Fixed Inductors

Fixed inductors are electrical components that store electrical energy in the form of a magnetic field. They are most commonly used in circuits to produce a fixed inductance, helping to filter out certain frequencies from the audio spectrum. The 2256R-561J is a type of fixed inductor that is suitable for a wide range of applications.

2256R-561J Application Field

The 2256R-561J is perfect for use in a wide variety of audio applications. Its low self-inductance of 0.093mH allows it to be used in low-noise amplifier stages, as well as high-power ones. Its high maximum operating temperature of 85°C also makes it well-suited for use in high-heat environments. This inductor is also able to effectively reduce EMI interference in radio frequencies, making it highly desirable for any RF application. The range of applications for the 2256R-561J is quite wide and it is suitable for virtually any circuit that requires a fixed inductor.

2256R-561J Working Principle

The 2256R-561J has a metal core surrounded by a coil of wire, which is usually either copper or aluminum. This wire is called winding wire. The current running through the wire will create a magnetic field around the core, which induces a voltage in the coil. The strength of the induced voltage depends on the number of turns in the coil and the rate at which the current changes. When the current flowing through the coil changes, it creates a magnetic field and an induced voltage that opposes the current, creating resistance. This induced resistance is called inductance. The strength of the magnetic field and the induced voltage vary depending on the inductance of the coil. The 2256R-561J has an inductance of 0.093 mH, which is relatively low. This means that the induced resistance is also relatively low, allowing it to be used in low-noise amplifier stages without introducing too much distortion.

Conclusion

The 2256R-561J fixed inductor is an excellent choice for many applications, due to its low inductance and high maximum operating temperature. It is particularly suitable for use in low-noise amplifier stages and in applications that require effective EMI shielding and RF filtering. The 2256R-561J is a reliable and efficient component that is suitable for virtually any circuit that requires a fixed inductor.
