Mica and PTFE CapacitorsMica and PTFE capacitors are non-polarized capacitors made up of thin layers of mica and polytetrafluoroethylene (PTFE) sandwiched between metal layers.The mica material is generally made of silvery, thin-film mica dielectric, with thickness ranging from 0.003-0.005”. The mica dielectric has the capability of withstanding high temperatures and high humidity levels while providing high capacitance stability over a wide temperature range.The PTFE is comprised of three layers: an electrically conductive layer made of stainless steel, a coated, dielectric layer made of polytetrafluoroethylene, and an inner layer made of aluminum. This combination of materials enables the capacitors to have a low dielectric constant, allowing them to be used in environments with very high heat and humidity.The CDV30FF681GO3F is a mica and PTFE capacitor specifically designed for use in high-temperature, high-humidity environments. It has a rated operating voltage of 250 volts and an operating temperature of up to 155°C. Additionally, it is highly resistant to moisture, has a low equivalent series resistance, and has a very low dissipation factor.The CDV30FF681GO3F is primarily used in applications such as high-power transformers, AC motor drives, UPS systems, PV solar inverters, and HVAC equipment. Due to its high temperature and humidity resistance, it is well-suited for power applications in which higher operating temperatures may be encountered.The working principle of a mica and PTFE capacitor is based on the concept of an electrical double layer which is formed by the mica and dielectric layers. This double layer stores charge and acts as an insulator. In practice, when a voltage is applied across the capacitor plates, electrostatic force is generated and causes the mica and dielectric layers to store electrical energy in the form of an electric field. The electric field is then used to separate the positive and negative charges. This separation of charges increases the capacitance of the capacitor.Due to its ability to withstand high temperatures and high humidity levels, the CDV30FF681GO3F is a great choice for many different applications. It offers excellent electrical stability and reliability, making it an ideal choice for harsh and demanding environments.
