Fixed Inductors

Fixed inductors are passive electronic components that use the stored energy of magnetism to achieve signal inductance. They are typically found in the signal conditioning circuits of radios, receivers, and transmitters and are also used in high-frequency power supply circuits. SWS-0.30-176 is one of the most commonly used fixed inductors due to its wide range of applications and its ability to provide efficient inductive resistances.

Application Field

SWS-0.30-176 fixed inductors feature maximum current ratings of up to 0.30 amperes and maximum inductance values of up to 176 mH. This relatively high current rating and inductance value make it ideal for a variety of applications including, but not limited to, radio broadcasts, receivers, amplifiers, and power supplies.Due to its relatively low DC resistance, SWS-0.30-176 is highly suitable for use in signal conditioning circuits, especially for signals with higher frequencies. It is also suitable for use where high-frequency supply current is required, such as in power supplies.

Working Principle

The working principle of SWS-0.30-176 fixed inductors is based on the electromagnetic principles of inductance, the flux linkage, and the electromotive force (EMF). By passing a current through a cylindrical coil of wire, an electromagnetic field is generated, causing the electrons in the wire to align in a magnetic field. This magnetic field causes a flux linkage that exists at a distance (given by the coil’s inductance) from the wire, inducing an EMF in the circuit. The inductance of a fixed inductor is defined as the amount of inductance in the circuit, inversely proportional to the amount of current, given a certain flux density. The higher the current, the lower the inductance, and vice versa. For SWS-0.30-176, the inductance values of up to 176 mH are achievable with the maximum current rating of 0.30 amperes, allowing for a dynamic range of inductance.

Conclusion

In summary, SWS-0.30-176 is one of the most commonly used fixed inductors due to its wide range of applications and its ability to provide efficient inductive resistances. Its maximum current rating of up to 0.30 amperes and maximum inductance values of up to 176 mH makes it suitable for use in a variety of radio, receiver, amplifier, and power supply applications. Its working principle is based on the principles of inductance, flux linkage, and electromotive force, giving it the ability to provide highly dynamic inductance values with its maximum current ratings.
