What is a Filter?

Filters are used to suppress electromagnetic interference (EMI) on signal lines, power lines or in electronic circuits. This interference may be caused by the device itself or by other equipment.

Types of Filters

There are several different kinds of filters at Future Electronics. We stock many of the most common types categorized by several parameters including case size / dimension, impedance, rated current, maximum DC resistance, packaging type, and other attributes specific to each type of filter. Our parametric filters will allow you to refine your search results according to the required specifications.

Filters from Future Electronics

Future Electronics has a wide range of filters from several manufacturers. Once you decide if you need Common Mode Chokes, EMI Filters or Ferrite Beads, you will be able to choose from their technical attributes and your search results will be narrowed to match your specific filter application needs.

We deal with several manufacturers such as Epcos, Murata, NIC Components, Panasonic Industrial Devices and TDK, among others. You can easily refine your filter product search results by clicking your preferred filter brand from the list of manufacturers below.

Applications for Filters:

Common Mode Chokes can be used in the suppression of radiation noise in electronic devices, in countering common mode noise affecting signals in high-speed lines and in panel link lines for LCD panels.

EMI filter applications include secondary power supply lines for digital audio / video and communications equipment, computer motherboards, and computer peripherals including hard disk drives, USB hubs, printers and DVD ROMs.

As for ferrite beads, they can be found in applications requiring the removal of power line noises in PCs, digital photo frames, mobile phones, TV tuners, DVDs, audio players and game machines.

Choosing the Right Filter:

With the FutureElectronics.com parametric search, when looking for the right filters, you can filter the results by category. We carry the following categories of filters:

  • Common Mode Chokes
  • EMI Filters
  • Ferrite Beads

Once you choose the filter category, you can narrow them down by various attributes: by impedance, case size / dimension, maximum DC resistance and rated current, to name a few. You will be able to find the right EMI Filters, Common Mode Chokes or Ferrite Beads by using these filters.

Filters in Production Ready Packaging or R&D Quantities

If the quantity of filters you require is less than a full reel, we offer to our customers several of our filters in tray, tube or individual quantities that will help you avoid unneeded surplus.

Future Electronics also offers its clients a unique bonded inventory program designed to eliminate potential problems that may arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
