The part number **1MD04-059-10** corresponds to a high-performance **Thermoelectric Cooler (TEC)**, also known as a Peltier Module, manufactured by **II-VI Incorporated** (now part of **Coherent Corp.**). These components are used for precise temperature control in optoelectronic devices. --- ### 1. Technical Specifications The "1MD04" series is part of a specialized line of miniature single-stage coolers. Below are the typical characteristics for this specific model: | Parameter | Value (Approximate) | | :--- | :--- | | **Type** | Single-Stage Thermoelectric Cooler | | **Max Temperature Differential ($\Delta T_{max}$)** | ~67°C to 72°C (in vacuum) | | **Max Current ($I_{max}$)** | ~1.0 A to 1.2 A | | **Max Voltage ($V_{max}$)** | ~7.2 V | | **Cooling Capacity ($Q_{max}$)** | ~4.5 W to 5.0 W | | **Number of Couples** | 59 | | **Metallization/Surface** | Gold-plated (often denoted by the -10 suffix) | --- ### 2. Key Features * **Miniature Footprint:** Designed for integration into small packages like TO-cans or Butterfly laser packages. * **High Reliability:** Built to meet Telcordia GR-468 standards for long-term stability in telecommunications. * **Gold Plating:** The "-10" suffix usually indicates specific finishing, such as **Gold (Au)** plating on the hot and cold ceramic faces, allowing for fluxless soldering or wire bonding. * **Precise Control:** Capable of maintaining sub-degree temperature stability when paired with a thermistor and a PID controller. --- ### 3. Common Applications These parts are rarely found in consumer electronics; they are primarily used in industrial and scientific equipment: 1. **Laser Diode Cooling:** Stabilizing the wavelength of telecommunication lasers. 2. **Infrared (IR) Sensors:** Reducing thermal noise in high-sensitivity detectors (e.g., gas sensing or thermal imaging). 3. **Laboratory Equipment:** Precise temperature regulation for microfluidics or DNA amplification. 4. **Optical Transceivers:** Used in high-speed data center networking modules (QSFP/OSFP). --- ### 4.
