Mica and PTFE Capacitors encompass a variety of different components, each offering its own strength in terms of reliability, temperature range, size, voltage rating, dielectric, and more. The MC12FD470G-F is a particularly popular component due to its various specs that provide an excellent fit for a range of applications. The following sections will discuss the application fields and working principle of the MC12FD470G-F mica and PTFE capacitor.

Application Field

The MC12FD470G-F mica and PTFE capacitor is primarily designed for use in extreme high temperature environments. It is rated to withstand temperatures up to 350°C, and has an insulation resistance of 500 VDC minimum. This makes it an ideal choice for use in power supplies, blocking circuits, pulse circuits, and other applications that require reliable, high temperature resistance.

The majority of applications for the MC12FD470G-F are automotive and military specified components. Its high temperature and superior insulation resistance make it ideal for use in automotive engine and military control circuitry, as well as general commercial products and military grade aircraft. It is also frequently used in circuit applications intended for nuclear reactors, spaceships, and space elevator systems.

Working Principle

The MC12FD470G-F mica and PTFE capacitor is a multi-layer device that includes a polymeric dielectric (PTFE), conductive trace-lines (metal traces), and electrodes. The interior of the device is essentially hollow, and is filled with a filler material (i.e. quartz, fiberglass, parylene). This helps isolate the elements within the device and prevent short-circuits.

As voltage is applied to the device, a polarization field is formed. This polarization field succeeds in varying the capacitor’s capacitance with the voltage. As a voltage gradient is applied, the dielectric shifts, inducing an electric field which attracts electrons. This electric field modifies the resonance frequency of the capacitance and current. The sum of the capacitance and modified frequency, when combined, is the device’s overall capacitance.

To further improve the device’s high temperature performance, the capacitor is encased in an aluminum cover. This aluminum cover also helps improve the load life of the device by dissipating heat created by operation. Additionally, the metal trace traces that are within the device are tin-cadmium coated. This helps provide additional protection from short circuit and reverse currents.

The MC12FD470G-F mica and PTFE capacitor makes an excellent choice for a wide range of applications due to its superior temperature, insulation, and load life performance. Its ability to withstand extreme temperatures, resist shorts, and dissipate heat make it an ideal choice for automotive and military applications, as well as general commercial products and military grade aircraft.
