Yamaha offers a wide range of high performance thermoelectric coolers from 1mm×1mm micro-coolers to large scale 20mm×20mm coolers, all tailored to fit the wide variety of customer requirements. Our thermoelectric coolers are ideal for precision temperature control applications, such as the examples given below.

• Temperature control of optical crystals,lasers for optical communications , and high-power industrial lasers
• Temperature controls for sensors in CDs and light receiving elements
• Temperature control of biochips, hybridization equipment, and PCR equipment in the biological industry
• Temperature control of silicon wafers and chemicals in the semi-conductor industry

Yamaha has successfully improved the microstructure of its thermoelectric material to provide both lower electrical resistance and thermal conductivity. This has resulted in a further reduction in power consumption.

• Yamaha high-efficiency thermoelectric material
• Conventional thermoelectric material

Yamaha’s high-precision assembly technology enables high-density element packaging. This has allowed us to use a larger volume of heat absorbing material (a 20% increase on our previous products) on thermoelectric coolers of the same size.

• Yamaha high-density mounting for thermoelectric cooler elements
• Conventional thermoelectric cooler mounting

High strength thermoelectric material and high-density mounting afford higher strength characteristics than were previously possible (a 20% improvement over our previous products). In addition to resistance to thermal stress, our products are also extremely shock-resistant.

Yamaha’s thermoelectric coolers for optical communications are subjected to reliability testing based on the Telcordia Standard. Moreover, we conduct a range of reliability tests where requested by customers.

Yamaha’s realization of 1mm X 1mm ultra-small thermoelectric modules has allowed us to place thermoelectric coolers inside TO-CANs, making direct cooling and temperature control of lasers and sensors possible.

• Yamaha Ultra-small Thermoelectric Cooler
• Conventional thermoelectric cooler

These devices comply with the RoHS directives. Yamaha uses lead-free solder in the assembly of thermoelectric coolers
