74456147 Description

Short technical summary and product information.

The Würth Elektronik 74456147 is a fixed inductor from the WE-PD4 series, designed for surface mount power applications. It features a drum core, wirewound construction with a ferrite core and is unshielded. Key electrical specifications include an inductance of 47µH (measured at 100kHz/100mV) with ±10% tolerance, a rated current of 1.8A (based on 40K temperature rise), and a saturation current of 2.14A typical. The DC resistance is 0.142Ω typical and 0.19Ω maximum. The self-resonant frequency is 10MHz typical, and the maximum operating voltage is 120V DC.

 

This inductor is suitable for use in power supply circuits, DC-DC converters, and filtering applications where moderate current handling and inductance are required. The unshielded design may require consideration of electromagnetic interference in sensitive circuits. The component is RoHS, REACH, and Halogen Free compliant, with an MSL of 1 (unlimited floor life).

 

The package is a nonstandard surface mount case with dimensions 12.70mm x 10.00mm x 5.30mm (length x width x height). The operating temperature range is -40°C to 125°C. Storage conditions are below 40°C and 75% RH.
