High Operating Temperature Integrated Fan Heat Sinks DESIGN FEATURES Industry-leading maximum operating temperature of 90C Compatible with chipset footprints ranging from 21x21 mm to 45x45 mm Total heights from 16.1 mm for low profile applications to 44.6 mm for lowest thermal resistance Common 5VDC 0.5 A (max) USB 2.0 fan electrical specifications Forged and extruded versions available Choice of elliptical, round pin, and plate fin styles DESCRIPTION The FHS-090 Series of integrated-fan heat sinks is uniquely designed to absorb and disperse heat away from high temperature devices while offering key features such as an operating temperature range of -10C to 90C, calculated MTTF 90C: 86,858 hours (GEM, 90% confidence) and various package sizes to best fit the application. Thermal resistance values range from 4.07C/W to as low as 1.24C/W. These new fansinks can maintain superior thermal dissipation for devices that emit high amount of heat. CTS fansinks are available in a wide range of footprints and fin heights which make them suitable for many elevated temperature applications such as component testing, burn-in, high density servers, high- speed computing and video, and use in areas where the system airflow is constrained.
