Eaton Electronics, a leading supplier, offers a wide range of supercapacitors, from miniature components to larger modules for commercial vehicles. These components are crafted using both traditional and innovative technologies, providing versatile solutions for electrical and electronic devices. Eaton’s supercapacitors are available through TME, offering customers access to high-quality components for diverse applications.

Supercapacitor Series and Features by Eaton

Eaton’s supercapacitors stand out due to their diversity. The product range includes capacitors with varying capacitances, sizes, and voltage ratings, all designed to meet different performance requirements. Eaton’s portfolio features components with low ESR, high voltage ratings, and wide thermal tolerance, suitable for a variety of applications.

Electrolyte Composition and Performance

Eaton’s supercapacitors are categorized by their electrolyte composition, which directly affects their performance:

Propylene Carbonate: Used in series like B, HB, KR, and KW, these capacitors are environmentally friendly and non-flammable, with excellent thermal properties and a voltage rating up to 2.5V. They have a thermal operating range from -25°C to 70°C.
Acetonitrile: Found in series such as HV, XV, and XL60, acetonitrile-based capacitors offer higher capacitance (up to 80% more), increased voltage (up to 2.7V), and lower ESR. They can also tolerate temperatures as low as -40°C but are restricted due to toxic emissions when exposed to fire.
Eaton Proprietary Formulations: Capacitors in the TV, XT, and XL60 3.0V series use Eaton’s patented electrolytes, providing high capacitance, low leakage, and low ESR, with voltages up to 3V.
Overview of Eaton Supercapacitor Series

Eaton’s supercapacitors are divided into different series, each optimized for specific applications:

Standard Cylindrical Supercapacitors: Series like B, HB, and HV are ideal for UPS, power supplies, and energy systems. The HB and HV series provide higher capacitance (up to 110F) and are suitable for renewable energy systems, meters, and sensors.
Hybrid Technology: Eaton’s hybrid capacitors combine capacitor-like electrodes with battery-like electrodes, resulting in a longer lifespan (up to 20 years). They are ideal for remote devices like sensors and industrial systems that require high energy in short bursts.
Miniature and Low-Profile Versions: Eaton also offers compact supercapacitors with capacitance up to 5F, perfect for IoT applications. The PHVL series, in particular, features ultra-low leakage current and operates within a thermal range of -40°C to 85°C, making it suitable for backup power and RTC clocks.
High-Capacitance and Operating Voltage: The XL60 and XV series are designed for high-power applications like regenerative braking in electric vehicles (EVs) and industrial circuits. The XL60 series, offering capacitance up to 3kF at 2.7V DC, is ideal for applications requiring high current intensity.
XLR Packages: Eaton’s XL60 capacitors are available in XLR packages, offering capacitance from 160F to 500F and voltages between 16.2V and 51.3V DC. These are suitable for industries like transportation and heavy machinery, reducing operational costs and improving system stability.
Applications

Supercapacitors serve in two primary application categories:

High-Power Applications: These include regenerative braking systems in EVs, uninterruptible power supplies (UPS), and industrial power systems, where supercapacitors deliver quick bursts of energy.
Compact Power Sources: Supercapacitors also provide auxiliary power for IoT devices, remote sensors, and communication modules, where they store small amounts of energy for periodic use.
Conclusion

Eaton’s supercapacitors offer a range of solutions for energy storage, power delivery, and backup applications. Their products are versatile, high-performing, and durable, making them ideal for industries like renewable energy, IoT, and electric vehicles.
