Mica and PTFE capacitors are used in many applications, including power supplies, amplifiers, filters, and other industrial and commercial applications. MC12FF470J-F is an example of a mica and PTFE capacitor specifically designed for applications that require an extremely low equivalent series resistance (ESR), high surge voltage, and high ripple current capabilities.The main features of the MC12FF470J-F capacitor are its non-liner dielectric properties, which enable it to operate with an extremely low equivalent series resistance of 1.2 ohms, a surge voltage rating of 4.7 kilovolts (kV) and a ripple current rating of 10 amperes. This combination of features makes the MC12FF470J-F ideal for use in high frequency switching power supplies, high voltage switching amplifiers, general audio amplifiers, and even as an energy storage asset.The working principle of the MC12FF470J-F capacitor is based on its non-linear dielectric properties. A mica and PTFE capacitor consists of two metal plates with a mica dielectric in between. When a voltage is applied across the capacitor, an electric field is created and the mica layer changes its dielectric property according to the applied voltage. This nonlinear effect is known as dielectric hysteresis and it has an important influence on the capacitor’s performance in a high frequency application.The MC12FF470J-F capacitor also features a low capacitance rating of 0.47 microfarads. This low rating is what gives the capacitor its exceptional low equivalent series resistance performance. In addition, the capacitor also has a high maximum operating temperature of 105°C, allowing it to operate reliably in temperatures far hotter than those in which most other capacitors will fail.The MC12FF470J-F capacitor is also designed to be highly reliable and robust. It is constructed out of a thick, laminated film dielectric with 25 layers of mica sandwiched between layers of PTFE and polytetrafluoroethylene (PTFE). This construct makes it highly reliable and resistant to thermal shock, which is an important factor in high voltage and current applications.In summary, the MC12FF470J-F capacitor is an ideal choice for use in high voltage and current applications that require an extremely low equivalent series resistance, high surge voltage, and high ripple current capabilities. Its non-linear dielectric properties and rugged construction enable it to operate reliably in temperatures far hotter than those in which most other capacitors will fail. It is an optimal choice for power supplies, amplifiers, filters, and other industrial and commercial applications.
