UU11
INF
The UU11 Common Mode Line Choke is a professional-grade electromagnetic component built for stable common-mode noise filtering in industrial and commercial electronic systems. Adopting high-permeability ferrite UU core and F-class enamelled copper wire, this choke delivers consistent 70dB noise suppression and ultra-low stray inductance (~1%), making it a preferred solution for engineers and B-end buyers. Designed to meet strict EMC requirements, the UU11 Common Mode Line Choke integrates compact size, strong durability, and high electrical performance to support stable operation of power supplies, lighting, and communication equipment.
The UU11 Common Mode Line Choke provides exceptional attenuation of common-mode interference, effectively reducing EMI in power and signal circuits. Its minimal stray inductance ensures symmetric noise filtering without adding extra differential-mode interference, critical for high-precision industrial devices.
Built with a robust ferrite UU core, this choke features high saturation DC current and stable performance under heavy loads. It supports a wide operating temperature range of -40℃ to +125℃, adapting to harsh industrial environments and ensuring long service life.
This choke is fully RoHS compliant and UL 94 V-0 flame retardant, with halogen-free, lead-free materials that meet global environmental standards. It offers >1500V dielectric strength and pin strength ≥1.0kg, guaranteeing safe and stable installation on PCBs.
