Multilayer ceramic c chip capacitors s Dyn namic DC D Bias s Model for acc curate circuit c s imulatio on • Firrst tool for the dynamic c simulation n of DC bias s characteris stics of MLC CCs • Mo ore accurate e power supply circuit simulation when w used together wiith TDK tec chnical support tools for inductorrs • Mo ore efficientt electronic circuit desig gn July 8, 2014 TDK Corporation has expanded its tecchnical supp port tools fo or MLCCs: T The new DC C Bias Mode el enables designers d to o simulate D DC bias cha aracteristics s of MLCCss, even whe en the DC bias applied to the t MLCCs varies. Tha anks to TDK K’s advance ed electronicc component model, the ccapacitance e in the simu ulation chan nges dynam mically with a changing DC bias vo oltage, an indusstry first*. Until U now, the available simulation libraries only offered m models for one o specificc DC b bias voltage e at a time. The T new DC C Bias Mod del is availab ble in the H HSPICE, LTs spice and PSpiice formats for the mos st commonlyy used circu uit simulator software aand can be down nloaded free e of charge from the T DK Productt Center at product.tdk.com m/en/technic calsupport/tvvcl/general//mlcc.html. With its existing technical support s toolss for MLCC Cs, TDK alre eady providees data tha at enable the ssimulation of o frequency y characterisstics. Becau use the effe ective capaccitance of highperm mittivity MLC CCs (Class 2) changess when a DC C voltage is applied, thee accurate simulation of the ese MLCCss in circuits must also rreflect their behavior when DC biaas voltage is s applied. For tthis reason, TDK’s dynamic electro ronic compo onent model is designeed to simula ate both the frequ uency and DC D bias cha aracteristicss of MLCCs. Used toge ether with thhe DC Supe erimpo osition Mode el, which en nables the ssimulation of o both frequ uency and D DC superim mposition chara acteristics of o TDK indu uctors, the n new MLCC tool enhanc ces the accuuracy of circuit simu ulation for po ower supply y circuits.
