EMI SUPPRESSION
Electromagnetic interference (EMI), the electrical or
magnetic interference that degrades or damages
the integrity of a signal or the components and
functionality of electronic equipment, is the bane of
electronic device designers. Suppressing EMI is a
solution, through an EMI filter or other component.
Here are some products related to this issue:

High-current toroidal inductor design kit
Signal Transformer recently announced its new High Current
Toroidal Inductor (HCTI) Design Kit. This kit provides a varied
selection of toroidal inductors to design engineers who are
looking for solutions to support EMI/RFI filtering and energy
storage in industrial and consumer goods applications. The HCTI
Design Kit features toroidal inductors that have an inductance
range of 10 to 1000 µH, a DC resistance range of 0.005 to
0.3 Ω, and a dc-rated current ranging from 2.4 to 20 A. Signal
Transformer products utilize custom design coil construction
and ferrite material to have high efficiency through reduced
core loss, low magnetic radiation from self-shielding, and high
energy storage with distributed air gaps.

EMI filter for AC voltages up to 277 V
SCHURTER extended its family of EMI filters for 1-phase
systems with its FMAB HV series. The new filter is suitable
for applications requiring AC voltages up to 277 V, such as one
phase of the 3-phase 480/277-V DC Wye system, typically
used for lighting applications in North America. It is also
rated for 400 V DC. Due to its high symmetrical attenuation,
the filter series is particularly suited for devices using
semiconductors, which regulate high outputs. Furthermore,
the compact, fully enclosed housing provides optimized
shielding through a very stable, flush mounting. The FMAB
HV offers a current range from 1 to 20 A at 277 V ac/277 V
dc according to the IEC standard, and 277 V AC and 400 V DC
according to the UL/CSA standard. It has ENEC and cURus
approval. Temperature range is from −40 to 100°C.
