Fixed inductors, or known as a "choke," are electrical components that act as a conductor of electrical charge. The 2474R-50K is an example of a fixed inductor and is primarily used to reduce voltage ripple in power supply circuits.

Inductors are composed of a coil of wire commonly wound around a magnetic core. The 2474R-50K is composed of an Axial Lead Ferrite Core, and is painted red for easy identification. Its inductance value is approximately 50K ohms (50k Ohm) and its current rating is 250mADC (250 mA DC). The current that passes through the inductor produces a magnetic field and creates a voltage drop across its leads. This voltage drop can be used to reduce the voltage ripple in a power supply circuit.

The 2474R-50K can be used for a number of applications such as increasing efficiency in power supplies, providing over-voltage protection, and as filters to reduce noise in electronic circuits. It is often used in power supplies as an inductor for an AC to DC converter and as an inductor-capacitor (LC) for power factor correction in AC-DC converters. The 2474R-50K can also be used in AC noise suppression circuits, for power line conditioning, and as a high-pass filter in amplifier circuits. It is also used to attenuate noise from high frequency switching DC-DC converters.

When used in AC-DC converters, the inductor acts to reduce the voltage ripple by allowing the current to flow in one direction due to the presence of the magnetic field. The voltage drop of the inductor is equal to the amount of current passing through it multiplied by its inductance. The voltage drop reduces the power supply voltage and reduces the ripple created by the power supply.

Inductors can also reduce noise from switching DC-DC converters. Switching DC-DC converters are used to convert high power levels from one voltage source to another. The noise generated by the switching action can cause interference in other electronic circuits, so an inductor is used to reduce the noise by limiting the amount of power to the switching DC-DC converter, allowing it to function at a lower power level.

The 2474R-50K is a versatile inductor that can be used in many applications. It is capable of providing lower voltage ripple for AC-DC converters and reducing noise from switching DC-DC converters. It can also be used as an inductor-capacitor for power factor correction in AC-DC converters, for over-voltage protection, and as a filter to reduce noise in electronic circuits.
