The TDK Group has launched a new series of two-terminal Aluminum Electrolytic Capacitors from EPCOS, namely the B43640* and B43644*. These capacitors are designed with an ultra-compact form factor, offering a smaller size compared to previous models with similar voltage and capacitance ratings. The dimensions range from 22 x 25 mm to 35 x 55 mm (diameter x height), making them ideal for space-constrained applications.
Both series feature exceptional ripple current handling capabilities, ensuring reliable performance in high-demand environments. The B43640* series operates at voltages between 200 V DC and 450 V DC, with capacitance values ranging from 82 μF to 3300 μF. It offers a continuous operating life of up to 2000 hours at 105°C. On the other hand, the B43644* series is suitable for higher voltage ranges, from 200 V DC to 500 V DC, with capacitances from 39 μF to 2700 μF, and can operate continuously for up to 5000 hours at 105°C.
Thanks to their compact design, these capacitors are well-suited for use as link capacitors in compact inverters, photovoltaic inverters, and industrial power supplies. Their small size and high performance make them a preferred choice for modern electronics where space efficiency and reliability are critical.
Key features and benefits include:
- Ultra-compact design, available in sizes from 22 x 25 mm to 35 x 55 mm (diameter x height)
- Excellent ripple current capability for stable and efficient operation
- Long service life under continuous operation at 105°C (up to 5000 hours)
- Ideal for high-voltage applications in renewable energy systems, industrial equipment, and more
These new capacitors from TDK’s EPCOS division represent a significant advancement in compact, high-performance power electronics components. Whether you're designing next-generation inverters or optimizing power supply units, the B43640* and B43644* series offer a reliable and space-saving solution.
Water-cooled Capacitor is supercapacitor is a capacitor with a capacity of thousands of farads.According to the principle of capacitor, capacitance depends on the distance between the electrode and electrode surface area, in order to get such a large capacitance, as far as possible to narrow the distance between the super capacitor electrode, electrode surface area increased, therefore, through the theory of electric double layer and porous activated carbon electrode.
