Що є типи з чіп індуктори?

Є є чотири основні типи з мікросхема індуктори

Два типи з обмотки і ламінування є зазвичай використовується. The former is the product of miniaturization of традиційні обмотки індуктори. the останній is made of багатошаровий друк технологія and laminated production process, and the volume is smaller than the wound chip inductor, which is the focus of the development of products in the field of inducors.

1. Намота лінійна мікросхема індуктор
It is characterized by a wide range of inductance (mH ~ H), high inductance precision, low loss (that is, large Q), large allowable current, strong inheritance of the production process, simple, low cost, but the disadvantage is that it is limited in next miniaturization. Ceramic-core wound inductors can can maintain stable inductance and quite quite high Q value at such high frequencies, so they occupy a place in висока частота схеми.

TDK's NL series inductors are winding, 0.01~100uH, accuracy 5 percent , high Q value, can meet the general needs.

NLC type is is suitable for power supply circuit, rated current up to 300mA; NLV type is is high Q value, environmental protection (перероблений пластик), can be interchangeable with NL; The NLFC has a magnetic screen and is suitable for power cables.

2. ламінований мікросхема індуктор
It has good magnetic shielding property, high sintering density and good mechanical strength. the disadvantage are low pass rate, high cost, small inductance and low Q value.

Compared with coil inductors, it has many advantages: small size, conducive to the miniaturization of the circuit, closed magnetic circuit, will not interfere with the surrounding components, will not be interfered by adjacent components, conducive to the high-density installation of components; Integrated structure, high reliability; Good heat resistance and weldability; The shape is regular, suitable for automatic surface mounting production.

TDK MLK inductance, small size, good weldability, magnetic screen, high-density design, monolithic structure, high reliability; MLG type has small sensing value and adopts high frequency ceramic, which is suitable for high frequency circuit; MLK type operating frequency 12GHz, high Q, low sensing value (1n~22nH)

3. плівка мікросхем мікросхема індуктор
It has the characteristics of maintaining high Q, high precision, high stability and small size in the microwave frequency band. The internal electrodes are concentrated in the same layer, and the magnetic field distribution is concentrated, which can ensure that the device parameters do not change much after installation, and show good frequency characteristics above 100MHz.

4. Плетений мікросхема індуктор
It is characterized by larger inductance per unit volume than other chip inductors at 1MHz, smaller volume, and easy to install on the substrate. Miniature magnetic components for power processing.

In practical applications, the application should be selected according to the situation, and the application effect should be considered as well as the material cost. Для більше інформації, будь ласка contact us at sales@xfullstar.com
