The Vicor MicroRAM URAM3M23 is an output ripple attenuator module that combines active and passive filtering techniques to achieve significant noise reduction. It provides greater than 40dB of noise attenuation across a frequency range of 60Hz to 1MHz.
This module operates over a wide input voltage range of 3 to 30V DC and is rated for 20A. Its closed-loop architecture enhances load-transient response through dual-mode control, ensuring precise point-of-load voltage regulation. The integrated ORing diode function supports redundant and parallel operation.
The URAM3M23 is compatible with most manufacturers' switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series DC-DC converters. It is suitable for applications requiring clean power delivery and improved signal integrity.
This specific model features a long pin style and a threaded baseplate for mounting.
