DC Superimposition model / DC bias model< Abstract of the DC superimposition model and the DC bias model >Power-use inductors have a property called “DC superimposition property” which means the changeof the inductance by the DC current applied to the inductors. Ceramic capacitors have a propertycalled “DC bias property” which means the change of capacitance by the DC voltage applied to thecapacitors. Those properties can be considered in the simulation from the library version 2015.05.The components in which those models are used have “D” mark on their icon.

About the property tolerance model < Abstract of the property tolerance model >The property tolerance model is a new type of simulation model that includes electrical tolerancedata of products. The property of actual electric parts have unevenness within tolerance of theproduct due to unevenness of manufacturing. Simulated result of this model varies at random withinthe tolerance of the product. Hence, the model can be used in worst case analysis of your circuits.

How to use the property tolerance model (1)< Putting and setting the component >The property tolerance model is provided for temperature compensation type multilayer ceramiccapacitors and inductors for RF circuits. (The component that has “T” mark in the icon is theproperty tolerance model.) Click the component icon of the property tolerance model, and put asymbol on the schematic window. Double-click the symbol, then TDK part No. and use/no-use oftolerance data can be selected in the setting window. If ToleranceData=Disable, the model worksjust same as the conventional model that shows typical property of product.
