Please download the latest datasheet of CR2477W-HE2 from the official website of Murata Manufacturing Co., Ltd. http://www.murata.com/en-GB/products/productdetail?partno=CR2477W-HE2 Product Search Data Sheet ## CR2477W-HE2 The Heat-resistant lithium coin batteries support wider operating temperature -40 to +125 °C and are ideal for devices used in severe temperature environments such as TPMS etc. ## Appearance & Shape ## Features **• Lightweight, High Voltage and High Energy Density** The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space saving and weight reduction. ## **• Excellent Discharge Characteristics** Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenancefree (battery replacement is seldom required). ## **• Outstanding Temperature Characteristics** Murata's original organic electrolyte provides superb characteristics over a wide range of temperature from low to high. ## Applications -40 to +85 degrees C (Extended temperature) -40 to +125 degrees C (Heat-resistant) ## **• Excellent Leakage Resistance** ●Automotive[・] TPMS(Tire Pressure Monitoring System)[・] Toll collection device ●IoT/Others[・] Factory Other Usage Automation Instruments[・] Smart meters[・] Tracking devices The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time. ## **• Excellent Long-Term Reliability** Carefully selected active materials are used for the active material as well as for the electrolyte. These materials are sealed by Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the nominal capacity. ## **• UL Approved Parts** Sony's Coin Manganese Dioxide Lithium Batteries are approved by UL. (UL1642 File No. MH12566) ## **• RoHS directive / European Directives** This product does not contain Mercury(Hg), Cadmium(Cd), nor Lead(Pb), and conforms to EC regulation values. 1 of 3 ## **Attention** - 1.This datasheet is downloaded from the website of Murata Manufacturing Co., Ltd.
