Fixed Inductors

A fixed inductor, also known as an inductor, is an electronic component that is used in several electrical and electronic applications. It is a passive device that is designed to store electromagnetic energy in the form of a magnetic field. It is typically used in AC power systems, communications systems, and other commercial and industrial installations that require some form of electrical energy storage.The 4445R-18K is a type of fixed inductor that is widely used in various applications. It is a radial leaded, high-current power choke inductor with a wide range of operating temperature, and is ideal for RF circuits, DC to DC converters, switching power supplies, choppers, audio circuits, automotive applications, and more.The 4445R-18K is a high current power choke inductor with a rated inductance of 18K Ohms. It is designed to provide a low resistance, high current capacity in applications that require a wide range of operating temperature. It consists of a grade A magnet wire enclosed in a Y-type core with the size of 16.2*11.2 mm. It works by storing energy in the form of a magnetic field. This energy can later be discharged to a load when needed.The working principle behind 4445R-18K is based on Faraday’s law of induction. It states that when a current flowing through an inductor is changed, the rate of change in its magnetic flux will induce an electromotive force (EMF) in the coil. This EMF is directly proportional to the rate of change of flux. In the 4445R-18K, the current flowing through the inductor creates a magnetic field around the coil and induces an EMF in the coil. This EMF can be used to store energy in the form of a magnetic field.The 4445R-18K is a versatile fixed inductor and finds wide use in a variety of applications as mentioned above. It is used mainly in RF circuits, such as amplifiers and filters for high frequency applications. It is also used in DC-DC converters, switching power supplies, choppers, and audio circuits. It is also used in automotive applications, where it is used to eliminate voltage ripple in the power sources and improve the efficiency of the circuit. Moreover, 4445R-18K is one of the most cost effective solutions for eliminating unwanted ripple. It is highly reliable and resistant to shock, vibration, and temperature. Its wide operating range, low resistance, and high current capacity make it an ideal choice for a variety of applications.The 4445R-18K fixed inductor is one of the most widely used components in many electronic and electrical applications. Its versatile nature makes it an ideal solution for a variety of applications, including RF circuits, DC-DC converters, switching power supplies, choppers, audio circuits, and automotive applications. It is also an efficient and reliable solution for eliminating unwanted voltage ripple and improving the efficiency of the circuit.
