Film Capacitors: Application Field and Working Principle of B32653A1822J000

Film capacitors, also known as plastic film capacitors, are devices generally used for signal and energy storage. These cellulose- and polymer-based components are ideal for a range of applications, ranging from low-noise to industry-standard systems, due to their long-lasting performance and reliability. The B32653A1822J000 model, which belongs to the EPCOS B32653 series, is designed specifically for higher frequency applications requiring high-stability capacitors suitable for high-current and high-speed solutions, such as power supplies, inverters, CCTV, etc. This model stands out as a versatile, robust, and low-distortion capacitors, enabling engineers to build reliable systems with precise and accurate performances and inputs.

Construction and Features

The construction of the B32653A1822J000 is based on PP film with coating and wrapped in Mylar, a special plastic film material. This powerful component has numerous advantages, with designated features namely: rated voltage (an insulation voltage of 250V) withstanding up to 300V for 2000 hours before degradation, a rated capacitance of 18000 pF, a tolerable range of ±20%, an insulation capacitance of 600V for 10V probing, and standard dielectric dissipation factor of 0.3%. Moreover, the B32653A1822J000 has impressive temperature capability, operating at a temperature range between -40°C and +105°C.

Application Field

The B32653A1822J000 is a powerful film capacitor that, given its low-distortion performance and reliability, serves a wide range of applications. One of the key features that make it so attractive is its ability to be used in high-speed solutions. This makes it ideal for motor control, CCTV, inverters and UPS systems, and other consumer electronics and power supply applications. It is also suitable for audio, lighting controls, radio frequency (RF) amplifiers and antennas.

Working Principle

Film capacitors, and the B32653A1822J000 in particular, work based on Faraday’s law: “When voltage is applied across a conductor, an electric field is created, which induces a counterforce across the conductor”. This principle refers to the electrostatic action, where electricity is stored separating negatively and positively charged particles on two parallel conductors. The B32653A1822J000 consists of Mylar film and layers of metal electrodes coated in resin and wound together. When excess electrons (negative charge) are drawn from one electrode onto the other and stored on one side, this creates the basis for energy storage. When an external voltage is applied, these electrons (the charging current) travel from one electrode to the other until the capacitor achieves its rated capacity, allowing energy to flow as the system requires.

Conclusions

The B32653A1822J000 is a highly reliable and versatile film capacitor that can be used in various applications, such as motor control, audio, radio frequency (RF), etc. Its powerful features, including rated voltage (an insulation voltage of 250V) and temperature capability (operating at a temperature range between -40°C and +105°C), makes it the perfect choice for engineers designing reliable systems with precise and accurate inputs. By relying on Faraday’s law, this component stores energy separating negatively and positively charged particles, building the basis for energy flow as needed.
