Working Principle

Thin Film Capacitors, such as the 06031K3R3BAWTR, work on the principle of electric field formation between two conducting plates with an insulating layer in between them. In other words, the electric field between two conducting plates is stored as an electrical charge in the dielectric medium (insulator). The stored electric field is related to the dielectric constant of the insulating medium, which determines the capacitance of the component.

Additionally, a higher temperature can increase the capacitance of the capacitor due to the increased dielectric constant of the dielectric. As a consequence, it is recommended to consider temperature coefficient compensation when selecting a Thin Film Capacitor for an application.

On the other hand, the residual inductance of the component is related to the physical shape and geometry of the component. This inductance is determined by the number of layers of dielectric and their thickness, as well as the distance between two conducting plates. A thinner dielectric layer increases the self-resonance frequency and decreases residual inductance.

Conclusion

The 06031K3R3BAWTR is a reliable, cost effective and high performing Thin Film Capacitor. Its small size, wide capacitance range and low ESR and ESL characteristics make it ideal for many different application fields. Its working principle, based on electric field formation between two conducting plates with an insulating layer in between, coupled with the temperature coefficient compensation and the physically shaped dielectric layers make the 06031K3R3BAWTR a reliable and cost effective component.
