1812-103J

Fixed Inductors

Fixed inductors are a type of electronic component consisting of a coil of wire with two terminals. Fixed inductors are widely used in various electronic circuits for purposes such as signal filtering, power-supply regulation, and signal distortion. The 1812-103J is an example of a fixed inductor that is used in radio frequency (RF) applications.

Application Field and Working Principle of 1812-103J

The 1812-103J fixed inductor is a high-Q ceramic surface- or mounted device designed to offer low loss and low impedance in radio frequency circuits. The inductor is suitable for use in RF signal processing applications such as amplifiers, filters, impedance matching, and radio receivers. The 1812-103J can handle frequencies as high as 10 GHz and has an inductance range of 0.1µH to 47µH.

The working principle of the 1812-103J fixed inductor is based on Faraday\'s Law of Electromagnetic Induction, which states that when a conductor is placed in a changing magnetic field, an electric current is induced in the conductor. In the case of the 1812-103J, an electric current is induced when a magnetic field is applied to the coil of wire. This induces a varying current in the inductor, which in turn causes an opposition to changes in current flow in the circuit as per the principle of impedance.

The 1812-103J has a ceramic slug core, which gives the inductor its high-Q rating. The high-Q rating means that the 1812-103J offers low losses of current, allowing for higher efficiency in the bi-directional current flow. Furthermore, the large inductance range and high-Q core make the 1812-103J ideal for RF amplifiers, filters, and impedance matching in radio and telecommunications devices.

Conclusion

The 1812-103J fixed inductor is an ideal choice for RF signal processing applications and offers low losses and impedance in radio frequency circuits. The inductor is suitable for use in amplifiers, filters, impedance matching, and radio receivers and has an inductance range of 0.1µH to 47µH and is capable of handling frequencies of up to 10 GHz. The high-Q ceramic slug core helps it deliver a high-Q rating and makes the 1812-103J ideal for RF amplifiers, filters, and impedance matching in radio and telecommunications applications.
