Description

Product Description
The SP1848-27145 is a specialized thermoelectric module engineered for high-performance thermal management and energy harvesting. While standard TEC modules are limited by lower temperature thresholds, the SP1848 series is designed to operate reliably at temperatures up to 120°C. This makes it an exceptional choice for demanding CPU cooling, industrial refrigeration, and high-heat DIY projects.
In addition to its cooling capabilities (Peltier Effect), this module is highly optimized for Thermoelectric Power Generation (Seebeck Effect). By applying a temperature difference across its ceramic plates, it can convert waste heat directly into usable DC electricity. Its internal structure is reinforced with high-purity semiconductor material to ensure consistent performance under thermal cycling, making it a versatile component for green energy research and precision thermal engineering.
Key Features
  • Dual-Function Technology: Functions as a high-precision cooler when powered, or as a solid-state power generator when exposed to a temperature gradient.
  • High-Temperature Tolerance: Specially formulated to withstand operating environments up to 120°C without degradation.
  • Superior Thermal Insulation: Optimized internal couples provide an excellent thermal barrier, preventing heat “back-leak” during cooling operations.
  • Solid-State Reliability: No moving parts or mechanical wear, ensuring silent operation and a long, maintenance-free lifespan.
  • Precision Manufacturing: Features flat, parallel ceramic plates for maximum surface contact and efficient heat transfer.
  • Eco-Friendly: Fully RoHS compliant; operates without refrigerants or ozone-depleting chemicals.
