Toroid coil:When there is a current flowing through a wire, it will produce a certain electromagnetic field around this wire, and this electromagnetic field of the wire itself will be inducted in this electromagnetic field range of wires. Magnetic rings and connecting cables constitute an inductor, which is a commonly used anti-interference components in electronic circuits, for high-frequency noise has a good shielding effect. Magnetic rings have different impedance characteristics at different frequencies. The role of the inductor also screening signals, filtering noise, stabilizing current and suppressing electromagnetic wave interference and other important roles.
The use of magnetic ring inductor: widely used: car charger, adapter, energy-saving lamps, anti-theft devices, induction cooker DC-DC lifting voltage power supply module, network communications, communications equipment, audio, computers, televisions PDA Pocket PC, ADSL, ISDN, MP3, VCD, DCD, advanced electronic toys, telephone, Walkman, 4EL backlight drive, remote control toys satellite receivers, fax machines, and other communications and consumer electronics. , and other communications and consumer electronics.
Product Features And Benefits
1
Good high-frequency effect
Above 200KHZ, the conductivity margin is about twice as high as that of ordinary magnetic rings, and the unit current density is greater than that of traditional round copper wires, and the volume size will be smaller under the same situation.
2
Closed magnetic circuit design
Small magnetic leakage, good impedance balance (small leakage inductance, high consistency), low DC resistance, small distribution capacitance, good heat dissipation, good conduction radiation effect, ideal EMI effect.
3
Advanced fully automated equipment
Single layer neatly arranged winding, no cross overlap, enhance the coil to the warm time over the pressure resistance. Stable performance, high insulation strength, can extend the life of the power supply.
4
With fixed base
The chassis can completely isolate the coil from the PCB board and increase the insulation performance Standard chassis pin size is fixed Easy and convenient insertion operation saves time and improves the production efficiency.
Types Of Coils We Make
1 Single Sided Coil
Single-sided coils are made of insulated wire wound turn by turn on a paper tube or glued wood powder frame such as a crystal triode tape recorder medium wave radio antenna coil.
2、Beehive type coil
If the coil inductance of the coil, the plan view is not parallel to the rotation surface, but only cross into a certain perspective, this type of coil is called a honeycomb coil. And its rotation week, the frequency of transmission line back and forth bending, often called the folding level. The advantages of the honeycomb winding method are small size, small distributed capacitance, and large inductance. The larger the bend, the smaller the distributed capacitance.
3、Ferrite core and iron powder core coil
The inductance size of the coil is related to the presence or absence of a transformer backbone. Inserting a ferrite core into an empty core coil can increase the inductance and enhance the quality factor of the coil.
4、Copper core coil
Copper core coils are more commonly used in the field of low frequency therapeutic devices, using rotating the copper core in the coil to change the inductance, this type of adjustment is more convenient and durable.
5, color code inductors
Color-coded inductors are inductors with a fixed inductance, and their inductance is marked with a color disk like resistors.
6、Resistor coil (choke coil)
The coils that limit the AC current are called choke coils and are divided into high frequency choke coils and low frequency choke coils.
7. Deflection coil
Deflection coil is the load of the output stage of the power supply circuit of the TV scanner, the provisions of the deflection coil: high offset sensitivity, the electromagnetic field is proportional to the high Q bias, small size, inexpensive.

Why do inductor coils get hot?
Inductor coil heat is due to the coil resistance is very low, 220V voltage plus will produce a lot of current, the current will be very hot, you can try to increase the voltage frequency, frequency increases, the inductive resistance increases, the current is small.
What are the causes of damage to inductor coils?
(1) The engine does not operate, and the ignition switch is left on for a long period of time, destroying the coil insulation in the coil due to the thermal effect of the current.
(2) Engine overheating, coil insulation varnish is baked and fails.
(3) Spark plug electrode gap is too large, increasing the coil load, so that the high-voltage coil breakdown, resulting in a short circuit or disconnection.
(4) The high voltage line is disconnected, so that the high voltage generated by the high voltage can not be passed, easy to cause the high voltage coil is punctured. At this time the engine is not easy to start, should check whether the high voltage line is disconnected.
What should be kept in mind when selecting an inductor coil?
Inspection of Inductive Coils When selecting and using inductive coils, the first thing to think about is the inspection and measurement of the coils, and then go on to judge the quality of the coils, good or bad, and the merits and demerits of the coils.
Winding coil of attention coil in the actual use of the process, there are a considerable number of varieties of inductive coil is non-standard, are targeted according to the need for winding.
Measures taken to improve the Q value of coils Quality factor Q is an important parameter reflecting the quality of coils, and improving the Q value of coils can be said to be one of the key points to be paid attention to in winding coils.
