HK2125R18J-T

Fixed inductors are used in a wide variety of high frequency circuits, such as antennas, power supplies, and electronic ballasts. In fixed inductors, the coil winding is not tunable to frequency or current, and as such, the inductance remains constant. The HK2125R18J-T is a type of fixed inductor and is used in a wide variety of applications.

The HK2125R18J-T is a bipolar device which is used in both analogue and digital circuits. It is commonly used in audio, radio and television transmitter applications, as well as in high voltage power supplies. The size of the device is 0.25” by 0.20” and it features a type-N coaxial connector, which makes it well suited for use in high frequency electrical systems.

The basic operating principle of the HK2125R18J-T is based on the fact that inductors store energy when an electrical current is applied to them. The coil winding is formed by wrapping a conductor, usually copper in the case of the HK2125R18J-T, around a core material which can be either ferromagnetic or non-magnetic. When the current is applied to the coil, it creates an electromagnetic field around it, and this field is responsible for storing the energy.

The amount of energy stored in the coil depends on the value of inductance, which is proportional to the size of the core, number of windings and the material used. The HK2125R18J-T has a nominal inductance of 18 µH and can handle currents up to 1.2 A. The device also features excellent temperature stability and is RoHS compliant.

In addition to its application in radio frequency, high voltage and power supply systems, the HK2125R18J-T is also used in digital circuits. This device is often used in switch mode power supplies (SMPS) to filter out high frequency noise, and also in microcontroller applications. The device has excellent saturation characteristics and can handle high frequency switching edges with ease, making it well suited for use in digital systems.

The HK2125R18J-T is an excellent choice for applications requiring a high quality fixed inductor. It is small and compact, has excellent temperature stability and has high current capabilities. Its size and co- axial connector makes it suitable for use in a variety of high frequency applications.
