TFSQ0402C0H1C0R8WT Capacitors

Thin Film Capacitors

Thin film capacitors, also known as TFS capacitors, are extremely small capacitors made with a thin film of conductive material, such as aluminum or copper, deposited on a substrate. The inner surface of the substrate is generally made of an insulating material, such as aluminum oxide. This combination of materials forms the dielectric of the capacitor and it is the dielectric that determines the characteristics of the capacitor.

TFSQ0402C0H1C0R8WT is a type of thin film capacitor. It is of the 0402 chip size and has a high-k dielectric of 1000-5000 K per square centimeters. It also has a working voltage of 16V DC, a capacitance range of 0.025-0.22uF, and a temperature coefficient of +30∕-30ppm/℃.

Application Field

The TFSQ0402C0H1C0R8WT is used in numerous applications including automotive, medical, and industrial electronics. It is particularly well suited for telecom, cellular, and satellite communications. Due to its small size and low profile, the TFSQ0402C0H1C0R8WT is ideal for use in high frequency applications, such as clocks, filters, oscillators, and signal processing.

Some of the more common applications that use the TFSQ0402C0H1C0R8WT are mobile phones, two-way radios, GPS receivers, echo sounders, GSM systems, wireless LANs, routers, and digital electronics.

Working Principle

The TFSQ0402C0H1C0R8WT capacitor works by creating an electric field between two conductive plates, commonly termed the anode and the cathode. The electric field causes a charge separation, which gives the capacitor a potential difference and thus an ability to store energy.

As the electric field builds, a dielectric material, such as aluminum oxide, acts as an insulator and prevents direct current from flowing between the plates. When an alternating current is applied, however, the electric field changes constantly and allows the current to pass through and store the energy.

The size of the TFSQ0402C0H1C0R8WT capacitor determines the amount of energy it can store and the frequency at which it can be used. The higher the capacitance the greater the amount of energy that can be stored and the higher the frequency at which it can be used.
