Mica and PTFE capacitors are among the most widely used capacitors for both base and specialized applications. The CD19FD242GO3 is particularly well-suited for high-reliability industrial and military applications due to its small size, high insulation strength, and high temperature tolerance. The CD19FD242GO3 capacitor is composed of two insulated halves, one of which is a mica dielectric and the other is a PTFE-impregnated polyester film dielectric. The mica dielectric is composed of two layers of mica stacked with oxide clamps at the edges of the mica to provide a hermetic seal. The PTFE-impregnated polyester film dielectric is sandwiched between the mica sheets and insulated using a pressure sensitive adhesive or PE-HD insulation. The capacitor is then assembled into a metal case that is hermetically sealed.

The CD19FD242GO3 capacitor is primarily used in high voltage, high power, and high frequency applications. Its high insulation strength makes it ideal for use in circuit applications that require higher working voltages. It is also suitable for resonant circuits due to its low series resistance and low parasitic inductance. The high temperature tolerance of the CD19FD242GO3 makes it a good choice for applications where temperatures are expected to exceed those of conventional capacitors. In addition, the capacitor can be used in pulse and high frequency switching circuits for its high current carrying capacity and low dissipation factor.

The CD19FD242GO3 capacitor works by storing an electrical charge on its two insulating dielectrics. Each dielectric material has a unique electrical behavior; for example, mica possesses a better insulation resistance, while PTFE provides a higher dielectric constant. When a voltage is applied to the capacitor, charge is stored on both dielectrics, with the PTFE layer providing most of the charge. As current flows through the capacitor, a given amount of energy is stored, which is released when the capacitor is discharged.

The CD19FD242GO3 is a reliable and robust capacitor option for demanding industrial and military applications. Its unique combination of mica and PTFE dielectrics provides a durable, high temperature-tolerant capacitor with good insulation characteristics and low dissipation factor. The capacitor is also small in size, making it a suitable choice for applications where space is limited, such as in switch boards and circuit layouts. With its impressive set of features, the CD19FD242GO3 is ideally suited for high-reliability, high-demand applications.
