Once again, we are proud to announce a new Technical Sales partnership!
NexTek and Rankin Components have formed a relationship in order to provide local Technical Sales and Support for customers in the Northern California region. Rankin is the most recent of a long line of new relationships with highly skilled local manufacturers’ representatives, and we are extremely excited to have them on-board!
High Current EMI Filters are commonly used on high power feed lines within MRI Machines and high-power Medical Lasers, in order to prevent any electronic interference issues and provide full Electromagnetic Compliance to common Medical Equipment regulations.
EMI Filters can be required on the Noise Source or the potential Noise Victim, and sometimes are installed on a certain line for both reasons! A filter installed on a properly shielded barrier will provide fully bi-directional protection.
What Types Of Medical Equipment?
In terms of devices that are likely to have a high-current connection and EMC requirements…MRI Machines and Medical Lasers are the most common types that might require a high current filter.
What Makes These EMI Filters Effective For the Application?
Our HPR Series filters are the Most Compact units available for their current ratings, and combined with Excellent Filtering Performance and an especially Rugged Design they are ideally suited for any high-current DC or AC filtering application. Medical equipment is subject to some of the most stringent EMC requirements of any industry, mostly because in most medical facilities there is a lot of equipment operating in close proximity with each other. Combine the crowded environment with the fact that people’s lives may be on the line when this equipment is being used, and you have the perfect explanation for the tough EMC requirements.
We are happy to announce the recent release of a brand-new two-page bulletin and brochure, featuring our range of compact high-performance arrestors. Whether you are working on a new design, or trying to retrofit something onto an existing one…these ultra-small options are ideal for any application where size is a critical design factor.
Instead of trying to add some (likely inadequate) transient protection on-board, or having to go all the way to a traditional external arrestor mounted somewhere on the cable run…It is now possible to integrate world-class protection against Lightning, Static (ESD) or High-Speed EMP into a bulkhead connector that will easily replace most existing I/O feedthrus!
With the wide array of connector options and frequency ranges available, you should be able to find a solution for any application. Learn more and download the new Product Bulletin by following the jump below;
You Might Not Know; Just as our line of Power Filters are used to provide EMC compliance for a wide variety of military and government applications, our line of Surge Arrestors for coaxial RF lines are also in-use on an wide range of systems worldwide!
Whether they are installed on a Permanent Installation or a Land Vehicle, Ship, or Airborne Vehicle… Our surge arrestors provide the type of rugged performance and long lifetime that any Military or Government user demands. Solutions range from standard off-the-shelf units all the way to fully-custom solutions developed to meet a complex or special set of requirements.
We can provide protection against any threat type, including;
With the proliferation and continued growth of the use of Radios and Radio-based technology (sensors like radar, communications, even electronic warfare [EW]) across all military equipment and systems, there are a growing number of requirements for Lightning and Surge protection to ensure that mission-critical equipment and capabilities remain up and working properly at all times!
In fact, NexTek was formed as an EMC engineering consultant outfit, and our first contracts ever were in the Military world. With this type of experience and pedigree, you can be confident that your NexTek arrestor will provide protection, performance, and trouble-free operation…whether you are using it in a Mil/Gov application or not!
Today’s Featured Application and Did You Know? topic covers NexTek HPR series power filters and the fact that they are used in radar power supply systems around the world. We have EMI filters installed in fixed ground, land and sea mobile, and also airborne radar systems to help enable compliance with applicable EMI and RFI requirements at the system-level.
See below for an example of a ground mobile radar system where HPR series filters could be used, usually mounted within the Power Supply sub-system.
Unique Features that make HPR Series Feedthrough Power Filters ideally suited to these applications;
Robust and Rugged Design – High Performance in any Environment
Compact Size and Form Factor – Save the Maximum Amount of Space and Weight
Filtering Performance to 1GHz+ – Exceptional High Frequency Filtering Performance
High Reliability Units Available – Burnt-In Units for Maximum Reliability
No matter what type of radar system is being designed, NexTek HPR Series EMI and RFI filter solutions for power lines are uniquely suited for the challenge!

The Science Behind Lightning and Its Awesome Power
Lightning strikes can be such awe-inspiring natural events, with the power to light up the night sky, travel 10s of miles, and enough energy to start fires and melt metal in their path! Learn more about the science behind Thunderstorms and the Lightning they produce by following the link to our previous post, where you can find the link to wired.com’s original article.
Watch Ultra-Slow Motion Video of Lightning Bolts – They Reveal Lightning’s Secrets!
Lightning Strikes form and disappear so quickly, (they are over within 200 microseconds, or <.0002 Seconds!) that it is difficult for the human eye and brain to process as anything other than a rapid single or multiple flash. However, the formation of a lightning bolt is actually an intricate and multi-step process that is much more complex than we have believed for most of human history. With the advent of ultra-slow motion video cameras, lightning strikes can be captured during their formation stages all the way through their connection and peak current flow (the brightest flash which results in Thunder.)
For many applications where there are extreme environmental requirements such as Extreme Temperature Ranges, Shock & Vibration, and others are present…A filter’s ratings and performance across every type of application are an important way to vet any component for use in harsh environments
Some filters have extremely limited Temperature Range Ratings, especially in terms of Maximum Temperature
Some filters have a limited ability to withstand Shock and Vibration, and therefore would not be suitable for any type of mobile application.
