🔷Thermoelectric Generator Product Overview

The TEC1-03501 is a semiconductor cooling module designed for precision temperature control in elongated spaces with moderate power requirements. With dimensions of 10 × 20 mm and a long, asymmetrical package design, it is optimized for compact devices that require a layout extending in a single direction—such as laser tube housings, beauty devices, and bar-shaped sensors—enabling active temperature management within irregular, confined spaces.

This product features a K14 crystal configuration with a thickness of 3.8 mm (typical). It offers a maximum cooling temperature difference of 65°C (under conditions where the hot-end temperature Th = 40°C). The maximum voltage is approximately 4.2 V, the maximum current is 3–5 A (typical), the maximum cooling power is approximately 9–15 W (typical), and the internal resistance is approximately 0.9–1.3 Ω (typical).

The 10×20 mm elongated package allows it to be easily embedded into narrow, elongated spaces such as the sides of laser casings, the interiors of beauty device handles, and strip-shaped sensor modules—while ensuring an effective temperature difference of 65°C and medium-to-high cooling power, it provides a 20 mm coverage range in the longitudinal direction and is only 10 mm wide, offering an ideal contact area for elongated heat sources. This product utilizes a 96% alumina ceramic substrate and a 0.2 mm oxygen-free copper sintering process to achieve a balance of excellent thermal conductivity and electrical insulation. It comes standard with 26 AWG silicone leads (100 mm in length), which are flexible and facilitate wiring in narrow, elongated spaces. The 704 silicone rubber perimeter seal provides excellent moisture, dust, and shock resistance. Its all-solid-state construction ensures precise operation with zero noise and zero vibration.

This product is typically used in applications such as temperature control for semiconductor laser casings, cold/hot therapy probes for beauty devices, temperature maintenance for strip-shaped sensors, temperature control modules for PCR instruments, and micro-laser modules. It is an ideal choice for temperature control requirements in long, narrow, and compact spaces.

🔷Thermoelectric Cooler Product Features

1. Long, asymmetrical design, ideal for narrow, elongated spaces

The unique 10×20 mm elongated package is optimized for narrow, elongated devices such as laser tube housings, beauty device handpieces, and bar-shaped sensors, making efficient use of limited space.

2. Ample cooling capacity for medium-power applications

With a maximum current of 3–5 A and a maximum power of 9–15 W, this elongated package delivers ample cooling capacity, making it suitable for compact devices with medium thermal loads.

3. Low-Voltage Drive, Excellent System Compatibility

With a maximum voltage of approximately 4.2V, it is compatible with single-cell lithium batteries (3.7–4.2V) or 5V USB power sources (with simple current limiting), simplifying power system design.

4. Wide Temperature Differential Coverage, Ample Cooling Capacity

Maximum cooling temperature differential of 65°C, with the cold end reaching as low as approximately -25°C, meeting the requirements of most precision temperature control applications.

5. High-Quality Substrate, Lightweight Design

The substrate is manufactured using a sintering process combining 96% alumina ceramic (0.76 mm) and oxygen-free copper (0.2 mm), resulting in a lightweight, low-thermal-capacity design with rapid temperature response.

6. Sealed Protection, Strong Environmental Adaptability

Sealed with 704 silicone rubber around the perimeter, it offers excellent moisture, dust, and shock resistance, making it suitable for complex environments with high humidity and significant temperature fluctuations.

7. Bidirectional Temperature Control, Dual-Function Single Element

Simply reversing the input current polarity activates heating mode, making it suitable for precision temperature-control systems requiring bidirectional temperature regulation (such as the alternating hot-cold mode in beauty devices).

8. Zero Noise, Zero Vibration, Precision Operation

The all-solid-state design ensures completely silent and vibration-free operation, making it ideal for high-precision applications with strict noise and vibration requirements.
