Mica and PTFE capacitors are renowned for their high precision, stability, and reliability. These capacitors utilize mica, a naturally occurring mineral, and PTFE (polytetrafluoroethylene) for their dielectric materials, ensuring minimal loss and high tolerance. Their unique construction makes them ideal for high-frequency and RF applications.

Manufacturers often choose mica and PTFE capacitors for critical applications, including communication systems, aerospace, and medical devices, where exact capacitance and stability are paramount. Their ability to function efficiently in a wide range of temperatures further enhances their suitability for demanding environments.

These capacitors are available in various form factors, including surface mount and through-hole designs, and are supplied by prominent manufacturers such as AVX, Vishay, and Cornell Dubilier. Leveraging their exceptional performance characteristics, these capacitors support both low and high-voltage operations, making them versatile components for advanced electronic designs.
