The OptoCooler HV37 module handles photonics cooling applications with larger heat pumping requirements. At +85°C, the component can pump 4.5W or 107 W/cm2 of heat in a 6 mm2 footprint measuring 0.6-mm high. At +85°C, it creates a temperature differential up to +60°C between its hot and cold sides, and operates at a maximum voltage of 7.7V. At +25°C, the device enables a temperature differential up to +50°C with a maximum voltage of 5.9V. Pricing is available upon request. NEXTREME THERMAL SOLUTIONS INC., Durham, NC. (919) 597-7300.
