Film Capacitors

Film capacitors are a type of capacitor that uses an ultra-thin polyester (also called polyethylene terephthalate or PET) film as the dielectric, which is a material that the electric current passes through between electrodes. This type of capacitor has many unique characteristics, including high capacitance values, high voltage ratings, and low ESR. The PFR5471J250J11L4BULK film capacitor is a prime example.

PFR5471J250J11L4BULK Application Field and Working Principle

The PFR5471J250J11L4BULK film capacitor is designed for use in a variety of high-performance applications, including lighting, computers, audio and video, industrial control systems, and other power electronics. The capacitor’s operating temperature range is −40°C to +125°C, and its capacitance range is 0.01 to 0.47µF. The capacitor’s rated voltage is 250V DC, and its ESR is 0.10 ohms.

The PFR5471J250J11L4BULK film capacitor consists of two electrodes that are separated by the ultra-thin film dielectric. The electrodes are made of aluminum, which enables the capacitor to maintain its capacitance and low ESR characteristics over a wide frequency range. The film dielectric material insulates the capacitor and limits the electrical current that can flow through the capacitor.

The capacitor is also enclosed in a special aluminum case with a sealed top, which helps protect the inside components. The aluminum case also increases the capacitance value and provides additional electrical resistance, which helps reduce ESR, noise, and other electrical losses.

The PFR5471J250J11L4BULK film capacitor is designed for AC and DC applications. It is ideal for applications with alternating current (AC) because of its ability to optimize output and limit current waveform distortion. The thick film also helps attenuate spurious signals and reduce noise from incoming electrical signals.

When used in a DC application, the PFR5471J250J11L4BULK film capacitor helps to maintain voltage across its terminals and to reduce electrical losses. Since the dielectric material is very thin and its capacitance is very high, it can handle high voltage and current levels without deteriorating or malfunctioning. The capacitor also helps to reduce electrical noise, and it is capable of storing significant amounts of electrical energy.

In conclusion, the PFR5471J250J11L4BULK film capacitor is a high-performance capacitor that is ideal for a variety of applications. It is designed to handle high voltage and current levels, and it has a low ESR, which helps to reduce electrical losses. The capacitor also helps reduce electrical noise and attenuate spurious signals, and its aluminum case helps to increase the capacitance value and provide additional electrical resistance.
