Fixed inductors are passive components that consist of a conductor (usually coiled) shaped into a loop and wound around a core. They are typically made with coiled wires of a conducting metal, such as aluminum, copper, or nickel. The SRP5030CA-4R7M is a fixed inductor manufactured by Panasonic used in a variety of applications. The SRP5030CA-4R7M has a high inductance rating of 4.7uH and is rated at a continuous operating current of 2.1A, making it suitable for a variety of power supply and filtering circuits, as well as pulse applications. This article will explore the application field and working principle of the SRP5030CA-4R7M.

Application Field

The fixed inductor SRP5030CA-4R7M is mainly used in switching power supplies, amplitude limit circuits, pulse transformers, input protection / voltage conversion and DC-DC convertors.

The SRP5030CA-4R7M is particularly suited for use as an input protection inductor in power supplies, as it can withstand high voltage transients. The high inductance also helps to reduce the inrush current when the power supply is first connected. The SRP5030CA-4R7M is also suitable for use as an output choke inductor for DC-DC convertors, as the high inductance rating provides a low DC resistance when compared to chokes with lower inductance ratings.

The SRP5030CA-4R7M is also suitable for use in amplitude limit circuits, where the inductor is used to reduce the output amplitude of a signal. This is done by allowing the signal to pass on through the inductor until it reaches a certain amplitude level, at which point the inductor starts to resist the current, limiting the amplitude of the signal that passes through.

The SRP5030CA-4R7M is also a suitable component for use in pulse transformers. Pulse transformers are used to convert high frequency AC signals to low frequency AC signals, and the SRP5030CA-4R7M helps to provide the high frequency AC signal that is necessary for the transformer to function.

Working Principle

The working principle of a fixed inductor such as the SRP5030CA-4R7M is based on the property of inductance, which is the ability of an inductor to resist a change in current. Inductors work by generating a magnetic field in response to a change in current, which in turn generates an opposing electric field. This therefore opposes the change in current and prevents the current from changing too quickly.

In the case of the SRP5030CA-4R7M, the inductor\'s inductance of 4.7µH allows it to resist changes in current up to 2.1A. This high resistance to changes in current makes the inductor ideal for a variety of power supply, filtering, pulse and other applications.

In addition to the inductance rating, the SRP5030CA-4R7M also has a rated saturation current of 2.1A. This means that the inductor can handle a maximum current of 2.1A without becoming saturated and losing its inductance. The rated peak current is 4.5A, which means that the inductor can safely handle peak currents of up to 4.5A.

The SRP5030CA-4R7M also has a very low DC resistance of 0.073Ω. This low DC resistance is important in applications such as DC-DC convertors, where a low resistance is beneficial in order to ensure that the convertor works efficiently.

The SRP5030CA-4R7M is also rated for a maximum operating temperature of 100°C. This means that the inductor can safely be used in a variety of temperature conditions and can handle temperature extremes without any damage to the winding or core.

Fixed inductors such as the SRP5030CA-4R7M are used in a variety of applications, including power supply, filtering, amplitude limit circuits, pulse transformers, input protection and DC-DC convertors. The SRP5030CA-4R7M is rated for a high inductance of 4.7µH, a rated operating current of 2.1A, a rated peak current of 4.5A, a low DC resistance of 0.073Ω and a maximum operating temperature of 100°C. With these characteristics, the SRP5030CA-4R7M is an excellent choice for any application requiring a fixed inductor.
