In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
Three common options—multilayer ceramic capacitors (MLCCs), film, or aluminum electrolytic—offer advantages and disadvantages, and there are myriad variations within each category. Choosing the right type ensures the final product has enough energy storage, fits in the available space, and functions reliably for its intended use.
There are several categories of film capacitors that can impact which is right for an application: Metallized polyester film capacitors use a thin layer of metal, such as aluminum or zinc, deposited on the polyester film as the electrodes. They offer high capacitance, low ESR, low cost, and good self-healing properties.
Choosing the right capacitor for an application can make a significant difference in the performance, reliability, and efficiency of products such as power supplies for defense, aerospace, medical technology, critical energy infrastructure, or fast EV chargers.
Metallized polyester film capacitors use a thin layer of metal, such as aluminum or zinc, deposited on the polyester film as the electrodes. They offer high capacitance, low ESR, low cost, and good self-healing properties. They meet the needs of general-purpose applications such as bypass, coupling, and decoupling.
The self-healing capability is one of the main features. The capability to withstand a wide range of AC and DC voltages, together with high current and temperature, makes them suitable for many applications in the range from a few hundreds watts up to several megawatts. These are ceramic capacitors which can support ultra-high voltages up to 50 kV.
