4922-30J

Fixed inductors are one of the most commonly used electronic components in virtually any electrical application. They are also known as inductance coils or chokes. The 4922-30J is a fixed inductor found in a wide variety of applications, such as embedded systems, signal processing, power management, and communication electronics. This type of inductor is also used for ultra-low-noise DC-DC converters, RF-amplifier stages, and EMI/RFI suppression.

The 4922-30J has a maximum current rating of 2.2A and can handle peak currents up to 4A. It has a manufacturer rated inductance of 180μH at 100kHz and 1.028V DC. The inductor is composed of a cylindrical core made up of a ferrite material and a copper windings. It is encapsulated in a plastic or epoxy housing for insulation and improved mechanical performance.

The working principle of the 4922-30J is based on Faraday\'s law of induction, which states that a voltage is induced in a conductor that is in a changing magnetic field. When a current is passed through the windings of the inductor, a magnetic field is generated, which, in turn, induces a voltage in the windings. The magnitude of the voltage depends on the number of winding turns, the frequency of the AC current, and the inductance value of the inductor.

The 4922-30J can be used in a wide variety of applications due to its versatility and varied electrical properties. It can be used in power supplies for regulating voltage and current; for filtering AC and DC signals; for suppressing high-frequency noise; for timing circuits; and for matching impedances. It is also used frequently in switched-mode converters, where the inductor charges and discharges during each cycle of the circuit.

In summary, the 4922-30J is an exemplary fixed inductor with a variety of electrical properties and a wide range of uses. Its versatile design allows it to be used in embedded systems, signal-processing components, noise-suppression circuits, power supplies, and many other applications. Its working principle is based on Faraday\'s law of induction, which states that a voltage is induced in a conductor that is in a changing magnetic field.
