7440420027 Description

Short technical summary and product information.

The Würth Elektronik 7440420027 is a surface-mount shielded power inductor from the WE-TPC series. It offers a nominal inductance of 2.7 µH with a ±30% tolerance, measured at 100 kHz / 100 mV. The component is designed for power applications requiring a compact, shielded solution.

 

Key electrical characteristics include a rated current of 2.03 A (based on a 30 K temperature rise) and a typical saturation current of 2.2 A. The DC resistance is typically 47 mΩ, with a maximum of 60 mΩ. The self-resonant frequency is typically 90 MHz, making it suitable for DC-DC converter and power line filtering applications.

 

The inductor is housed in a 4818 (1919 metric) package measuring 4.80 mm x 4.80 mm with a height of 1.80 mm. It is designed for surface mount assembly and operates over a temperature range of -40°C to +125°C. The component is RoHS3 compliant, REACH conform, and halogen-free.
