Fixed inductors, also known as radio frequency (RF) inductors, are components of electromagnetic devices which block certain frequencies while allowing other frequencies to pass through. PTKM150R-30SM is a type of fixed inductor that has found wide application in various electronic circuits. This article aims to discuss the application field and working principle of PTKM150R-30SM.

PTKM150R-30SM is a high-performance fixed inductor that is designed to replace variable inductors, especially in high-frequency switching and control applications. It offers superior low-loss performance in frequencies up to 3GHz and its high current-handling capability ensures reliable operation in equipment subject to shock or vibration. It has a wide range of application areas such as wireless charging, automotive electronics, RF ID tags, GPS antennas and cellular base stations. It can also be used in various types of audio circuits, medical equipment, and EMI/RFI filtering systems.

PTKM150R-30SM is composed of two parts: a metal core and an inductor coil. The metal core is made of ferrite, an iron-based alloy, which is magnetically active and has high permeability and low losses. The inductor coil is composed of a winded wire with an insulation coating. The coil will produce an electromagnetic field when an alternating current is applied to it, and this field interacts with the metal core, creating a magnetic flux. The flux is transferred to the metal core and returns to the coil, thus creating a magnetic field.

PTKM150R-30SM is capable of providing high-precision inductance performance due to its low DCR and its ability to handle current up to 50A. Its high current-handling capacity allows it to be used in high-power applications such as automotive and power electronics in various equipment. Its shielded design decreases electromagnetic interference to nearby electronic devices, making it an ideal component for various EMI/RFI filtering systems. Besides, its low profile and light weight enable easy integration with other electronic devices.

In conclusion, the PTKM150R-30SM is a high-performance fixed inductor that offers excellent performance in various electronic circuits. It has wide application in wireless charging, medical equipment, audio circuits, automotive electronics, and EMI/RFI filters. Its robust and lightweight design makes it highly suitable for use in high-power applications such as automotive and power electronics where high current and low losses are required. Furthermore, its shielded design ensures that it does not generate any electromagnetic interference.
