4379-473KS Description

Short technical summary and product information.

The 4379-473KS is a fixed inductor manufactured by API Delevan Inc. It offers an inductance of 47 µH with a tolerance of ±10%. The component is rated for a maximum DC current of 125 mA and features a maximum DC resistance of 3.2 Ohms. The inductor is shielded and uses a ferrite core material, which helps reduce electromagnetic interference. It is designed for surface mount assembly and comes in a nonstandard package with dimensions of 3.93 mm length, 3.17 mm width, and 3.56 mm height. The operating temperature range is -55°C to 125°C, making it suitable for a wide range of environments. The self-resonant frequency is 16 MHz, and the Q factor is 120 at 2.5 MHz. This component is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited). It is commonly used in power supply filtering, DC-DC converters, and other applications requiring compact, shielded inductors.
