The Vicor MicroRAM URAM3M22 is an output ripple attenuator module that combines active and passive filtering to achieve significant noise attenuation. It offers 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 and provides precise point-of-load voltage regulation. The URAM3M22 supports redundant and parallel operation through its integrated ORing diode function.
Designed for compatibility with various switching converters, including Vicor's own VI-200/VI-J00 and Maxi, Mini, and Micro series, the URAM3M22 is suitable for applications requiring clean power delivery. It features a long pin style and a threaded baseplate for mounting.
Key specifications include an operating temperature range of -20°C to +100°C. While RoHS3 compliant, the verification status for RoHS, REACH, and MSL is currently low confidence due to the absence of specific documentation.
