FEATURES AND SPECIFICATIONS Molex expands its offering of Voltage Regulator Module (VRM) connectors with the addition of a 24-signal, 38-power circuit configuration The necessity for a highly efficient DC-to-DC power conversion to be located close to the processor is vital, especially in today’s high performance microprocessors. Molex provides such a solution in the iCool™ Low Profile VRM connectors. Incorporating a low loop inductance design, the iCool is created exclusively for high output currents at high slew rates for applications like servers, PCs and workstations. Designed for both the VRM 10.0 and 11.0 applications, these VRM connectors handle up to 150 amps of current (based on 400 FLM) in the 4.00” connectors under ambient temperatures of up to 60°C. Configurations of 200A or more. This new revision includes the series 78086. This new surface-mount version has a lower profile and narrower body compared to the rest of VRM connectors. This provides greater options for customers who have real estate constraints in their design. Features • High-temperature thermoplastic housing • Open housing design Benefits • Withstands lead-free process
