🔷Thermoelectric Peltier Performance Curve
🔷Thermoelectric Module Product Overview
The TEC1-04901 is a 25×25mm ultra-low-power semiconductor cooling module (Peltier device) designed for extremely low current consumption (1.4A), specifically engineered for micro-power precision temperature control applications where power consumption and space are critical considerations. This product has a maximum voltage of 5.8V, a maximum temperature difference of up to 65°C, and a cooling capacity of approximately 8–10W. Its core value lies not in “powerful cooling,” but in providing fast, stable, and low-power localized temperature control—with minimal thermal inertia, it can reach the target temperature difference within a short time after power-up. As a solid-state device, the TEC1-04901 is noise-free, vibration-free, and maintenance-free, and can freely switch between cooling and heating modes simply by reversing the current direction.
🔷Peltier Device Product Features
⚙️ Key Performance Features
Ultra-low-power design: Designed for a low current of approximately 2A, it can be conveniently powered by USB (5V), making it ideal for portable or battery-powered devices.
Practical temperature control capabilities: The maximum temperature difference (ΔTmax) reaches 65–68°C. Although the cooling power is modest (Qcmax approximately 6.86W), it is sufficient to meet the needs of precise localized temperature control.
Compact 25×25mm Package: This is a key feature that distinguishes it from larger models in the same series. Its small size allows for easy integration into space-constrained designs such as smartphone cooling back covers and micro-sensors.
💡 Application and User Experience Features
Plug-and-play, precise temperature control: As a solid-state device, it operates silently, vibration-free, and maintenance-free, with fast response times, making it particularly suitable for scenarios requiring rapid and precise temperature control.
Flexible switching, dual-purpose operation: By reversing the current direction, you can freely switch between cooling and heating modes, increasing design flexibility.
Designed for “Microenvironment” Temperature Control: Its low power consumption and compact size make it ideal for providing stable “microenvironment” temperature management for precision components such as laser projectors, sensors, and IC chips.
Usage Tip: As with all TECs, this product must be equipped with an efficient heat sink or fan on the hot side (heating surface) during operation; otherwise, heat buildup will cause cooling efficiency to drop sharply and may even damage the module.
