Testing High Capacitance Ceramic Capacitors [White Paper]

Mar 11, 2014
Testing High Capacitance Capacitors White Paper

An ongoing issue we continuously encounter in the electronic industry is the inability to properly measure High Capacitance Multilayer Ceramic Capacitors (MLCC's). The Testing and Measurement Practices of High Capacitance Ceramic Capacitors paper was designed to help outline key issues associated with obtaining accurate readings when performing these measurements.

Get to Know Your Test Equipment

Understanding your testing equipment's capabilities and limitations is key in eliminating delays due to inaccurate readings in ICT (In Circuit Testing) or incoming inspection. This white paper may help facilitate a better understanding of these limitations and offer a simple solution to help resolve any issues that may be encountered.

The Testing and Measurement Practices of High Capacitance Ceramic Capacitors White Paper covers best measurement practices and the behavior of class 2 MLCC's including:

  • Definition and scope of erroneous measurements
  • Effective measurement frequency and voltage
  • Perovskite crystallographic structure of BaTiO₃ (Barium Titanate) and how it changes over temperature
  • Domains and Dipoles and how they affect the dielectric constant and effective capacitance
  • Aging effects of BaTiO₃
  • Hysteresis loops and how it characterizes the ceramic and DF (Dissipation Factor)

Other information found in this paper may be helpful in determining which component(s) are best suited for any specific application. The paper details how the ceramic utilized in the MLCC's utimately affects the behavior of the capacitor and circuit performance when subjected to various environmental factors such as temperature, voltage and time.

If you're interested in learning more about the methodologies and best practices in measuring high capacitance ceramic capacitors, we invite you to download the white paper. We hope the information provided within the white paper will be useful in your engineering or production departments.
