Thin Film Capacitors

Thin film capacitors are composed of thin film of metal oxide compound that is deposited on a ceramic substrate. They offer improved electrical properties over the more common wire-wound or wet-film capacitors, with lower equivalent series resistance (ESR), higher stability and better temperature behaviour. And they are suitable for a wide range of applications, including high-density packaging, RF communication and automotive electronics.

04023J0R5PBWTR/500 Application Field and Working Principle

The 4023J0R5PBWTR/500 thin film capacitors are specially used under the frequency range of 0.05-4GHz for different representative application such as sensor array, operation amplifiers, broadband frequency generator, bypass capacitance, and micro-wave tubes. Moreover, it is also suitable for application on high-impedance micro-circuit controlled or power line, or biased on lithography. With frequency of 1 GHz below, it can meet the requirement of decoupling input and output signals in oscillators, phase locked loop and mixers.

Basically, the working parameter of the 04023J0R5PBWTR/500 is based on the capacitor’s ability to provide a low electrical impedance between the two plates, by the dielectric material between them. With the presence of an electric field, a separation of electrical charge will occur between the two plates creating two oppositely charged polarity. This polarization of the flat plates results in the reduction of the size of the gap between them and thus, increases the distance of electric charge path.

To measure the capacitance of the 04023J0R5PBWTR/500 thin film capacitor, an alternating current source needs to be connected between the two plate. In this case, the potential difference between the plates, such as a voltage, will change linearly with time, resulting in a “capacitance”. The measured capacitance is the value that the capacitor is able to store the charge, and it can have a range from 0.5pF to 500pF according to the different range of external electrical field.

Other than that, the 04023J0R5PBWTR/500 capacitor is also featured with a low differences between values at 1, 5 and 10V, very low parasitic capacitance, equal capacitance of X and Y-axis, and stable capacitance, self-resonance frequency and low dissipation factor with bias voltage, series inductance and parallel resonance frequency which all make it ideal for ac/dc filtering, RF couplings and RF bypass capacitor for high frequency circuits.

In conclusion, the 04023J0R5PBWTR/500 thin film capacitor offers many features and characteristics suitable for many applications. It is long term reliable, and it is highly reliable when exposed to harsh environmental conditions, including moisture and vibration. With its excellent electrical stability, the 04023J0R5PBWTR/500 offers great protection against temperature cycling and shocks, as well as operating temperature up to +85° C.
