7440700047 Description

Short technical summary and product information.

The Würth Elektronik WE-TPC series 7440700047 is a shielded power inductor designed for surface mount applications. It features a ferrite core and provides 4.7 µH inductance with ±30% tolerance at 100 kHz and 10 mA. The component is rated for a typical current of 3 A (ΔT = 40 K) and has a saturation current of 2.2 A typical. DC resistance is 37 mΩ typical and 45 mΩ maximum at 20°C. The self-resonant frequency is 65 MHz typical. This inductor operates over a temperature range of -40°C to +125°C and is compliant with RoHS, REACH, and Halogen Free standards, with an MSL rating of 1. The package is a nonstandard SMD form factor with dimensions 8 mm x 8 mm x 2.4 mm (nominal). The shielded construction minimizes electromagnetic interference, making it suitable for power supply and DC-DC converter circuits in compact electronic devices.
