SP1210R-153K

Fixed Inductors

Fixed inductors, also known as "fixed inductance coils," are static components often used in electronic circuits to store energy in the form of a magnetic field or to provide the means to filter, transmit, or receive a signal. The SP1210R-153K is a type of fixed inductor and can be used in a variety of applications. This article will discuss the characteristics of the SP1210R-153K, the application fields it is suitable for as well as its working principle.

Characteristics: The SP1210R-153K inductor is made up of a ferrite core and wire winding. The winding consists of an enameled metal wire and the ferrite core is filled with an insulating epoxy resin to prevent it from shorting out when it is in use. This type of inductor is constructed such that its inductance remains constant, regardless of the amount of current passing through the wire winding. Its rated inductance is 153 μH ±20% and its rated current is 3.8A. It has an operating temperature range of -40 to +105°C.

Application Fields: The SP1210R-153K is a type of surface mount fixed inductor that is primarily used in DC-DC converters, power supplies, switching power supplies, and power conversion circuits, among other electronic applications. Its high rated current means that it can be used in high-power applications with high currents, and its high rated inductance enables it to be used in circuits where an increase in inductance is required.

Working Principle: When the SP1210R-153K inductor is connected to a DC voltage source, a current starts to flow through the winding. As the current flows through the winding, a magnetic field is generated around the inductor. This magnetic field stores energy, which is known as inductance. The amount of inductance is related to the number of turns in the winding, the diameter of the wire, and the permeability of the core material. Since the SP1210R-153K inductor has a fixed number of turns and a fixed core material, its inductance is constant regardless of the amount of current passing through the winding.

The SP1210R-153K is a type of fixed inductor that can be used in a variety of applications, due to its high rated current and inductance. It is often used in high-power applications where high current levels are required, and in circuits where an increase in inductance is desired. Its operating temperature range of -40 to +105°C makes it a suitable choice for use in a wide range of operating environments.

In summary, the SP1210R-153K is a fixed inductor used in a variety of electronic applications like DC-DC converters, power supplies, and power conversion circuits. It has a rated inductance of 153 μH ±20% and is constructed such that its inductance remains constant regardless of the amount of current passing through the winding. Its high rated current and inductance make it suitable for use in high-power applications, and its operating temperature allows it to be used in a wide range of operating environments.
