Product Description
The AXC-051 is a 3-terminal power filter which provide high attenuation starting at extremely low
frequencies ([email protected]). The device is designed for negative supply of 18 to 75 Volts and up to
5Amp load. The output voltage tracks the DC input voltage with 0.75V drop. Full performance is
kept for input ripple of up to 1.4 Volts p-p. Exceptional effort has been made to maintain low output
impedance (less than 0.1 ohm at audio frequencies). The AXC filters are designed to meet the most
stringent noise requirements in electronic equipment, telecommunication systems, audio equipment,
etc.
Applications
• Ultra Low Noise Switch Mode Power Supply
• Communication Systems.
