Mica and PTFE Capacitors
Mica and PTFE capacitors are components that are typically found in electronic and electrical circuits. These capacitors are composed of two plates that are separated by a dielectric material. The mica capacitors use either mica or glass foil as the dielectric material, while the PTFE capacitors use polytetrafluoroethylene (PTFE) as the dielectric. The CDV30FH121FO3F is a mica and PTFE capacitor series that is manufactured by Cornell Dubilier. It is a radial leaded and through-hole mount capacitor. It is composed of two metal foil plates that are encapsulated in a black PTFE material and dipped in an epoxy resin. The PTFE material provides superior temperature stability and the epoxy resin provides superior protection against moisture and other contaminants. These capacitors are designed for applications that require excellent stability and reliability. They are used in a variety of applications including switching power supplies, LED lighting, and low-noise amplifiers. The CDV30FH121FO3F series provides stable voltage across a wide temperature range (-55°C to +110°C). Additionally, the capacitors offer excellent dielectric strength and durability. The working principle of the CDV30FH121FO3F series capacitors is simple. When an alternating current (AC) is applied to the capacitor, an electrical field is established across the plates. The electrical field causes electrons to be displaced in one direction, creating a charge on the plates. The dielectric material acts as an insulator, preventing the electrons from flowing between the plates and creating a voltage drop. The amount of charge on the plates is determined by the distance between the plates, the size of the plates, and the dielectric material. As the charge on the plates increases, the voltage between the plates increases. This increase in voltage is known as "capacitance". The capacitance, in turn, determines the amount of voltage that can be stored by the capacitor. The CDV30FH121FO3F series capacitors are ideal for applications that require excellent stability and reliability. The combination of mica and PTFE provides superior temperature stability and the epoxy resin offers superior protection against moisture and other contaminants. The capacitors have a wide temperature range and offer excellent dielectric strength and durability. With their superior performance and reliability, these capacitors are an ideal choice for a variety of electronic and electrical circuit applications.
