What is Chip Inductors
Chip inductors are also called power inductors, high current inductors and surface mount high-power inductors. It has the characteristics of miniaturization, high quality, high energy storage and low resistance. The inductance in the general electronic circuit is a hollow coil or a coil with a magnetic core, which can only withstand a low voltage through a small current; The power inductors also have air core coils and magnetic cores. The main feature is that they are wound with thick wires and can withstand tens, hundreds, thousands, or even tens of thousands of amps. Power chip inductors are divided into two types: with and without magnetic cover, which are mainly composed of magnetic core and copper wire. It mainly plays the role of filtering and oscillation in the circuit

Classification of Chip Inductors
There are four types of chip inductors, namely, wound type, laminated type, braided type and film chip inductors. Commonly used are winding type and laminated type. The former is the product of miniaturization of traditional wound inductors; The latter is made by multi-layer printing technology and laminated production process, and its volume is smaller than that of wound chip inductors. It is a key product developed in the field of inductive components.
Winding type
It is characterized by a wide range of inductance (MH ~ H), high accuracy of inductance, small loss (i.e. q), large allowable current, strong inheritance of manufacturing process, simplicity and low cost. However, it is limited in further miniaturization. The ceramic core wound inductor can maintain a stable inductance and a high Q value at such a high frequency, so it occupies a place in the high frequency circuit.
NL series inductance of TDK is wound type, 0.01~100uh, accuracy 5%, high Q value, which can meet general requirements.
NLC type is applicable to power circuit, and the rated current can reach 300mA; NLV type is of high Q value, environmental protection (recycled plastic), and can be interchanged with NL; Nlfc has magnetic screen, which is suitable for power cord.
Laminated type
It has good magnetic shielding, high sintering density and good mechanical strength. The disadvantages are low qualification rate, high cost, small inductance and low Q value.
Compared with the wound chip inductor, it has many advantages: small size, which is conducive to the miniaturization of the circuit, closed magnetic circuit, will not interfere with the surrounding components, nor will it be interfered by adjacent components, which is conducive to the high-density installation of components; Integrated structure, high reliability; Good heat resistance and weldability; Regular shape, suitable for automatic surface installation production.
FBELE mlk inductor has small size, good solderability, magnetic screen, high-density design, monolithic structure and high reliability; The MLG type has a small sensing value and uses high-frequency ceramics, which is suitable for high-frequency circuits; Mlk type operating frequency 12GHz, high Q, low sensitivity (1n~22nh)
Film chip
It has The characteristics of high Q, high precision, high stability and small volume in the microwave frequency band. The internal electrodes are concentrated on the same level, and the magnetic field distribution is concentrated, which can ensure that the device parameters change little after installation, and show good frequency characteristics above 100MHz.
Braided type
The characteristic is that the unit volume inductance at 1MHz is larger and smaller than other chip inductors, and it is easy to install on the substrate. Micro magnetic element for power processing.

Genaral Questions About SMD Inductor
Chip inductance (unit: Micro Heng)（ μΗ）
Power SMD inductors are divided into two types, with and without magnetic covers, which are mainly composed of magnetic cores and copper wires.
SMD inductors can be divided into wound type, laminated type, braided type and thin film chip inductors, of which two types are commonly used: wound type and laminated type. According to the product type, it can be divided into: chip inductors, power inductors, chip shield inductors, chip stacked inductors, high-power inductors, and integrated inductors.
① Generally, the color of the chip capacitor is darker. The resistance of the multimeter is open and there is no mark. ② The chip inductors are generally white, wound, etc. the resistance of the multimeter is short circuited, and the inductance value is generally marked above.
The inductor is made of a coil. Its functions are: (1) to isolate and filter the AC signal; ⑵ form a resonant circuit with capacitors and resistors; (3) tuning and frequency selection inductance.
Chip inductors are generally used for radio frequency (RF) and wireless communication, information technology equipment, radar detectors, automotive electronics, cellular phones, pagers, audio equipment, PDSA (personal digital assistant), wireless remote control systems and low-voltage power supply modules.
