EMC Filters Comparison Part II: π and T Filters

In this article the performance of the π and T filters is evaluated and compared to that of the CL and LC filters.

Let’s Talk About Why Filters Fail

This article looks at some of the reasons why the filters you may think will work often do not when they’re put into real circuits. So… let’s talk about why filters fail.

What Every Electronics Engineer Needs to Know About: Filters

There are many different types of filters used in electronics. These filter types include...

S-parameters and EMI Filter Response

S-parameters are very useful to evaluate, understand, and optimize the response of your filters. If you are unfamiliar with this typical tool for RF engineers, this column is for you.

A Basic Overview of RF/EMI Filters and Filtered Connectors

When considering filters and filtered connectors to help eliminate noise issues in a system, determining the best EMI solution is based on the mechanical configuration of that system.

Facility Power Filters: Symmetric vs. Asymmetric Performance

1309 F3 coverAsymmetric filter designs are gaining popularity in industry because of their lower cost and size, however, although this design is successful in eliminating common mode signal issues this paper will show that for certain applications such as TEMPEST these filters offer little to no protection. Symmetric filters, although physically larger and more costly due to the use of more components, provide better filtering in these applications.

High Current Filtering Technology – The HPR Series

NexTek's HPR series of extremely high current filters is ruggedly designed to operate at current levels up to 400 amperes and voltages up to 500 Vdc. A large range of available capacitance provides significant insertion loss at frequencies as low as 1 KHz, and provides over 60 db insertion loss to above 1 GHz.
