Film capacitors are a type of capacitor that uses a thin film rather than two metal plates to store electric energy. They are widely used to provide reliable capacitance values and to reduce the size of capacitor networks. One of the most widely used types of film capacitors is the C274AC35120SA0J capacitor. It is an axial-lead, dry-electrolytic, double-layer capacitor that is well suited for AC operation across a broad frequency range.

The C274AC35120SA0J capacitor is typically used for applications that require low capacitance values ranging from 0.1 microfarads to 100 microfarads. It is ideal for power supply filtering or DC blocking in AC circuits. It is also suitable for use in the resonant circuits of AC applications such as switching power supplies, LED lighting, LED lamps, and other high-frequency applications.

The key feature of the C274AC35120SA0J capacitor is its maximum AC ripple current of 35A. This rating ensures that it is capable of handling large currents without experiencing excessive heating. The ripple current also helps minimize the amount of power Factor Correction (PFC) required, which increases efficiency and reduces costs. Additionally, the capacitor can operate at temperatures of up to 85℃, making it suitable for use in environments where higher temperatures are common.

The C274AC35120SA0J capacitor works by allowing electric charges to pass through its two dielectric layers, a plastic film and an aluminum film. These two dielectric layers are connected by a feed-through wire which is also connected to two lead-out terminals. When an AC voltage is applied to the capacitor, the electrical current passes from one layer to the other through the feed-through wire, thereby transferring electric charge and creating a capacitor.

Because of the dual dielectric layer design of the C274AC35120SA0J capacitor, the device exhibits low ESR and low dissipation, providing greater efficiency and improved power quality. The capacitor also offers excellent frequency stability and tolerances up to ±20%. Furthermore, the low inductance and load life of the device make it a popular choice for use in high power circuits.

The C274AC35120SA0J capacitor is ideally suited for high-power applications where a low-cost, efficient, and reliable capacitor is required. Its wide operating temperature range and high maximum AC ripple current rating make it an excellent choice for AC operation across a broad frequency range. Additionally, its low ESR, low clamping voltage, and long load life make it a cost-effective solution for high-power circuits requiring reliable and efficient capacitance.
