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.

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

High temperature ceramic capacitors and high temperature mica capacitors are often used in situations that require a higher voltage or a higher power than normal. Because of the ways in which they are built, they can offer low ESR and excellent inrush current and ripple capabilities that other types of capacitors cannot. The only downside is that they tend to be physically larger than other types of capacitors.

The automotive industry is another area where high temperature capacitors are required. The temperature conditions can vary dramatically depending on what area of a car you’re talking about. The brake systems, the engine and the transmission are often the most temperature intensive areas.
