RayMing Technology: much more than a PCB maker!
RayMing Technology is an Electronics Manufacturing Service
(EMS) provider, specifically, offering PCB manufacturing and PCB assembly. EMS is a specialised form of Contract Manufacturing (CM).
EMS companies allow equipment manufacturers to improve their
efficiency, allowing them to focus more on Research and Development (R&D). RayMing Technology has more than 10 years of experience providing EMS services. EMS services are not only used
to make consumer products, but also medical products, industrial
products as well as products for defence, aerospace and telecommunications.

Johanson Dielectrics Advanced
Motor EMI Filters
Strict electromagnetic compatibility (EMC) requirements and noisier electronic environments are
threatening to increase the cost
of filtering required for brushed
DC motors. These filters must
reject all forms of noise and also
handle high DC currents, without being costly. Johanson Dielectrics advanced
monolithic EMI filters meet these requirements.
Traditional common-mode filtering approaches include lowpass filters comprised of capacitors and/or inductors that attenuate signals above the cutoff frequency. The traditional options are
two-capacitor differential filters, three-capacitor filters (one X-cap
and two Y-caps), feed-through filters, common-mode chokes, LC
filters, or combinations of these.
These days, the lower-cost options like two-capacitor or threecapacitor filters can no longer meet all EMC requirements. Other
solutions like common-mode chokes offer good rejection over a
wide frequency range, but are expensive when they must carry
several amps.
Monolithic EMI filters provide significantly more RFI suppression than a common-mode choke in a much smaller package,
and they are not affected by the direct current requirement, because they connect between the lines and ground.
These filters from Johanson Dielectrics combine two balanced
shunt capacitors in a single package, with mutual inductance
cancellation and a shielding effect.
The key to their performance is the very low inductance and
matched impedances. Monolithic EMI filters can be effective
from 50kHz to 6GHz, filtering both common-mode and differential-mode noise.
Sometimes EMI filters can interfere with PWM-based motor
control, so the right filter must be chosen for the job. Johanson Dielectrics provides an on-line tool that simplifies filter choice. They
