EMI Filter Solutions
With decades of experience in the design and manufacture of Power Supplies, Astrodyne TDI has been researching, refining, developing and providing EMI filters for Commercial, Industrial, Medical and Military applications for more than 50 years. In that time, we’ve earned our reputation as an industry leader that helps companies succeed and operate within applicable electronic and energy standards.
Why Use an EMI/RFI Filter?
In the broadest terms, EMI and RFI amount to interferences of an electrical or magnetic nature that can degrade how well a piece of electronic equipment performs or the quality of the signal it receives — which is responsible for its nickname “noise.”
From narrowband man-made EMI, such as the hum often heard from power lines, to natural broadband interference like solar flares and lightning strikes, our world is filled with electromagnetic interferences that can range from random and sporadic to continuous and constant.
In addition to external forms of EMI, there are a number of ways electronic devices can produce their own EMI through activities such as generating impedance, or an opposition to the current flowing through a given device. Besides the electronic noise present on signal and power lines, a good deal of high-frequency noise is produced by devices such as electronic appliances, controls, motors, inverters, power supplies and microprocessors.
Sensitive devices, such as computers, medical equipment and military equipment, need to function free of interference for purposes that are often of a mission-critical nature.
Off-the-Shelf Versus Custom EMI Filters
Depending on your product and business sector, you might need a cost-effective off-the-shelf EMI Filter for an application you manufacture. In regards to advanced Aerospace, Military and Medical devices, there might not be a substitute for the performance and ruggedness of a custom EMI filter.
Fortunately, at Astrodyne TDI, our wide selection of quality off-the-shelf EMI filters plus our in-house engineering and design expertise mean that we can always supply you with an EMI solution that seamlessly fits your equipment’s requirements as well as the industry standards. Our EMI Filter solutions range from a collection of small Single Phase components up to Industrial Grade 2,500A/690V Three-Phase Filters. Additionally, the majority of our standard inventory carries International Agency Approvals from recognized organizations such as Underwriters Laboratories (UL), Canadian Standards Association (CSA) and Conformité Européenne (CE).
