Aluminum Electrolytic Capacitors

Exxelia distinguishes itself by engineering its own electrolytes, a unique approach that ensures unparalleled longevity in the market. Exxelia aluminum electrolytic capacitors deliver not only high capacitance values (up to 2.2F) and extended service life but also thrive under extreme temperatures and are available as catalog product or custom design.

 

Designed for high energy applications, screw terminals aluminum electrolytic capacitors are widely used into the railway, medical, UPS and charge/discharge sectors, praised for their substantial energy density and durability. Exxelia also offers the possibility to provide assembly of screw terminal capacitors banks of 4, 6, 8 or more capacitors.

 

Meanwhile, Exxelia snap-in aluminum electrolytic capacitors set industry benchmarks with their exceptional lifespan at 105°C and broad operating temperature range (-55°C to +125°C), making them indispensable for railway rolling stock, signaling equipment, solar panel inverters, and military-grade power supplies.

 

Exxelia radial leaded aluminum electrolytic capacitors range included cylindrical capacitors and rectangular low-profile flat packaging products series with operating temperature up to 125°C. They can withstand up to 50g vibrations and 92,000 ft altitude while demonstrating a long lifetime thanks to their nearly hermetic sealing, which makes them perfect for power supplies in aircraft and radar systems . This range include three rectangular low-profile flat packaging products series with operating temperature up to 125°C.

 

Finally, our axial capacitors are recognized for their wide temperature range (-55 to +145°C), high energy density, and reliability, catering to the railway, military, and power supply sectors with superior performance.

Frequently Asked Questions

Why are Electrolyte Capacitors Forward Biased?

For safety purposes, these types of capacitors need to be forward biased in their configuration. This is mainly due to the characteristics of the electrolyte that has been used in their construction. The positive terminal always needs to have a larger amount of voltage than that of the negative terminal. If the situation were reversed and the negative terminal suddenly had a higher voltage than the positive terminal (which is also referred to as reversing the voltage polarity), the aluminum material that is used as the dielectric could short circuit and become damaged. It could also overheat, which could cause a substantial leak. 

The capacitor could also vaporize, which could cause the entire enclosure to burst under the right circumstances. It is important to note, however, that this phenomenon is very rare.

High Temperature Capacitors

Exxelia has a long history providing high temperature capacitors to various industries. Several dielectrics, such as plastic (PTFE; PI; & PEI), reconstituted mica, aluminum electrolytic, tantalum and ceramic are used for manufacturing high temperature capacitors. Many are impregnated with solid thermo-setting resins such as epoxy, polyester or silicone.

These technologies provide very high stability of mechanical and electrical characteristics with temperature capabilities of -55°C to as high as +230°C, depending on the dielectric technology, and some do not require voltage de-rating. Rated voltages span from 30 VDC to as high as 60,000 VDC with capacitance ranges 100pF to 30µF.

What is the operating temperature range?

The operating temperature range generally spans from –55°C to +125°C, suitable for a wide array of industrial, military, and aerospace applications.
