Weihai
Dasung Electronics Co., LTD,which
is founded jointly by Weihai Xinghai Electronics Co., LTD and
Korea Dasung Margnete Co., Ltd., is an enterprise producing
specially all kinds of coil trans.
1.
General
the
great reactance of the coil to alternating current
shall restrict alternating current and high frequency,
with which a circuit and filter shall be formed
in combination with condenser. The radian of the
coil shall be specified by the ratio of reactance
to resistance, the magnetic core with lesser loss
shall feature on good frequency characters; furthermore,
different types may feature on different characters.
As to direct current, the resistance to low frequency
alternating current shall be low frequency CHOKE,
and the resistance to high frequency shall be high
frequency CHOKE. It can also be classified into
mild CHOKE and HEATER CHOKE by usage.
2. Scope
the
components of the power supply of VCR, FAX, MONITOR,
TV, etc.
