KEMET Launches FMU Series of High-Performance Supercapacitors for Automotive Electronics with Extended Lifespan and Reliability.

KEMET has announced the launch of a new high-performance supercapacitor series, the FMU series, for energy storage and other applications in automotive electronics. These miniature supercapacitors can operate at a temperature range of -40°C to 105°C, providing longer lifespan, higher power density, faster charging, and greater reliability. They are designed to meet automotive testing requirements, produced in ISO TS 16949-certified factories, and support PPAP/PSW and change control.

Supercapacitors are an excellent alternative to batteries in automotive electronics, as they can provide backup power support during power outages, such as those required for ADAS, autonomous vehicles, and central gateway ECU. These capacitors can also keep real-time clocks or volatile memories functioning when the main power source system is removed, such as during power failure or when the main power source system battery is replaced.

In addition, supercapacitors are ideal for providing power backup support for IoT devices, smart meters, medical equipment, and industrial computing applications. They store enough energy to provide backup support for several seconds to several hours, depending on the load type and current demand. Unlike batteries, supercapacitors store and release energy quickly through physical adsorption and ion desorption between the electrolyte and the electrode. They have a low internal resistance, allowing them to be fully charged within seconds, compared to batteries that can take several minutes to several hours to charge fully.

KEMET's FMU series uses proprietary water-based electrolyte solutions that provide high durability, preventing liquid leakage, vibration, and thermal shock, making them highly reliable in harsh environments. These electrolytes are highly conductive, have minimal environmental impact, are non-toxic, and less flammable. The advanced water-based technology has enabled the FMU series to become the first supercapacitors capable of withstanding high temperatures up to 105°C.

The global supercapacitor market reached $4.4 billion in sales revenue in 2022 and is projected to reach $15.2 billion by 2028, with a compound annual growth rate of 22.95%, according to Markets and Research reports. The increasing demand for energy-saving devices in electric vehicles, solar and wind energy systems, and industrial applications for monitoring and stabilization are driving the rapid growth of the global supercapacitor market.
