TECs Pump Over 600 mW
Micropelt’s MPC-D40x Series of thermoelectric coolers (TECs) can pump over 600 mW with a drive current of 200 mA as required for thermal management of low power edge emitting lasers or VCSELs. The company’s micro-structuring technology enables them to produce TECs with an electrical resistance of more than 30 Ohms on a single square millimeter footprint. The TEC, in combination with its controller system, can therefore be driven at an efficiency of 90 percent and better, the company asserts.
