Thin Film Capacitors

Thin Film Capacitors are used in a wide range of applications where high frequency performance, stability, and repeatability are required. They provide typically better electrical properties than semiconductor capacitors, both in terms of capacitance and insulation. They are used in RF circuits, switchmode power supplies, and high speed clocks, as well as in a variety of automotive, audio, and data processing applications.One example of a commercially available Thin Film Capacitor is the 12105J470FBTTR manufactured by AVX Corporation. This type of capacitor is suitable for use in RF circuits due to its stability, low loss, and excellent noise rejection. The capacitance of the 12105J470FBTTR is 470pF, with a maximum rated voltage of 12.5VDC and a maximum rated ripple current of 300mA.The construction of the 12105J470FBTTR involves the deposition of multiple layers of dielectric material, such as barium titanate, to form the basic capacitor structure. The layers of dielectric material are then embedded in a ceramic substrate to provide additional stability and reliability. The resulting capacitor has very low ESR, ESL, and resistance.The high performance of the 12105J470FBTTR makes it an ideal choice for applications requiring an outstanding combination of electrical and mechanical characteristics. It is often used in applications such as switchmode power supplies, signal conditioning circuits, and high speed clock oscillators. In addition, it is a versatile device that can be used in a wide variety of applications due to its relatively large range of working temperatures (from −40°C to +85°C).The fundamental working principle of the 12105J470FBTTR is based on the "pyroelectric effect". This involves creating a charge-induced electric field within a material when subjected to a change in temperature. The 12105J470FBTTR uses the pyroelectric effect to form the basis of its function. When the capacitor is subjected to a temperature change, the positive temperature coefficient of barium titanate causes the resistance to increase, thus resulting in a charge-induced electric field to be created. This electric field is then used to store energy for the capacitor.In conclusion, the 12105J470FBTTR is an ideal choice for applications where high frequency performance, stability, and reliability are desired. Its construction is based on the deposition of multiple layers of dielectric material embedded in a ceramic substrate, and its working principle is based on the "pyroelectric effect." This allows the capacitor to be used in a wide range of applications, and offers very low ESR, ESL, and resistance.
