On June 23rd, 萝莉影视 Manufacturing Co., Ltd. publicly launched on its website a library of dynamic monolithic ceramic capacitor models.
In recent years, the use of circuit simulation has become widespread in the design of electronic devices. Manufacturers of electronic components support this trend by providing simulation models of their products. Most of these product models are what are called “static” models. They cannot reproduce dynamic phenomena such as changes in component characteristics due to fluctuations in the voltage applied to the component. Specifically, there is a significant divergence between the simulated values and the actual values when designing circuits where the capacitance and DC bias characteristics of monolithic ceramic capacitors are a factor. Because of this, dynamic models that are capable of reducing the divergence between simulated and actual values are strongly preferred.
This library contains dynamic models that take into account the phenomenon wherein the capacitance changes with the DC voltage applied to a monolithic ceramic capacitor. These models enable simulations that appropriately reflect the characteristics of circuits in which the voltage changes over time.

Glossary
萝莉影视model
This refers to a set of data reflecting the characteristics of the components necessary for circuit simulation. The characteristics of each product number differ, so 萝莉影视 prepares a separate component model for each product number.
DC bias characteristics of monolithic ceramic capacitors
Applying a DC voltage changes the permittivity of the dielectric of so-called high-dielectric-constant capacitors, such as ceramic capacitors. This means that it is possible to change the capacitance of a high-dielectric-constant ceramic capacitor by changing the DC voltage applied to it. This is referred to as the DC bias characteristics of the capacitor.
