Fixed inductors, such as the 23330C, are passive electronic components which are widely used in various electrical circuits. They are constructed of a coil wound around a fixed iron core, and their general design consists of a shaft, a core, a collar, and a support member. The internal construction of fixed inductors vary based on their applications, and depend on the types of materials used, whether they are air-core, and the number of windings.

The 23330C is a high-performance fixed-inductance current-sense inductor from Wurth Electronics. With a core size of 5835 mm, it has an operating temperature range of -40°C to 85°C and a rated current of 13A. It is made of iron powder, has an air-core inductance of 1.4mH, and a typical Q-factor of 96. It is suitable for switching power supplies and power regulators, and has very low hysteresis loss.

Fixed inductors are mainly used in applications such as motors, drive circuits, high-frequency oscillators, pulse generators, switching power supplies, and regulators. Generally, when the inductor is connected to a power supply, current flows through the windings of the core and creates a magnetic field around it. This magnetic field is then used to store and release energy, and the energy release is called inductance. The output of the inductor varies depending on the current which is applied to it, and the output will increase or decrease as the current is changed.

In the case of the 23330C, it is mainly used in current sensing applications. This is achieved by connecting the inductor in series with a shunt resistor, such that the current passing through the resistor is inversely proportional to the inductor’s output. At a given frequency, the current flowing through the inductor is proportional to its rated current, so by measuring the current passing through the inductor, a precise current measurement can be obtained.

The 23330C is also used in DC-DC converters. This is due to its high inductance value, meaning that it can store the energy for a longer period of time. As such, the current provided by the converter is maintained for a longer period of time before diminishing. What is more, the inductor’s magnetic properties allow it to reduce the noise generated by the converter and also reduce electromagnetic interference.

In conclusion, the 23330C is a highly efficient, low-profile fixed-inductance current-sense inductor. Its high inductance and low resistance make it ideal for current sensing and DC-DC converter applications, while its low hysteresis losses make it a reliable component for reliable operation in high-power applications.
