CR2050HT 3V 350mAh High Temperature Lithium Coin Cell Battery (-40°C to +125°C)

The CR2050HT is a high-temperature specialty industrial cell. By positioning its specialized HT (High Temperature) suffix, 350mAh capacity, and extreme -40°C to 125°C thermal threshold, this copy creates a robust data hub that perfectly answers specific technical queries from automotive and smart home engineers.

CR2050HT 3V 350mAh: The Thermal Warrior for Automotive TPMS & Smart Switch Systems

Engineered to Thrive Under Fire: Uncompromising 125°C Thermal Endurance

In high-velocity automotive systems and dense electrical enclosures, heat is the ultimate battery killer. Standard coin cells degrade, swell, or fail entirely when ambient temperatures climb. The CR2050HT shatters these operational limits. Combining a robust 350mAh capacity with a specialized High-Temperature “HT-Series” Electrochemistry, this 3V primary lithium manganese dioxide (LiMnO2) cell provides unwavering reliability under intense thermal and kinetic stress.

From the blistering interior of a high-speed tire to the confined heat of a smart wall switch, the CR2050HT delivers non-stop power across an extraordinary operational window of -40°C to +125°C

The “HT” Engineering Edge: Built for Severe Environments

The “HT” designation signifies a radical upgrade in internal cell architecture, explicitly engineered to counter the chemical acceleration caused by intense heat:

• Thermal-Stable Electrolyte: Formulated with a high-boiling-point organic electrolyte that prevents internal pressure build-up and gas generation up to 125°C.
• The 350mAh Power Reservoir: Optimized active material packing within the 5.0mm height provides a highly stable energy reserve, outlasting standard coin cells by keeping internal resistance flat over years of thermal cycling.
• Anti-Degradation Separator: Utilizes an advanced, heat-resistant composite separator that prevents internal micro-short circuits even under continuous high-temperature exposure.

Strategic Application Framework: TPMS & Smart Ecosystems

The CR2050HT is recognized as the definitive component for two major industries:

1. Automotive TPMS (Tire Pressure Monitoring Systems)

Tire sensors experience extreme centrifugal forces and severe heat generation during high-speed highway driving or braking. The CR2050HT is custom-engineered to withstand these relentless forces, ensuring continuous RF data transmission of pressure and temperature metrics directly to the vehicle’s ECU.

2. Next-Gen Smart Switches & Home Automation

Modern smart switches, in-wall dimmers, and IoT relays are packed into tightly confined, unventilated junction boxes. These environments suffer from localized heat generation caused by household AC currents. The CR2050HT acts as an unyielding backup or primary power source, ensuring the smart grid stays online without the risk of thermal swelling.

B2B Engineering Insight: Eliminating Product Recalls

“In the automotive and smart home sectors, component failure is a reputation killer.”

Replacing a failed battery inside a sealed TPMS module or an in-wall smart switch costs infinitely more than the component itself. By specifying the CR2050HT 350mAh cell, you are investing in product longevity, shielding your brand from expensive warranty claims, and minimizing the Total Cost of Ownership for your enterprise clients.
