Mica and PTFE capacitors are an important component in the design of electronic circuits, and the MC18FD431G-F is especially useful for applications where reliability and performance are critical. The MC18FD431G-F is a multilayer ceramic chip capacitor that utilizes an alumina substrate and a proprietary blend of mica and polytetrafluoroethylene (PTFE) dielectric material, which is both robust and highly resistant to temperature, humidity, and stress. The MC18FD431G-F provides superior capacitance stability over temperature, enabling reliable performance across a wide temperature range. Due to its superior performance, the MC18FD431G-F is ideal for a wide range of applications such as power supplies, power converters, DC-DC converters, resonators, and multiple voltage rails.The MC18FD431G-F capacitors utilize a proprietary blend of mica and PTFE for reliable operation at extreme temperature ranges and over long-term cycle stress. The capacitor combines a thick film mica dielectric layer with a PTFE-filled epoxy resin layer. During the manufacturing process, the mica dielectric layer is heat-treated to a temperature between 500°C and 800°C in an inert gas atmosphere, resulting in exceptional stability over temperature and excellent long-term reliability. The PTFE-filled epoxy resin layer provides superior moisture and corrosion resistance, further enhancing the reliability of the device.The MC18FD431G-F is available in a wide range of capacitance values from 0.68pF to 47pF and has an operating temperature range from -55°C to +125°C. The MC18FD431G-F is non-polarized and features exceptionally low ESR values, making it suitable for use in high frequency switching applications. The capacitor is typically connected between two terminals and acts as a storage device, storing energy in the form of an electric field. When an external voltage is applied to the terminals, an electric charge is induced in the capacitor, resulting in the storage of electrical energy. The capacitor then acts as an energy reservoir, releasing the stored energy when the voltage across the terminals is discharged.In addition to its exceptional performance, the MC18FD431G-F is also very compact, making it ideal for applications with limited space. The device is hermetically sealed with a proprietary electrical discharge coating, ensuring maximum reliability even in harsh environments. The MC18FD431G-F is also RoHS compliant, making it an ideal choice for applications requiring environmental compliance.Overall, the unique blend of mica and PTFE within the MC18FD431G-F makes it ideal for a wide range of applications requiring superior performance, reliability, and environmental compliance. The device provides robust performance over a wide temperature range, reliable performance over long-term cycle stress, and exceptional low ESR, making it ideal for high frequency switching applications. With its superior performance, compact size, and environmental compliance, the MC18FD431G-F is an excellent choice for a wide range of applications.
