4302R-183K

Fixed inductors are components that store electromagnetic energy and help define the operating currents in an electrical or electronic system. They are typically composed of a coil of insulated wire, typically copper or aluminum, and are found in power supplies, amplifiers, and other electronic circuits. One of the most popular fixed inductors is the 4302R-183K, which is used in a variety of applications.

The 4302R-183K is a general-purpose inductor with a rated current ranging from 0.2A to 1.8A. It features a rated inductance of 1uH to 30mH, a low profile of 5.4mm, and has an operating temperature of -55C to +105C. Its inductance is relatively stable over low frequencies, but decreases slightly with higher frequency applications due to its higher self-resonant frequency and reduced maximum current capability.

The 4302R-183K has a wide range of applications, including power supplies, AC power converters, DC-DC converters, high-frequency switching amplifiers, direct current amplifier circuits, radio frequency amplifiers, audio amplifiers, and voltage-controlled oscillators. It is also suitable for use in automotive and industrial applications.

The working principle of the 4302R-183K is quite simple. When a current flows through the winding of the inductor, an electromagnetic field is created around the winding. This field induces a voltage across the winding which results in an opposing force against the current. This inductive reactance is referred to as the inductor’s impedance, and is capable of significantly slowing down any rising or falling current.

The 4302R-183K is designed to be used together with capacitors to form a filter circuit. The combination of inductors and capacitors can be used to filter out unwanted signals and noise in order to produce a clean signal. As the frequency of the incoming signal increases, the impedance of the inductor is increased, while the impedance of the capacitor decreases. This results in the signal being attenuated, which can reduce the effects of noise on the desired signal. This is known as a low-pass filter.

The 4302R-183K is a versatile fixed inductor, and its range of applications and simple working principle make it well suited for use in a variety of circuits. Its low profile and operating temperature make it especially suitable for automotive and industrial applications, while its frequency and current capability make it suitable for use in high-frequency switching, radio frequency, and audio applications.
