RTC is called “clock chip” and is used to record and track time. Its interrupt function can wake up devices in the network at regular intervals, allowing other modules of the device to sleep most of the time, thereby greatly reducing the overall power consumption of the device.
Since the device time cannot have any deviation, the application scenarios of RTC clock power supply are becoming more and more numerous, and it is widely used in security monitoring, industrial equipment, smart meters, cameras, 3C products and other fields.
RTC backup power supply better solution · SMD supercapacitor
RTC is in an uninterrupted working state. In order to ensure that RTC can still work normally under power outages or other abnormal conditions, a backup power supply (battery/capacitor) is required to provide stable power supply. Therefore, the performance of the backup power supply directly determines whether the RTC can operate stably and reliably. How to make the RTC module achieve low power consumption and long life, the backup power supply plays an important role in it.
The backup power supply of RTC clock chips on the market is mainly CR button batteries. However, CR button batteries are often not replaced in time after they are exhausted, which often affects the user experience of the entire machine. To solve this pain point, YMIN conducted in-depth research on the actual needs of RTC clock chip-related applications and provided a better backup power solution – SDV chip supercapacitor.
SDV chip supercapacitor · Application advantages
SDV Series：
High and low temperature resistance
SDV chip supercapacitors have excellent temperature adaptability, with a wide operating temperature range of -25℃~70℃. They are not afraid of harsh environmental conditions such as extreme cold or extreme heat, and always operate stably to ensure equipment reliability.
No replacement and maintenance required:
CR button batteries need to be replaced after they are exhausted. Not only do they not change after replacement, but they often cause the clock to lose memory, and the clock data becomes chaotic when the device is restarted. To address this problem, SDV chip supercapacitors have the characteristics of ultra-long cycle life (more than 100,000 to 500,000 times), which can be replaced and maintenance-free for life, effectively ensuring continuous and reliable data storage, and improving the customer’s overall machine experience.
Green and environmentally friendly:
SDV chip supercapacitors can replace CR button batteries and are directly integrated into the RTC clock solution. They are shipped with the whole machine without the need for additional batteries. This not only reduces the environmental burden brought by battery use, but also optimizes production and logistics processes, contributing to green and sustainable development.
Manufacturing automation:
Different from CR button batteries and conntional supercapacitors that require manual welding, SMD supercapacitors support fully automatic mounting and can directly enter the reflow process, greatly improving production efficiency while reducing labor costs and helping to upgrade manufacturing automation.
Summary
At present, only Korean and Japanese companies can produce imported 414 button capacitors. Due to import restrictions, the demand for localization is imminent.
YMIN SMD supercapacitors are a better choice for protecting RTCs, replacing international high-end peers and becoming the mainstream RTC-mounted capacitor.
