Wurth Elektronik 7448040515 is a 15 mH Nano Crystal Common Mode Choke designed for effective suppression of common mode noise in power electronics and motor applications. It supports a maximum DC current of 5 A and features a low DC resistance of 38 mΩ, which helps minimize power loss while maintaining signal integrity. The choke has a maximum self resonant frequency of 300 MHz, making it suitable for broadband noise suppression tasks.
The device employs high permeability nano crystalline core material that ensures stable inductance values even at elevated temperatures up to 125°C. It is built with a through hole mount style, featuring durable solder termination for reliable PCB connection. The leads are 1 mm in diameter and spaced with a 10 mm pitch, tailored for standard industrial assembly processes.
With compact physical dimensions of 28 mm length, 32 mm height, and 19 mm depth, this choke fits efficiently into limited-space electronic designs. It complies with important international standards including VDE, RoHS, ENEC 10, and REACH, demonstrating its safety and environmental credentials. Its robust plastic case and winding spacer provide enhanced isolation and mechanical durability.
Typical applications include power line input and output filtering, radio interference suppression in motors, and noise reduction in various electronic circuits. Its small size and broad frequency range from 1 kHz to 300 MHz allow versatile deployment in industrial, automotive, and consumer electronics environments.
High permeability nano crystalline core for stability and performance. Through hole mounting and solder termination for secure PCB installation. Compliant with major safety and environmental standards. Designed for high current handling and low resistance operation.
Compact size for space constrained applications. Explore the Wurth Elektronik range at EnvMart for advanced electronic components and reliability in your projects.
