Product Description

Wurth Elektronik 744821201 is a 1 mH ferrite common mode choke designed for efficient noise suppression in electronic circuits. Rated for a maximum DC current of 2 A and a maximum voltage of 250 V AC, this choke is ideal for filtering common mode noise and enhancing electromagnetic compatibility in various applications.

The common mode choke features a ferrite core and a radial lead termination style with a lead diameter of 0.7 mm, mount type through hole, and a lead pitch of 4.5 mm. Its compact size includes a diameter of 15.5 mm, height of 18 mm, length of 15 mm, and a depth of 7.5 mm, allowing high-density mounting on printed circuit boards.

Designed to withstand a broad temperature range from -40°C to 125°C, it ensures stable performance under harsh industrial and automotive environments. The inductance tolerance of ±30 % provides reliable filtering characteristics at a test frequency of 10 kHz.

Wurth Elektronik's WE-CMB series uses an innovative anti-capacitance coiling technique offering broadband screening which is particularly effective in suppressing asymmetrical interferences at low frequencies. This choke is widely used in power line input/output filters, power electronics, and devices lacking ground connection to improve signal integrity and reduce radio interference.

Compliant with EN 61760-1:2006, the choke meets quality and safety standards for electronic components. Manufactured in China, it adheres to international regulations and automotive standards, although this specific model is not certified for automotive applications.

The choke’s compact design helps save PCB space without compromising performance. Ferrite core and low DC resistance contribute to minimal energy loss and heat generation. Reliable operation in industrial, laboratory, HVAC, and electronic manufacturing environments.

This Wurth Elektronik choke is a dependable choice for engineers and technicians seeking to reduce common mode noise and enhance electromagnetic compatibility in their electronic systems.
