PSMA Capacitor Committee and IEEE PELS Capacitor Workshop:
Everything You Wanted To Know About Capacitors But Were Afraid To Ask
Date: Saturday March 3, 2018
San Antonio, Texas

IEEE PELS and the PSMA Capacitor Committee will hold their first Capacitor Workshop on Saturday, March 3, 2018 -  the day before and in the same venue as APEC 2018 at the Henry Gonzales Convention Center.

Capacitors are far more than just parallel plates. At this workshop industry leaders in capacitor technologies will showcase the details of design, construction, manufacturing, and most importantly applications of capacitors. The topics discussed will be of interest to any of the following:

DESIGNERS of electronic circuits
MANUFACTURERS of electronics and electrical equipment
MANAGERS of engineers, supply chain, purchasing

Workshop attendees can arrive to the meeting room between 7:00 AM to 8:00 AM for a buffet style breakfast, demonstrations, and informal discussions with their colleagues and peers. The demonstrations will also be available during our 2 hour buffet Lunch, and the Networking Session after the workshop. These Demonstrations are intended to be supportive of the Workshop material.


  • Ripple current effects on different capacitor technologies
  • DC Bias behavior of MLCCs
  • Push your filter design to success, comparison between different capacitor technologies
  • How capacitors e.g. MLCCs will be effected from mechanical stress like board flex
  • How self-healing works on film capacitors
  • How to use LTSpice simulations best
  • How to find the proper capacitor in online tools e.g. K-SIM
  • Comparison of capacitor technologies with online platforms e.g. REDEXPERT
  • Special table: How Virtual Reality helps to understand the components behavior? Have you ever ask yourself  how to see the inside of a passive component easily? Let’s dive into it in the virtual world.

The workshop will be divided into 3 primary sections: low voltage DC capacitor applications, high voltage AC & DC capacitor applications, and common capacitor failure modes

The low voltage DC topics will feature a thirty-minute keynote presentation and five twenty minute lecture style presentations concluding with a thirty minute panel Q&A session. The tentative schedule for this session is as follows:

  • 8:30-8:50 Ceramic Capacitors – Low Voltage DC Wilmer Companioni, KEMET Electronics Corporation
  • 8:50-9:10 Difference between traditional and polymer aluminum caps Frank Puhane, Wurth Electronics
  • 9:10-9:30 Recent Development on Supercapacitors Nihal Kularatna, Waikato University New Zealand
  • 9:30-10:00 Panel Discussion – Low Voltage All Panelists

The AC & DC high voltage power topics will follow a similar format to the low voltage DC sessions with the following topics and speakers:

  • 10:20-10:40 High Voltage Academic Input Robert Pilawa
  • 10:40-11:00 Ceramic Capacitors – High Voltage  Wilmer Companioni, KEMET Electronics Corporation
  • 11:00-11:20 Film Capacitors – High Voltage Scott Franco, CDE
  • 11:20-11:40 Aluminum Capacitors – High Voltage Pierre Lohrber, Wurth Electronics
  • 11:40-12:00 Panel Discussion – High Voltage All Panelists

After the high Voltage Panel Discussion a buffet lunch will be available with 2 hours allotted to allow everyone time to eat and visit the demonstrations of their choosing.

Finally there will be a review of failure modes for all capacitors across the various technologies. Again the discussions will be followed by a panel discussion

  • 2:00-2:30 Recent Advances in Embedded Capacitors Robert Grant Spurney, Georgia Institute of Technology
  • 2:30-2:50 Ceramic Capacitors – Failure Modes Wilmer Companioni, KEMET Electronics Corporation
  • 2:50-3:10 Film Capacitors – Failure Modes Scott Franco, CDE
  • 3:10-3:30 Aluminum Capacitors – Failure Modes Sephan Menzel, Wurth Electronics
  • 4:00-4:20 PELS Session: Failure Modes (Theoretical Input)  Huai
  • 4:20-4:50 Panel Discussion – Failure Modes All Panelists

Following the third technical session there will be a networking hour. Wine, beer and hors d’oeuvre will be served from 5:00 to 6:00. There will be additional opportunity to visit with the technology demonstration stations during this session.

At first glance, capacitors may not sound like the most exciting topic, but with the industry experts that will be presenting, everyone from experienced engineers to the eager engineering minds of tomorrow that are just about to graduate will find something useful in this workshop. The registration fee for the workshop is $325 per participant reducing to $225 for PSMA members, IEEE PELS members and students from an accredited university. After February 1, registration fee increases to $375 reduced to $275 for members and students. the Breakfast and lunch will be provided as part of the workshop. Electronic copies of all presentations will be made available to the workshop participants via a password protected website.

NOTE: The discounted registration fee time is almost over. BE SURE TO REGISTER ASAP

*The PSMA Magnetics Committee and IEEE PELS are sponsoring a High Frequency Magnetics Workshop “Power Magnetics @ High Frequency -  Eliminating the Smoke and Mirrors” that will be held concurrently. Each workshop requires a separate registration and attendees will only be able to attend the workshop they have registered for, but the Capacitor and Magnetics Technical Demonstrations will be open to all attendees of both workshops.
