is AEC-Q200 Grade 1 qualified, making it suitable for automotive applications across a wide operating temperature range of -40°C to +125°C. It is fully compliant with RoHS, REACH, and Halogen Free standards, and has a Moisture Sensitivity Level (MSL) of 1 for unlimited floor life.

 

The inductor is supplied in a nonstandard 4018 SMD package measuring 4.00 mm x 4.00 mm x 1.80 mm, suitable for high-density surface mount assembly. It is designed for use in DC-DC converters, power supplies, and filtering circuits where space and performance are critical.
