HIGH-FREQUENCY
TRANSFORMER |
|
Brief Introduction &
Directions
The high-frequency transformer
is a new kind of main transforming
power component which adopts
good-quality and high-frequency
Fe-oxidized material as its
magnetic core. It provides high
efficiency, small volume, wide
scope of stablzing voltage and
good quality in electric isolation.
It is widely used in many fields
such as efficient main, audio-frequency
transforming, microwave communication
of CRT line scanning drive etc.
At present it has been commonly
used in various kinds of products
such as CTV, monitor, DVD, and
computer, illumination, etc.
FEATURES
1. It adopts the magnetic core
of low loss, high magnetic flux
density, and it has little over-temperature.
2. Switch frequency:20KHz-500KHz.
3. Style of working circuit:single-pole
positive stimulating type,single-pole
negative stimulating type,push-pull
type and bridge type.
4. Heat resistance class:B
class 5.The safe parameter is
in accordance with the standards
of UL,VDE,CE,IEC,etc.
NOTICE
1. The switch main transformer
should be designed and selected
according to the parameters
of working circuit type,output
power,working frequency,etc.
2. The signal transformer should
be selected according to the
parameters of signal frequency,standing
wave demand,insertion loss and
impedance,etc.
3. The construction type of
high-frequency transformer should
be selected in accordance with
parameter demands and feasible
economy.Usually EE,EER(EC),EI,EP
and PQ types are used for the
construction.
4. The out-line of transformer
can be distributed according
to the customer's PCB board.When
using the transformer,Customers
must make sure that it has been
correctly connected.Any worng
connection could damage the
whole machine,or the machine
would not work properly.

DEGAUSSING-COIL
|
|
|
Brief Introduction &
Directions
Degaussing coil is a alternative
magnetic field,which is caused
by alternative current in
the geometric center of coil
as per magnetic induction
principle,this alternative
magnetic field can eliminate
magnet of the negative pole
located in geometric center
of this alternative magnetic
field,so that can improve
CRT color purity,At present,this
type is widely used in various
kinds of CTV,MONITOR,etc.
FEATURES
1. Customers can order external
size parameter of degaussing
coil and connect harness.
2. Products can be taken
form according to customs'
demands.
3. Products are in accordance
with safe standards such as
UL,VDE,IEC,etc.
NOTICE
1. When customers order a
degaussing coil,they should
be well aware of parameters
such as coil size,connect
harness,DCR,number of tape
layers.
2. To ensure the degaussing
effect,customers should be
sure of enough AT value.
3. Only when a degaussing
coil matching with the proper
heat-sensitive resistance,it
can get the best degaussing
effect.
4. Avoid damaging isolation
layer to ensure product's
safe parameter,while using
it.

POWER WAVE FILTER、INDUCTORS |
|
|
Brief introduction &
Directions
The power wave filter is a
new one that adopts good-quality,high-frequency
Fe-oxidized material as magnetic
core and works as per zero
magnetic flux principle.It
has fine characteristics of
EMI and EMC,and it is also
widely used in various kinds
of product such as CTV,MONITOR,computers,air-conditioning
equipment,OA equipment and
other home appliances. The
sensor adopts high-frequency
Fe-oxidized or Fe-Ni alloy
as magnetic core.It is mainly
used in filtering wave,storing
energy,choke and CRT field
scanning linearization.This
component is widely used as
one of the three basic units
of electric circuit.
FEATURES
Power
wave filter:
It can effectively suppress
common mode noise.It has wide
frequency scope and high efficiency.It
is in accordance with EMI
standards such as FCC,VDE
etc,and safe standards such
as UL,VDE,IEC,etc.It also
has the features of small
volume and lightweight.
Sensor:
small volume,lightweight,wide
working frequency scope,low
.loss,little over-temperature.
NOTICE
1. When customers order a
power wave filter and sensor,they
should be well aware of the
parameter demands such as
volume of the products,current
and inductance etc.Regarding
line inductance,customers
also should be aware of the
direct current overlap magnetization
curve.
2. When a wave filter works
under the condition of approaching
zero magnetic,the inductance
of the two coils should be
equal.Therefore,while using
it ,do not adjust it at option.
3. Wave filters are usually
divided into the following
types according to magnetic
core construction:UF(UU)type,ESQ
type,RING type etc.
4. Sensors are usually divided
into the following types according
to magnetic core construction:drum
type,ring type,rod type,etc.

INVERTER TRANS |
TFL LCD Inverter,leading the
technology of Display,is switching
D.C. into A.C. fot the device
of Back Lighting to support
PC and Monitor in Lighting
Technology. It's the key part
of Lighting.

CRT
SOCKET
|
CRT SOCKET is
kind of touching equipment
that connects CRT with electric
circuits. Especially after
CRT gets high transformer
from FBT (Flyback Transformer)
to provide to itself, it can
bear high transformer. After
the excessive transformer
that appears in inner electric
circuits, high magnetic field
and electric field meet the
terra, it can protect the
inner equipment. CRT includes
CDT (Colour Data Tube) and
CPT (Colour Picture Tube)
CDT is used in Monitor, and
CPT is used in TV.

MATCHING TRANS
|
The main function
of M/Trans is to connect Antenna
with TV. Balun Trans of M/Trans
only alters resistance from
300Ω to 75Ω ,it's the device
from Antenna(300Ω) to TV(75Ω).
