Frequently Asked Questions

Find answers to the most frequently asked questions about our products and services.
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 a trimmer capacitor and what is it used for?

A trimmer capacitor is a variable capacitor designed for precise adjustment of capacitance in electronic circuits. It is typically used in RF applications such as oscillators, filters, impedance matching, and crystal trimming, where fine tuning is required to optimize performance.

What are the key advantages of Exxelia trimmer capacitors?

Exxelia trimmer capacitors offer high stability over time, low temperature coefficient, and minimal capacitance drift. They also feature a high Q factor, ensuring low energy losses and excellent performance in high-frequency applications. Many models include multi-turn adjustment for high resolution tuning and a self-locking mechanism for reliable settings.

Which types of trimmer capacitors does Exxelia provide?

Exxelia offers a wide range of trimmer capacitors, including air dielectric, sapphire dielectric (GHz range), non-magnetic versions, high-voltage models, and SMD chip trimmers. These different technologies are designed to meet various requirements such as high frequency performance, compact integration, or operation in harsh and sensitive environments.

What performance levels can be expected in terms of frequency and voltage?

Depending on the series, Exxelia trimmer capacitors can operate at frequencies up to several GHz and support working voltages from 250 VDC up to 5000 VDC. Sapphire-based models provide very high self-resonant frequency and excellent Q performance, making them suitable for demanding RF and microwave applications.

Are Exxelia trimmer capacitors suitable for harsh or critical environments?

Yes, many Exxelia trimmer capacitors are designed to withstand harsh conditions, including vibration, shock, and extreme temperatures (typically from -55°C to +125°C). Non-magnetic versions are available for applications such as MRI and other sensitive environments, while hermetic and sealed models provide resistance to moisture, dust, and cleaning processes.
