SRP1055-4R3M

Fixed inductors, such as SRP1055-4R3M, are widely used in a variety of electronic circuits. The main purpose of a fixed inductor is to store energy in the form of a magnetic field, allowing electrical current to pass through it in either direction without depending on power from external sources.

SRP1055-4R3M is a miniature, surface-mount, high current inductor featuring an induction range of 4.3µH to 10.5µH, a resistance of 0.072ohm to 0.270ohm and a tolerance of ±10%. It has a nominal current of 3.2A, and a maximum high-frequency rated current of 5A. SRP1055-4R3M is a versatile device, mainly used in DC/DC converter, power supply, switching power amplifier, voltage regulator, and automotive applications.

The working principle of SRP1055-4R3M is based on the generation of energy in the form of a magnetic field when an electrical current is passed through a conductor. This magnetic field can be harnessed to induce an electrical current in a nearby conductor. Any changes in the current passing through the first conductor will cause a change in the magnetic field, which in turn will cause a change in the voltage in the second conductor.

The SRP1055-4R3M has several components including a magnet, an iron core, and an electromagnetic coil. The magnet creates a magnetic field when an electrical current passes through the coil. The iron core increases the inductance of the device, while the electromagnetic coil acts as a conduit for the electrical current, which also allows the electrical current to be easily converted into a magnetic field.

SRP1055-4R3M provides several advantages over other inductors. It has a low resistance, making it suitable for high current applications. Additionally, the core of the inductor can be designed to be either ferrite or powdered iron, providing flexibility in the design process. SRP1055-4R3M also has a high self-resonant frequency, meaning that it is less likely to be influenced by external electrical noise.

The SRP1055-4R3M is a versatile and reliable device, suitable for use in a variety of electronic circuits. Its main application fields include DC/DC converters, power supplies, switching power amplifiers, voltage regulators, and automotive applications. With its high current capability, low resistance, and high self-resonant frequency, it is an excellent choice for applications requiring high-frequency, high-current operation.
