# OptoTEC™ MSX Series **Tark Thermal Solutions** OptoTEC™ MSX Series delivers industry-leading micro multistage thermoelectric cooling performance in a compact footprint—engineered for seamless integration into a wide range of optical packages. Built with advanced ceramics, proprietary solder bonding, and next-generation thermoelectric materials, the MSX Series boosts cooling capacity by up to 10% while maintaining micro-scale dimensions. The multistage MSX Series TECs offer micro footprints on the cold side down to 2.0 x 4.0 mm with thicknesses down to 3.3 mm for 2-stage, 3.8 mm for 3-stage. Heat-pumping capability up to 5 W, these solid-state, low-current coolers provide reliable, maintenance-free temperature stabilization from room temperature down to 180 K with zero outgassing. ![](/thermal-wizard/images/MSX-Family.png) ## Features - Miniature footprints - Precise temperature control - Reliable solid-state operation - Operates in high-temperature applications - No sound or vibration - RoHS-compliant ## Applications - [Infrared Range Sensors​](/applications/infrared-range-sensors) - [Charge-Coupled Devices (CCD)​](/thermal-technical-library/application-notes/multistage-micro-thermoelectric-coolers-optical-image-sensing-applications) - [X-Ray Detectors](/applications/cooling-cmos-sensors) ## Products in this series - [MSX2-041-F1N-0707-06-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014127) — MFG Part Number: 387014127; Maximum Cooling Power (Qc): 1.3 W - [MSX2-041-F1N-0707-08-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014128) — MFG Part Number: 387014128; Maximum Cooling Power (Qc): 13.5 W - [MSX2-041-F1N-0707-10-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014129) — MFG Part Number: 387014129; Maximum Cooling Power (Qc): 13.5 W - [MSX2-041-F1N-0707-15-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014131) — MFG Part Number: 387014131; Maximum Cooling Power (Qc): 13.5 W - [MSX2-041-F1N-0707-13-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014130) — MFG Part Number: 387014130; Maximum Cooling Power (Qc): 13.5 W - [MSX2-041-F1N-0707-12-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014132) — MFG Part Number: 387014132; Maximum Cooling Power (Qc): 13.5 W - [MSX2-041-F1N-0707-09-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014438) — MFG Part Number: 387014438; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-09-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387009176) — MFG Part Number: 387009176; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-06-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014545) — MFG Part Number: 387014545; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-082-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014546) — MFG Part Number: 387014546; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-085-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014547) — MFG Part Number: 387014547; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-10-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014548) — MFG Part Number: 387014548; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-12-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014549) — MFG Part Number: 387014549; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-13-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014550) — MFG Part Number: 387014550; Maximum Cooling Power (Qc): 13.5 W - [MSX3-070-F1N-0808-15-11-W2](/products/thermoelectric-cooler-modules/micro-MSX-series/387014551) — MFG Part Number: 387014551; Maximum Cooling Power (Qc): 13.5 W ## ![](/thermal-wizard/images/2stagemsx.png)2-Stage Thermoelectric Coolers ## ![](/thermal-wizard/images/3stagemsx.png)3-Stage Thermoelectric Coolers ## General Specifications **Series (Solder Construction)** | Model | Solder Type | Melt Temp | |---|---|---| | MSX | (SnSb) Tin Antimony | 232°C | | HSX | (AuSn) Gold Tin | 280°C | **Ceramic Materials** | Ceramic Materials | Thermal Conductivity | Option | |---|---|---| | (ALO) Alum Oxide | 24 W/mK | F1 | | (ALN) Alum Nitride | 170 W/mK | F1N | **Surface Finish Options** | Solder Type | Melt Temp | Option | |---|---|---| | Au plating (Hot/Cold Surface) | | GG | | Non-Metallized Hot and/or Cold face | | 11 | | Pre-tinning Hot and/or Cold face with 118˚C InSn Solder | 118˚C | 22 | | Pre-tinning Hot and/or Cold face with 138˚C BiSn Solder | 138˚C | 33 | **Lead Attachment** | Solder Type | Option | |---|---| | Uninsulated leads (2 inches) | W2 | | Au plated Posts | WO | ## Optical TEAs MSX multistage micro thermoelectric coolers are available as a standalone or integrated into an optical package called **Optical TEAs**. **Tark Thermal Solutions** has a proprietary bonding technique to adhere TECs to optical packages with minimal solder voiding.
