SMD inductor package size table, what are the classifications of SMD inductors, let's follow Dongguan Yite inductor customization manufacturers to understand:
Common chip inductors are divided into the following categories:
Wound type. It is characterized by a wide range of inductance (MH h), high inductance accuracy, small loss (i.e., large Q), large allowable current, strong inheritance of manufacturing process, simplicity, low cost, etc., but the disadvantage is that it is limited in further miniaturization. Wire-wound chip inductors with ceramic cores are able to maintain a stable inductance and a fairly high Q value at such high frequencies, thus occupying a place in high-frequency circuits.
TDK's NL series inductors are wirewound and have a package size of 001 100UH, accuracy 5%, high Q value, can meet general needs.
NLC type is suitable for power supply circuits, with rated current up to 300mA; The NLV type is a high Q value, environmentally friendly (recycled plastic), and is interchangeable with NL; The NLFC has a magnetic screen for use with power cords.
Laminated type. It has good magnetic shielding, high sintering density and good mechanical strength. The disadvantages are low pass rate, high cost, small inductance, and low Q value.
Compared with wirewound chip inductors, it has many advantages: the small package size of SMD inductors is conducive to the miniaturization of circuits, the magnetic circuit is closed, and it will not interfere with surrounding components and adjacent components, which is conducive to the high-density installation of components; Integrated structure, high reliability; Good heat resistance and weldability; The shape is regular, and it is suitable for automatic surface mount production.
TDK's MLK type inductor, small size, good solderability, magnetic screen, high-density design, monolithic structure, high reliability; The MLG type has a small inductance value, and uses high-frequency ceramics, which is suitable for high-frequency circuits; MLK type operating frequency 12GHz, high Q, low inductance (1N 22NH).
Film-disc type. It has the characteristics of high Q, high accuracy, high stability, and small size in the microwave band. The inner electrodes are concentrated at the same level, and the magnetic field distribution is concentrated, which can ensure that the device parameters do not change much after mounting, and show good frequency characteristics above 100MHz.
Braided type. It is characterized by a larger inductance per unit volume at 1MHz than other chip inductors, a smaller size, and easy mounting on a substrate. Used as a miniature magnetic component for power handling.
These are the common classifications of chip inductors, each with its own unique characteristics and application scenarios. When selecting the right chip inductor, it is necessary to consider the actual needs and circuit requirements.
In addition, with the continuous progress of science and technology and the diversification of application needs, chip inductors are also developing and innovating. In the future, with the trend of miniaturization and high frequency of electronic devices, chip inductors will continue to play an important role and contribute to the performance improvement of electronic devices and energy conservation and emission reduction.
