Lambda / TDK / EMI LLS9060

The Lambda/TDK EMI LLS9060 is a line filter engineered to suppress electromagnetic interference across power distribution and signal lines. It attenuates both common mode and differential mode noise, enabling compliance with EMC standards in industrial, medical, and commercial applications. The filter combines common mode choke inductors with X-capacitors to create a low-pass topology that blocks high-frequency noise while preserving signal integrity at operating frequencies.
