The winding inductance _ inductance coil can be used in what goods

1 SMD coil uses: widely used in common mode filter, multi frequencytransformer, impedance transformer, balance and unbalance converter transformer, inhibition of electronic equipment EMI noise, personal computers and peripheral equipment of USB circuit, liquid crystal displaypanel, power inductors - chip inductor - wire wound inductor - inductance coil inductively manufacturers - low voltage electronic news differentialsignal, car remote control type key.

Includes 2 fixed inductance coil: ring coil, choke coil, the common modecoils, ferrite bead, power inductor, SMD and pin type selection. Widely used in telecommunications, computer, network, communication power supply and peripheral equipment.

3 closed magnetic circuit of high current appearance mount powerinductance characteristic and use: the ideal DC-DC converterinductance, high power, high full inductor, DC resistance is small, suitable for high current, belt or reel to active appearance and packaging deviceused in power supply power supply, VCR VCR supply, LCD TV, portable computers, office automation equipment, mobile communications equipment, DC / DC converter etc. through.

4 RF inductors use: widely used in mobile phones, VCO, TCXO circuitand RF transceiver module, the global positioning system, wireless network, Bluetooth module, communication equipment, LCD TV, camera,notebook, inkjet printer, photocopier, displays the monitor, game machine, color TV, VCR, CD machine and camera, digital camera, carelectronic products

The difference of color ring inductance and winding inductance

In addition to the most common inductance inductance value, and the following common parameters:

The inherent capacitance (associated with the resonant frequency, useoperation frequency inductance is far below this frequency, otherwise there will be questions);

The quality factor (related with circuit function Q is larger, less power consumption is small, higher power, frequency selection function is better);

Rated current (the maximum allowable current through the inductor).

Specific can change depends on the use of the environment, in the high current, high frequency radio, resonant circuit and other fields, when the replacement is still to be careful, the best prior test what you decide.

The characteristic of the:

1 is suitable for power supply circuit.

2 surface adhesion type.

3 the appearance and scale corresponds to EIA specification, not the same standard to choose from.

Solderability and high heat resistance of 4 outstanding, suitable fornormally and reflow soldering.

Use: This product is widely used in micro TV, LCD TV, portable VRC, carcamera, audio, radio, TV tuner, thin cell phone etc..

SMD inductor:

1, surface mount high power inductors.

2, has the advantages of miniaturization, high quality, characteristics of high energy storage and low resistance.

3, the first application in the computer display card, notebook computer,pulse memory program design, and the DC-DC converter.

4, can provide the reel packing is suitable for the appearance of activemount.

Characteristic:

1, flat appearance suitable mount.

Solder end strength of 2, outstanding outstanding.

3, high Q value, characteristic of low impedance.

4, low leakage, low resistance, resistance to feature direct current.

5, can provide tape packaging, convenient mechanized assembly.

Effect

Chip wire wound inductor effect. The fundamental effect: filter, vibration,delay, notch; image statement: "through the DC resistance of communication"

Detailed description: in the electronic circuit, inductance coil forCommunication Co flow effect, it with the resistor or capacitor canconstitute a low-pass or high pass filter, phase shift circuit and resonantcircuit; transformer can communicate coupling, transformer, variable flowand impedance transformation.

Chip wire wound inductor effect is straight resistance, original! DC after field direction inductance occurs when the size is common, will not change. While communication electric is positive and negative changes,so the magnetic field will change, because from the positive (negative) to negative (positive) is a very short time, assuming the first positive potential and rising, so the inductance magnetic fields around were added, the top is the biggest potential, then start to reduce, because the surrounding the presence of a magnetic field, the inductance at the moment will put around the magnetic field is converted to electrical energy, the electrical energy can be maintained for a period of time,whereas the same, so as to prevent the communication power after.
