Frequently Asked Questions

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.

High Temperature Ceramic Capacitors

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.

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.

Do I Need Highly Reliable, High Temp Capacitors?

The main goal of high temperature capacitors is to allow for stable performance of electrical equipment at high temperatures. They are also involved heavily in applications that require a high level of reliability. Though there are a wide variety of different capacitors and types of technologies that are available depending on the needs of the situation, only a few are available that can operate in a reliable way once temperatures become elevated. 

High temperature capacitors made out of materials like ceramic or tantalum are usually employed when an application begins to operate at a temperature near or above 350 degrees Fahrenheit.
