Industry-leading maximum operating temperature of 90°C
Compatible with chipset footprints ranging from 21x21 mm to 55x55
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
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 -10°C to 90°C,
calculated MTTF @ 90°C: 86,858 hours (GEM, 90% confidence) and various package sizes to best fit the
application. Thermal resistance values range from 3.45 °C/W to as low as 0.51 °C/W.
These new fansinks can maintain superior thermal dissipation for devices that emit high amount of heat.
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.
