Taiyo Yuden provide various component libraries for microwave circuit, PI and SI simulators. The recent release add long time wished temperature/DC Bias Models on MLCC capacitors for HSPICE and Spectre simulations.
Temperature/DC Bias Model Reflect the characteristics of the ambient temperature and the applied DC bias while standard model shows simulation values at 25℃ and DC 0V/A.
MLCC class II high electric field dielectrics may change its parameters with temperature and DC BIAS, thus it is important to use high fidelity MLCC models during simulation process to achieve simulations closer to the real operating conditions.
