Film capacitors are a type of capacitor that, as the name suggests, are made from film - a thin coating of plastic film. They are widely used in many applications in the electronics industry. The DLR1P33J-F is a widely used film capacitor in the industry, and this article will discuss its application field and working principle.

Application Field

Film capacitors are widely used in industries such as telecommunications, automotive, and consumer electronics applications. In telecommunications, they are used in the data links and networking application such as T1/E1/ISDN. In the automotive industry, they are used for power management of instruments and supplies. Film capacitors are also used in consumer electronics applications such as LCD and LED TV backlight inverters, chargers, digital audio applications, and computer power supplies.

The DLR1P33J-F is a surface mount film capacitor that is designed for use in all of these applications. This capacitor has a low ESL (Equivalent Series Resistance) that is ideal for high-speed switching applications. The wide range of capacitance values allows use in different circuits. The wide capacitance range is also ideal for pulse-type noise suppression. The DLR1P33J-F is a reliable, surface mount aluminum electrolytic capacitor, providing low loss and high reliability.

Working Principle

Film capacitors work on the principle of electrochemical capacitor. This principle is based on the storage of energy in an electrical field, which is created between two metal strips separated by a thin layer of dielectric material. In the case of a film capacitor, the dielectric material is a thin layer of plastic film on top of the two metal strips. The two metal strips are electrically connected to a pair of electrical leads.

When an electrical current is applied to the two metal Strips, a charge builds up on its surface and an electrical field is generated between them. The electrical field is stored in the plastic film and operates as a capacitor, storing energy for later use. The DLR1P33J-F film capacitor incorporates this same concept of electrochemical capacitor to store energy while providing low loss, high reliability, and a wide capacitance range.
