Wurth WE-CMB XS, M and XL Series Common Mode Chokes
From Wurth Elektronik, the WE-CMB series of common modes chokes are a compact solution delivering high suppression of asymmetrical interferences, even at low frequency ranges. WE-CMB series common mode chokes offer the highest possible current for their ultra compact size. WE-CMB common mode chokes feature broadband screening due to the anti-capacitance coiling technique that has been incorporated into the design.
Features and Benefits:
Compact design
Climatic category: 40/125/21
IEC 60938-2
Flammability: UL 49 V-0
Wide operating temperature range of -40°C to +125°C
Product Applications:
WE-CMB common mode chokes are ideal for the suppression of common mode noise and the suppression of radio interferences in motors. Suitable applications include power line in and output filters, power electronics and the filtering of devices lacking a ground connection.
