Film capacitors are electronic components that are common in a wide range of electrical and electronic applications. By using a thin sheet of dielectric material between two conducting plates, they provide a large capacitance in a small package. Typical values range from a few picofarads to hundreds of microfarads. The C274AC34300SA0J is a type of film capacitor designed for high-frequency, high-voltage operation.

The C274AC34300SA0J is a metallized polyester film capacitor manufactured by United Chemi-Con. It is a surface-mount version with dimensions of 27.4 mm by 4.3 mm. It has a capacitance of 3.3μF, making it well-suited for applications where a low level of capacitance is desired. The C274AC34300SA0J is rated for a working voltage of 300V AC, making it suitable for use in medium and high voltage circuits. It is mostly used in the commercial, industrial and medical industries.

The C274AC34300SA0J has a high self-healing capability due to its metallized construction. The two metallic layers are separated by a thin dielectric film. When the capacitor is subjected to a high voltage, the dielectric may break down and create a small electric arc. This creates a current path through the dielectric, restoring the capacitor\'s capacitance. The self-healing properties of the C274AC34300SA0J make it well-suited to use in AC circuits where the voltage level can fluctuate significantly.

The C274AC34300SA0J has a temperature coefficient of 25 ± 10% ppm/°C, making it suitable for a wide range of temperature ranges. The capacitor also features a UL94V-O rating, making it suitable for use in demanding environments. The capacitor is also resistant to a variety of stresses, including moisture, vibration and shock.

The C274AC34300SA0J is typically used for filtering and bypassing high-frequency signals in switch-mode power supplies, audio amplifiers and other electronic circuits. Its low capacitance and high voltage rating make it suitable for use in narrowband and wideband radio frequency circuits. The capacitor can also be used for surge suppression, phase shift and snubber circuits.

In summary, the C274AC34300SA0J is a surface-mount film capacitor with a capacitance of 3.3μF and a rated voltage of 300V AC. It is well-suited for use in high-frequency, high-voltage applications, such as switch-mode power supplies and radio frequency circuits. It is also resistant to a variety of environmental factors, making it suitable for use in demanding environments.
