SRU1028A-470Y

Fixed Inductors

Fixed inductors are used to create an inductance in a static electric circuit. Generally, they comprise one or more loops of conductive wire that are wound around a core material to create the inductance. Typically, a ferrite disk is used for the core material; however, other materials such as ferrite rings, nickel-iron, and beads may also be used. Fixed inductors have a wide range of applications, from telecom use to switching power supplies, amplifiers, and low-noise circuits. Moreover, they have been used in medical applications such as medical imaging and heart rate monitors.

One such example of a common fixed inductor is the SRU1028A-470Y. This particular inductor is constructed with two layers of electroplated steel wound with iron nickel alloy to form the inductance. A plastic bobbin is used to insulate the iron core and protect the inductor from any external interference. It has a range of 0.47-20 μH, DCR of 0.15-7.5 Ohm, and temperature range of -40 to +125°C. These parameters make the SRU1028A-470Y suitable for a wide range of application requirements.

SRU1028A-470Y Application Field and Working Principle

The SRU1028A-470Y is typically used in low noise and medium power supply circuits. In particular, it is commonly used in DC-DC converters, as well as various power management ICs. At low current applications, the inductance is created by the electrical current that passes through the inductor. The electrical current passing through the loops of the core material will induce a magnetic field that creates an opposing force against the current flow. This counter-acting force is what creates the inductance of the inductor.

At higher current applications, the SRU1028A-470Y can also be used as a choke. This is when the inductor is placed in series with current flow, and it begins to create an opposing force to the current flow. This opposing force helps to reduce the current flow as it passes through, resulting in less current being passed through the circuit. This is helpful for protecting sensitive components in power supply circuits from power surges. It can also help to reduce electrical noise in low noise circuits.

Overall, the SRU1028A-470Y is a versatile fixed inductor that can be used for a wide range of applications. With its wide range of parameters and capabilities, it is suitable for many different types of circuits, from power supplies to low noise and switching applications. It provides excellent inductance values and choke abilities for a wide variety of voltage and current ratings.
