Film capacitors are a type of capacitor featuring a dielectric material that is wrapped in thin layers of metal or other conductive material. They are popularly used in applications that require reliable electrical performance in even the most extreme conditions. The BN074E0333K, for example, is a film capacitor that could be used in any networked, radio, telecom, or computing device.

The BN074E0333K is a 4V, 2000μF (microfarad) film capacitor with a temperature range from -55°C to +105°C. It provides excellent performance in low- and high-temperature environments, making it capable of operating from extreme temperatures to near room temperature. It also has low ESR (Effective Series Resistance) and ESL (Equivalent Series Inductance), making it suitable for many practical applications. The BN074E0333K is a radial-leaded film capacitor, meaning that it is constructed with two insulating layers of polymer film enclosed between the positive and negative contacts.

The BN074E0333K is most often used in applications where noise filtering is required, such as in switching power supplies. It is also used in applications where reliable, high-voltage protection and surge suppression are needed. The BN074E0333K’s high capacitance and wide temperature range make it suitable for use in pulse and RF applications. The capacitor also offers series connection and terminal symmetrical construction, reducing stray fields, making it suitable for applications that require strong noise suppression, like EMI (Electromagnetic Interference) or ESD (Electrostatic Discharge) protection.

The BN074E0333K’s working principle is based on the concept of capacitance. When two conductors are separated by an insulating material, capacitance is created. This capacitance allows electrical charge to be stored in the capacitor. When an alternating voltage is applied to the capacitor, the charge is redistributed, resulting in a voltage drop. The capacitance of a film capacitor is determined by its shape, size, and dielectric material.

The ETFE (ethylene tetrafluoroethylene) material makes the BN074E0333K ideal for applications due to its excellent electrical insulation, good thermal conductance, high chemical and weather resistance, and superior chemical stability. The film insulation also provides high and reliable thermal and electrical stability over a wide temperature range.

The BN074E0333K is an excellent choice for projects that need reliable electrical performance in extreme conditions. Its wide temperature range and low ESR and ESL make it suitable for RF and pulse applications. Its ETFE insulation provides high and reliable thermal and electrical stability, making it the perfect choice for applications that require strong noise suppression.
