Introduction

Film capacitors, also known as foil capacitors, are specialized electronic components that consist of two slightly separated sheets of metal and electrical insulation, or "dielectric", sandwiched between them. 170394J630XF is one of the film capacitors, it differs from other capacitors and is known for its superior high voltage and current capacity, its ability to withstand high temperatures and its good temperature and frequency stability.

Application Field

The 170394J630XF film capacitor is mainly used in the electronics and communications industry. It is widely used in radio frequency (RF) applications such as HF, VHF, UHF, frequencies and high voltage DC-AC inverters. Its superior temperature and frequency stability makes it ideal for applications such as automotive audio systems, radio transceivers and high voltage power amplifiers.

Working Principle

The basic principle of the film capacitor’s operation is the combination of capacitive and dielectric principles. The two slightly separated sheets of metal act as a capacitor plate, whereby they store and release electrical energy when charged and discharged. The dielectric material, which is sandwiched between the two metal plates, stores the charge indefinitely until the voltage is discharged again. When the capacitor is connected to a power source, the dielectric acts like an insulator and does not allow the electrical signal to be shorted or discharged.

Product Features

The 170394J630XF Film Capacitor is designed for operation in a wide range of temperature and voltage conditions. It features a temperature coefficient of 0.03 per degree Celsius and a voltage rating of 250V to 630V. The operating temperature of the capacitor is -55°C to +105°C. The capacitor offers high reliability for shock and vibration tests, having a maximum Vibration of 30g and shock of 180g. It is also equipped with a tinned metal case that is designed to dissipate the heat generated during operation and prolong the life of the component.

Advantages

Compared to other types of capacitors, the 170394J630XF Film Capacitor offers several advantages. It has a long lifespan due to its low leakage current and superior thermal stability, and high performance due to its superior insulation characteristics. The capacitors also offer a stable performance at high frequencies, which makes them ideal for many HF applications. The component is also highly reliable due to its superior shock and vibration resistance. It is also small in size, making it easy to install and ideal for applications in tight spaces.

Conclusion

The 170394J630XF Film Capacitor is one of the most widely used types of capacitors. It is highly reliable and suitable for applications in the electronic and communications industry such as HF applications, automotive audio systems, radio transceivers and high voltage power amplifiers. The high performance and superior insulation characteristics of the capacitor make it ideal for demanding applications. It can also withstand high temperature and vibration conditions, and offers long lifespan due to its low leakage current.
