DC
Astrodyne TDI offers the solutions needed to combat issues concerning both EMI and RFI, safely and effectively. We offer an array of DC EMI/RFI/EMC Filters to meet the needs of various industries and applications. At Astrodyne TDI, we offer DC EMI Filters that can attenuate EMI with the highest performance possible. We offer models designed for both high performance and high current. High-performance filters are specifically designed to produce the best filter quality, while high-current models require more phases to reduce the effects of EMI successfully.

WHAT ARE DC EMI FILTERS?
Most types of electrical and electronic devices, including Power Supplies, emit electrical noise. When two devices are close to each other, the electrical noise of one can interfere with the operation of another — known as Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI). An EMI filter is used to suppress the electrical noise that stems from electric currents in the device's wiring, reducing EMI for a clearer signal.
Due to the fact that most Power Supplies operate using DC voltages, DC EMI Filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents. This arrangement allows for the full functionality of the device while diverting unnecessary noise.
DC EMI Line Filters help Power Supplies meet EMI regulations. EMI filters themselves must meet stringent safety standards to minimize the device's risk of electric shock and fire hazards. At Astrodyne TDI, our DC power line filters are tested in-house to conform to worldwide safety standards. Each filter carries U.S. (UL), European (IEC/VDE/Semko), and Canadian (cUL/CSA) agency approvals.
USES OF DC POWER LINE FILTERS
Although AC/DC Power Supplies feature their own internal EMI Filters, sometimes, the systems they power generate more electrical noise than the internal filter can handle on its own. Separate Power Filters are useful in these situations to bring the noise down to acceptable levels.
Use DC EMI power line filters to combat interference in applications such as:
- Modems
- Network Routing Equipment
- Servers
- Ethernet Hubs
- Base Stations
- Power Supplies
