Film Capacitors

Film capacitors, also known as film dielectric capacitors or plastic film capacitors, are one of the most common types of capacitors available today. They are widely used in electronic equipment such as televisions, radios, audio equipment, computers, and other applications such as motor drives and medical equipments. These capacitors are very resilient, reliable, and have long operating lifetimes.

MMWA05P33K Application Field and Working Principle

Film capacitors are used to store electrical charges and then discharge them into a circuit as needed. The MMWA05P33K film capacitor is a medium performance dielectric capacitor from KEMET, a well-known capacitor manufacturer. It’s a tantalum polymer hybrid capacitor with a P33K dielectric, which is an organic polymer commonly used in the electronics industry. It features a high voltage rating (3.3 V) as well as low ESR. This makes it ideal for high frequency applications.

The MMWA05P33K performs well in applications that require moderate temperature stability and low ESR, including voltage regulation and power supply ripple filtering in audio amplifiers, switching power supplies and motor drivers. It is suitable for high frequency application such as RF antenna matching and tuning circuits, broadband and RF amplifiers, and communications circuits.

The working principle of the MMWA05P33K film capacitor is simple. Two conductive layers of metal (anode and cathode) are separated by a dielectric. When an electrical voltage is applied, it causes an electric field to be established across the dielectric. The electric field creates an attraction force between the two conductive layers that increases the capacitance. This is known as the dielectric effect.

The MMWA05P33K is rated for a maximum operating temperature of 85°C, so it can handle some higher temperature applications. Its low ESR also makes it resistant to distortion and noise, meaning it\'s an ideal choice for critical audio and video applications.

Overall, the MMWA05P33K is a superior film capacitor for applications such as voltage regulation, power supply ripple filtering, RF antenna matching, and broadband audio and video applications. Its high voltage rating, low ESR, and high temperature stability make it perfect for a variety of different applications.
