Coming Soon To Our Lineup… A High Current Pi-Filter (C-L-C) for Maximum EMI Suppression

We have been designing and building feedthrough EMI Filters for high current (30Amps and above) AC and DC applications for nearly 30 years now. There have been multiple design iterations and some important innovations over this time period, but our filter products have been limited to C-Type filters only.
However, this is all about to change! Coming soon, we have a brand-new Pi Filter design for high-current applications. C-L-C Circuit Design means a sharper Insertion Loss curve once the filter turns on, and higher maximum filtering figures approaching 100dB of Loss.


A Small Preview of Design Features:

  • C-L-C aka Pi Filter Configuration
  • Extremely Compact Package for 180Amperes of Thru-Current
  • Available in a Wide Range of AC and DC Voltage Ratings
  • Optional Transient Suppression Available


Expect to learn more over the coming months as Datasheets, Product Pages, and more information will be available soon!


Featured Threat Type – Lightning Protection for Radio and Communication Lines

Although probably our best-known type of solution, we wanted to take the opportunity to start off 2017 by highlighting Lightning Protection for coaxial RF applications.  Fundamentally, the purpose of these devices is to provide high-performance Lightning & Surge Protection for Radio and Electronic Systems and their Users.  This can be as simple as protecting a radio itself, or as complex as providing protection to the entire platform or system the protection is being installed upon.


Simplified Diagram Showing Typical Wireless Communications Installation – Potential Arrestor Placement Areas are A, B, and C.

You can see the common areas where protection is installed called out as A, B, and C in the diagram above.  This is an over-simplification and does not exactly represent most actual installations, but it does a good job representing the various ways and reasons that a coaxial cable can be installed outside and therefore represent a potential ingress path for Transient Lightning Energy.


Wireless Installation - Building Rooftop

Lightning damage is a leading cause of radio damage in many locations and systems around the world.  Anywhere a coaxial cable or radio antenna is run outside in an exposed location, there is a potential need for an arrestor/protector on the line as well.


While we do specialize in coaxial connectorized solutions where RF Energy must be passed during normal usage, we also do have many years of experience in designing and consulting on all sorts of Surge Protection devices… From Lightning Arrestors for AC, DC, or Serial/Comms lines, to providing multi-faceted protection that is as effective against Static/ESD and HEMP/NEMP energy as it is against standard Lightning transients.

Product Bulletin – Integrate RF Surge and Lightning Protection Without Paying a Size or Weight Penalty!

The Neverending Quest For Size Reduction

As with most technologies, RF and Wireless system design is an ever-changing and shifting world.  As certain technologies or RF bands become popular, others fade away.

However, the one ever-present force on the industry is the steady, but relentless, push towards smaller size and better integration over time.

Lightning/Surge Protection at the PCB Level?

Here at NexTek we understand the desire to bring things into the box, or even all the way onto the Radio PCB… However, we also know that Lightning Transients contain too much energy to deal with safely at the PCB Level… Trace widths, ground place areas, and the components themselves all become limiting factors that will prevent complete and effective protection.

Given this reality, the last place where it is reasonable and safe to protect against Lightning or other Surge events is at the radio’s box or chassis level.  By replacing the normal I/O connector with a protected version, designer can ensure that they have high-performance protection without paying any significant size or weight penalty.  As long as the radio’s chassis is grounded well, the bulk of the Transient Energy will be drained safely to ground before entering the box and/or the PCB itself.

It may still be advisable to install some simple protection on the PCB, but only for final clean-up…Something like a small Protection Diode coupled with a DC Blocking Capacitor (if possible for your application) would provide plenty of protection against any residual energy that gets past the Protected I/O Connector.

Maximum Protection in the Minimum Amount of Space

Below, you can see an array of our Ultra-Compact protection options…  They all include high-performance lightning protection, and are available in a wide variety of connector configurations on both the Input and Output side.compact-arrestors

Outside Connector Options – Type N, TNC, SMA

Inside Connector Options – SMA, MMCX, RG188, RG316, and more!

Did You Know? – NexTek EMI Filters Are Used In Medical Equipment to Prevent Unwanted Electrical Interference

Where Are These Filters Used?

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 Diagram - CC0

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.

MRI - CC0

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.
