IEEE EMC Phoenix

In Memory of Terry Donohoe
We are sad to report the death of our friend and colleague, Terry Donohoe. He crashed while flying his experimental aircraft near Phoenix, apparently as a result of controls failure.

Here is a link to the news media:

We will miss his outspoken humor and are in his debt for re-launching the Phoenix EMC Chapter back in the early 2000's.

Terry Donohoe, Past Chairman of the Phoenix EMC Chapter

Welcome to the IEEE EMC-Phoenix Web Page. We are the Phoenix Chapter of the IEEE Electromagnetic Compatibility (EMC) Society. We are dedicated to providing quality EMC instruction, establishing a network of EMC professionals, and assisting one another in our careers in EMC design and test.

The IEEE EMC Phoenix Chapter met January 19th, 2012 at Garcia’s Mexican Restaurant in the Embassy Suites Hotel at Rural Road and I-60 in Tempe, AZ. The meeting began with the customary social hour starting at 5:30 pm, with dinner at 6:00. At 6:15, our chapter Chair Harry Gaul called the meeting to order.

Before the regular meeting Daryl Gerke of Kimmel Gerke Associates, Ltd. took a couple of minutes to pay homage to the memory of Terry Donohoe, one of our members and former Chairman of the Chapter. He sadly perished in a crash while piloting his experimental aircraft in December. Terry will always be remembered with gratitude for his efforts in re-launching of the Phoenix EMC Chapter in the early 2000’s. He will be sorely missed as a friend and colleague.

Our speaker for the evening was David Stanis, Retired General Manager Filter Division of WEMS Electronics. His talk addressed the various types of industry wide custom EMI filters both single circuit components and multi-circuit filter assemblies. Mr. Stanis started by presenting the basic types of filters, their structure and recommended application. The modes of propagation of EMC Noise (Radiated and Conducted) Susceptibility issues they pose and filter type selection to address them were discussed.

The difficult task of properly identifying the EMC issue and correct selection of a suitable filter to address it was discussed next. Mr. Stanis emphasized the need to work closely with the filter manufacturer to tap into their extensive knowledge and expertise especially when it comes to size and derating. Involving a knowledgeable team in the design effort at early stages can help identify and solve issues faster and at lower cost. Various aspects of filter specification were presented: topology, voltage and frequency, operating temperature and humidity, housing type and mounting requirements, space constraints, hermetic sealing, etc. The presentation concluded with a discussion of Electrical and Environmental Test methods, Quality Inspection and Data reporting considerations. The meeting was called to a close at about 8:30 pm. Our thanks to Mr. Stanis and to all who attended!
