🔷Peltier Module Product Overview

The TEC1-06303 is a semiconductor cooling module designed for precision temperature control in applications requiring a medium cooling area and medium-to-high power. With dimensions of 15 × 30 mm and a rectangular symmetrical package design, it provides ample heat exchange area while maintaining excellent spatial adaptability. It is optimized for compact devices such as laser modules, medical and cosmetic equipment, and analytical instruments that require a medium cooling area and handle high thermal loads.

This product is available in three crystal configurations—K10, K14, and K18—with thicknesses of 3.0 mm, 3.4 mm, and 3.8 mm, respectively, corresponding to maximum cooling temperature differences of 60°C, 65°C, and 70°C (under conditions where the hot-end temperature Th = 40°C). It features a maximum voltage of 7.6 V, a maximum current of 3.0 A, a maximum cooling power of 23 W, and an internal resistance of 1.98 Ω.

The 15×30mm rectangular package allows it to be embedded inside devices such as laser modules, medical probes, and analytical instruments—while ensuring a maximum cooling temperature difference of 70°C and high-power cooling of 23W, the 15mm width provides an excellent heat exchange area, helping to evenly transfer cooling capacity to the load surface. This product is designed to operate at 7.6V and 3.0A, making it highly compatible with common power supply platforms using two lithium batteries in series (7.4V), eliminating the need for complex power conversion. The low internal resistance of 1.98 Ω keeps Joule heating loss (I²R ≈ 17.8 W) at a reasonable level at 3.0 A, allowing more electrical energy to be converted into effective cooling capacity rather than self-generated heat. The substrate is manufactured using a sintering process combining 96% alumina ceramic (0.76 mm) and 0.2 mm oxygen-free copper. The thin copper layer reduces thermal mass, resulting in a more responsive temperature profile, making it particularly suitable for applications requiring rapid temperature ramping and frequent temperature switching. The 704 silicone rubber perimeter seal ensures a fully solid-state, noise-free, and vibration-free operation, delivering stable and reliable performance.

This product is typically used in applications such as laser module temperature control, hot and cold probes for medical and aesthetic devices, temperature stabilization for analytical instruments, PCR temperature control modules, heat dissipation for telecommunications equipment, and industrial laser processing equipment. It is an ideal choice for precision temperature control requirements in medium-sized spaces with medium-to-high power needs.

🔷TEC Cooler Product Features

1. Rectangular symmetrical design with ample heat exchange area

The 15×30 mm rectangular package features a 15 mm width that provides an excellent heat exchange area, facilitating uniform heat transfer to the load surface and making it suitable for medium-sized temperature-controlled devices.

2. High-power cooling with robust performance

With a maximum current of 3.0 A and a maximum power of 23 W, it achieves high power density cooling within a medium-sized package, making it suitable for compact devices with high thermal loads.

3. Deep cooling capability: Large temperature difference in a compact size

At 23 W, it achieves a maximum temperature difference of 70°C, with the cold end reaching as low as approximately -30°C, covering all application scenarios from conventional cooling to deep cooling.

4. Three Chip Options for Flexible Adaptation

Three chip configurations are available: K10 (60°C), K14 (65°C), and K18 (70°C). Users can flexibly select the appropriate model based on their target cooling depth.

5. Three Thickness Options to Suit Different Spaces

Thicknesses are 3.0 mm, 3.4 mm, and 3.8 mm. The K18 model, with a thickness of 3.8 mm, helps achieve 70°C deep cooling.

6. Low Internal Resistance Design for Efficient Energy Conversion

With an internal resistance of just 1.98 Ω, Joule heat loss is effectively controlled at a current of 3.0 A, ensuring that more electrical energy is converted into effective cooling capacity rather than self-generated heat.

7. Excellent Power Supply Compatibility

With a maximum voltage of 7.6 V, it is highly compatible with power supply platforms using two lithium-ion batteries connected in series (7.4 V). No complex power conversion is required, allowing for direct integration into common portable device power architectures.

8. Lightweight Substrate Design

The substrate is manufactured using a sintering process combining 96% aluminum oxide ceramic (0.76 mm) and oxygen-free copper (0.2 mm). The thin copper layer results in a lighter overall weight, lower thermal mass, and faster temperature response.

9. Thick Leads for Safe 3.0A Current Carrying

Comes standard with 24 AWG silicone-coated wire (100 mm in length), with a current-carrying capacity fully matched to 3.0 A, ensuring safe and reliable high-current transmission.

10. 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.

11. Bidirectional Temperature Control, Dual-Function Single Core

Simply reversing the input current polarity activates heating mode, making it suitable for precision temperature control systems requiring bidirectional temperature regulation.

12. 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.
