MLCC直流偏压特性测试参数研究

摘要

In order to evaluate DC bias characteristics of multilayer ceramic capacitors(MLCCs) with high permittivity dielectrics, tests on DC bias characteristics of X7R MLCCs were performed using E4980A precision LCR meter. And then influence of loading time of DC bias and auto level control function on DC bias characteristics of samples was studied. The results show that those test parameters can influence test results.%为了评估采用高介电常数陶瓷作介质的多层陶瓷电容器（MLCC）的直流偏压特性，使用E4980A精密LCR表对X7R特性MLCC进行直流偏压特性测试，研究了直流偏压加载时间和自动电平控制功能对样品直流偏压特性的影响，结果发现这些测试参数都会影响测试结果。
