BN104I0333K--

Film capacitors, also known as DC link or AC line capacitors, consist of an electrically conductive material sandwiched between two layers of insulating film. In their most common form, they consist of a high-k dielectric layer between two metal conductors, either plates or strips. The dielectric layer, also known as a dielectric luminescent film, is typically an organic material, such as polypropylene, polyester or polyethylene terephthalate.

BN104I0333K is a film capacitor manufactured by TDK Corporation. This model is specifically designed for High Frequency applications, with High Current Capability. The BN104I0333K capacitor utilizes a molded case and a non-polarized design; this means that the capacitor can be used in either AC or DC applications, without any special consideration for its orientation. The capacitor also uses a metal-polymer composition as its dielectric, making it ideal for high-frequency applications.

The working principle of a film capacitor is very simple. Capacitance is created by the electrical field between two opposing surfaces, separated by an insulating material. A voltage is applied across the conductor terminals, establishing an electric field between the conductors. This field creates an electric charge on the inside and outside plates, which stores electrical energy. The stored energy can then be released gradually, providing a steady current over time.

The BN104I0333K film capacitor is an appropriate choice for a variety of high-frequency application as it offers excellent frequency response, high current capability and low ESR (Equivalent Series Resistance). Due to its low parasitic inductance, it is ideally suited for applications requiring low frequencies ranging from 1MHz to 1GHz, such as TV/PC audio, automotive audio/video, audio power amplifiers, PLC inverters and more. It also provides a low EMI (electromagnetic interference) as well as being reliable under harsh electrical environments.

In addition to the high-frequency capabilities, the BN104I0333K has demonstrated superior aging performance. It has a low temperature coefficient and can withstand a temperature range from -25°C to +105°C. This makes it suitable for applications under extreme temperature variations, including automotive and industrial applications.

The BN104I0333K film capacitor is a reliable solution for a wide range of high-frequency applications due to its superior electrical properties. It combines a reliable metal-polymer dielectric composition with excellent frequency response, high current capability and low ESR. This makes it a suitable choice for applications under extreme temperature variations, including automotive and industrial applications.
