Film Capacitors

Film capacitors are electrical components made of a dielectric film (or thin insulation layer) as the dielectric medium, aluminium or zinc as metal electrodes applied on each side of the dielectric film. They are very common components of electrical circuits, used for temporary storage of electric energy, filtering, coupling and blocking of large and low impedance signals.

C878AF14400ZA4J application field and working principle

The C878AF14400ZA4J is a film capacitor. This type of film capacitor is designed to meet specific needs in a variety of applications. Its attractive features include its small-sized, lightweight design, as well as its high-quality output of a very low equivalent series inductance, superior sound quality, and improved frequency response. This makes it perfectly suited for usage in sensitive audio signal circuits in amplifiers and preamplifiers. It is also suitable for other applications needing a high-precision, low-intrusive filtering or blocking characteristics.

The C878AF14400ZA4J utilizes a PTFE conical-shaped film dielectric, covered in a polyester film, as it’s main material. This provides an insulation that is both durable and resistant to chemical attack and heat. It supports values of up to 400V with an insulation resistance of 10 G mm. It is further complemented with a 0.1uF capacitance, with a 5% tolerance. This, accompanied with a 110mOhm ESR as well as an 85dB RF shielding makes the capacitor extremely stable and accurate in it\'s operations.

The C878AF14400ZA4J utilizes a 5.3mmx12.5mm hole size, and is a radial-lead capacitor. This means that it uses metallic lead wires with insulation for connection to the terminals, and its cylindrical-shaped encapsulation. It also employs a unique design for dissipating heat produced during electrical discharge, making it suitable for long lifetime applications.

Ultimately, the C878AF14400ZA4J is an ideal film capacitor that provides excellent performance across a variety of applications. It’s heavy resistance to temperatures and EMI makes it ideal for audio applications, and its durability and availability in small sizes makes it an attractive option for limited space applications.
