Mica and PTFE materials have long been used in capacitors due to their electrical properties. With their low dielectric constant, high temperature and voltage ratings, and extremely low loss characteristics, they are popular in applications requiring stable capacitors. The CD5FY391GO3 is a mica and PTFE capacitor that offers superior performance in temperatures ranging from -55°C up to 125°C. 

The CD5FY391GO3 utilises a three-layer design consisting of a PTFE sheet, a mica sheet, and an electrolyte. The PTFE sheet acts as the dielectric layer between the electrically conductive plates. The mica sheet acts as a structural support and provides extra rigidity, while the electrolyte provides a consistent charge distribution throughout the capacitor. Together, these three layers create a capacitor with a higher rated voltage and temperature capability, as well as a longer life expectancy than other capacitors.

This capacitor is mainly used in applications where high temperature and stability grade are essential. Examples include industrial and military applications such as motor drives, lighting systems, electric arc welding systems, radar systems, and avionics equipment. Furthermore, due to their low dielectric constant, they can be used in devices where high frequency signals are present, and in power supplies where high repetition rate power-cycling is necessary.

Due to their superior temperature and voltage ratings, CD5FY391GO3 capacitors are often specified by OEM designers. Their low inductance allows for high repetition rate power-cycling, while their low loss characteristics make them ideal for use in high temperature applications.

On top of all this, the mica and PTFE construction also provide reliable and desirably operation in extreme temperatures. Even in applications where extreme temperatures is a necessity, the capacitor can perform reliably without altering its capacitance and charge distribution.

In conclusion, the CD5FY391GO3 mica and PTFE capacitor is highly sought after due to its superior performance in temperatures ranging from -55°C up to 125°C. Its low dielectric constant, high temperature and voltage ratings, and low inductance make it the perfect choice for applications that require extreme temperature operation. Furthermore, its solid and reliable construction provides reliable operation and a long life expectancy, making it a favored choice amongst OEM designers and equipment manufacturers.
