Fixed inductors are one of the most common electronic components in technology today. The SPM10040T-4R7M-HZ is one of those components, and provides a reliable, efficient solution for many types of applications.

On a basic level, fixed inductors are electrical components designed to resist changes of current in an electrical circuit. They achieve this by storing a certain amount of energy in a magnetic field. In the case of the SPM10040T-4R7M-HZ, it is a radial, wire-wound component that is particularly suited for SWRS, output coupling, voltage doubling, and noise suppression applications.

The SPM10040T-4R7M-HZ is a 4.7mH inductor which provides a high degree of accuracy and stability. In particular, its construction results in a very low self-inductance, making it suitable for high current, high frequency applications. Its wire construction also helps to reduce leakage inductance.

The SPH10040T-4R7M-HZ is able to handle a maximum current of 7A and has a temperature range of -40°C to +85°C. It can also operate at a maximum frequency up to 250KHz. The inductor also has a low DCR rating of 40mΩ, making it very efficient at high temperatures.

In terms of application field, the SPH10040T-4R7M-HZ is suitable for high power supply and DC filter designs, power supply switching circuits, automotive voltage regulators, and high-efficiency switching mode power supplies. Its ability to handle high currents, along with its low DC resistance, makes it an ideal component for a wide range of applications.

In terms of working principle, this fixed inductor operates by storing energy in a magnetic field. As soon as current is drawn or released from the inductor, the magnetic field will release or absorb energy in the form of voltage. This voltage then regulates the current flow in the circuit, ensuring a consistent and reliable operation.

In conclusion, the SPH10040T-4R7M-HZ is a 4.7mH fixed inductor which is highly suitable for a variety of applications, due to its low DC resistance and ability to handle high currents and frequencies. It is particularly suitable for power supply switching circuits, automotive voltage regulators, and high-efficiency switching mode power supplies. The SPH10040T-4R7M-HZ operates by storing energy in a magnetic field, which regulates current flow, ensuring consistent performance.
