The Wurth Electronics Inc 749013010 is a common mode choke designed to suppress unwanted noise and interference in electronic circuits. It is used to filter out common-mode noise, which is a type of electromagnetic interference (EMI) that affects both signal lines equally. This choke is particularly effective in reducing noise generated by switching power supplies, motor drives, and other sources of electrical noise.

Applications

• Switching power supplies
• Motor drives
• LED lighting
• Data communication lines (e.g., USB, Ethernet)
• Audio equipment

Features

• High common-mode impedance
• Low differential-mode impedance
• Compact size
• High current capability
• Excellent EMI suppression

Benefits

• Reduced EMI emissions
• Improved signal integrity
• Enhanced system reliability
• Compliance with EMC regulations

Additional Details

The 749013010 common mode choke is constructed with high-permeability ferrite core material, which provides excellent common-mode impedance over a wide frequency range. Its low differential-mode impedance ensures that the desired signals are not attenuated. The choke is designed to withstand high currents and offers a compact footprint for space-constrained applications. Detailed specifications, including impedance characteristics, current ratings, and operating temperature ranges, are available in the product datasheet.
