Film Capacitors

A film capacitor, also known as polymer film capacitor or foil capacitor, is a capacitor with a very thin insulating film of plastic or metal as the dielectric and thin metal foils as the electrodes. It is usually wound up in a cylindrical package with metal or plastic housing. A film capacitor is a type of capacitor characterized by small size, light weight, superior insulation, wide capacitance range, high stability, and long life expectancy.

QYX1H682KTP1FD Application Field and Working Principle

The QYX1H682KTP1FD film capacitor is a non-inductive, surface-mountable capacitor widely used in high-precision electronic devices, such as oscilloscopes, logic circuits, and digital devices. It is mainly used in DC blocking, bypassing, and coupling applications. The QYX1H682KTP1FD film capacitor consists of two parallel metal plates separated by a polyethylene naphthalate film material as the dielectric. The polyethylene naphthalate is a type of polyester film material and is thin and very dielectric.

The QYX1H682KTP1FD film capacitor stores energy in the form of an electric field between the two metal plates. The thickness of the dielectric is only a few ions thick, allowing for a higher electric field and higher capacitor values. When a voltage is applied to the capacitor, an electric field is created between the plates and this charging process causes the electrical energy to be stored in the form of an electrostatic potential. When a voltage is removed, the electric field dissipates, releasing the stored energy.

The capacitance of the QYX1H682KTP1FD is measured in Farads, and its wide capacitance range (100pF to 1nF) makes it ideal for use in high-frequency circuit design. It has excellent frequency characteristics and its low loss factor makes it well suited for applications where high accuracy is needed, such as frequency generation and signal conditioning. It also has a high insulation resistance and is capable of withstanding high ripple currents.

The basic physical construction of the QYX1H682KTP1FD film capacitor is a very thin dielectric layer sandwiched between two metal plates. This type of construction is what gives the capacitor its high capacitance and low impedance characteristics. Additionally, the capacitor has very low self-inductance, making it an ideal choice for applications where high frequency is involved. The dimensions of the capacitor are very small, making it ideal for surface mounting in small electronic assemblies.

The QYX1H682KTP1FD is one of the most reliable and widely used film capacitors available on the market today. It is capable of operating at a wide range of temperatures from -55°C to +100°C and is ideal for use in temperature or humidity controlled environments. The QYX1H682KTP1FD offers a high level of performance and reliability and is suitable for a wide range of applications.
