Film capacitors, also known as plastic film capacitors, are named for their dielectric film material which provides superior insulation and strength compared to other types of capacitors. They are mostly used in AC applications, where their ultra-low ESR (effective series resistance) makes them ideal for a wide range of applications due to their easy-to-use design and wide range of power levels. The BN274K0435K (hereafter referred to as the BN274K) is one such series of capacitors that is especially well-suited for demanding applications due to its low losses, high reliability, and low temperature drift.The BN274K is an aluminum electrolytic capacitor, which means that it utilizes a thin oxide film deposited chemically onto an aluminum foil (the electrode) to form the dielectric layer. This film offers excellent electric characteristics at high frequencies and reduces the ESR and power losses of the capacitor. The aluminum foil is kept under tension in the package to prevent it from buckling due to the pressure of the electrolyte inside. As an added benefit, the aluminum oxide film also acts as a self-healing mechanism, as the electric current passing through the capacitor will help to replenish the oxide layer when it becomes damaged.The BN274K series of capacitors is designed for AC applications such as motor control, switch-mode power supplies, and lighting. This makes them perfect for these types of applications due to their low losses and excellent heat tolerance, which allows them to maintain their performance even when the surrounding temperature rises. The series is also equipped with a high capacitance range from 470nF to 3200nF, and can handle up to 630V. This makes them a very cost-effective solution when used in high-power applications requiring high-voltage ratings.The BN274K is also equipped with a very low ESR value (0.02 Ohms) which helps reduce power losses and improve power efficiency. This allows for higher efficiency in motor control and switch-mode power supplies and can help reduce energy costs. In addition, the capacitors have a wide operating temperature range of -60°C to +105°C, making them suitable for use in extreme-temperature environments.Overall, the BN274K series of aluminum electrolytic capacitors offers a wide range of features and benefits that make them a great choice for a wide range of AC applications. Their low losses and high reliability make them well-suited for motor control and switch-mode power supplies, while their wide temperature range allows them to be used in extreme-temperature environments. Furthermore, their wide capacitance range makes them cost-effective for high-power applications requiring high-voltage ratings, and their low ESR value helps improve power efficiency and reduce energy costs.
