Product Description

Wurth Elektronik 744821120 leaded inductor is a precision-engineered 20 mH manganese zinc core component optimized for electrical noise suppression in industrial and manufacturing applications. This radial mount inductor is capable of withstanding a maximum DC current of 500 mA and features a DC resistance of 1 Ω, making it suitable for power line input and output filtering in demanding environments.

The inductor exhibits a wide operating temperature range from -40°C to 125°C, conforming to IEC 60938-2 standards and UL 94 V-0 flame retardant specifications. Its compact design, with a length of 15 mm, diameter of 7.5 mm, and height of 17.5 mm, allows easy integration into a variety of circuit boards, supported by a 10 mm lead pitch and 0.7 mm lead diameter for seamless soldering.

Employing an anti-capacitance coiling technology, the WE-CMB series common mode choke provides high suppression of asymmetrical interferences even at low frequencies. This capability is critical in minimizing radio frequency interference in power electronics and motor control applications.

Applications include use in automotive electronic circuits, power electronics devices lacking grounding, and industrial motor filtering systems. The product's flammability rating and broad 125°C temperature tolerance ensure safe and reliable performance in harsh environments such as manufacturing plants and HVAC systems.

Compact radial design with manganese zinc core for efficient noise suppression. Maximum DC current rating of 500 mA and voltage rating of 1500V. Broad temperature range from -40°C to 125°C suitable for industrial applications.

Compliant with UL 94 V-0 flammability and IEC standards. Suitable for motor filtering and power line noise reduction in manufacturing and commercial installations.
