SPD62R-473M Datasheet/PDFFixed Inductors are one of the oldest and most useful components in the fields of electronics and electrical engineering; as far back as the invention of the induction coil in 1891, they have been used in a variety of applications and are still widely employed today. The SPD62R-473M is a type of fixed inductor suitable for high-frequency and high-current applications. It is commonly used in switch-mode power supplies, wireless communications systems, and high-speed LAN systems.
Design
The SPD62R-473M is a self-shielded inductor; the body of the component is made from a ferrite core surrounded by an ABS resin insulation material. The device requires no external shielding, making it compact and lightweight. It has a rated current up to 7.5A, and an inductance of 4.7uH. Its operating temperature range is between -25°C and 80°C.
Structure
The SPD62R-473M consists of two parts: a housing and a core. The core is made up of a ferrite material, while the housing is comprised of an ABS resin insulation material. The inductance value is determined by the size of the ferrite material, the thickness of the insulation material, and the dimensions of the component.
Applications
The SPD62R-473M is used in a number of applications, including power supplies, DC-DC converters, switched-mode power supplies (SMPS), and voltage-regulated modules. It is also commonly used in personal computers, laptops, cellular phones, and other electronic equipment that requires high-frequency and current-handling capabilities. Additionally, it can be used in technical instruments, such as oscilloscopes, timers, and counters.
Working Principle
The SPD62R-473M is an inductor, meaning that it resists changes in the flow of current. When a current is applied to the device, the inductance value determines the rate at which the current changes. The rate of change is inversely proportional to the inductance value; the higher the inductance, the slower the rate of change. This is known as the inductor\'s "impedance", and it is what makes the device useful as a power-handling component.
The SPD62R-473M is also a reactive component, meaning that it stores and releases energy. In the presence of an alternating current, the device absorbs energy in the form of a magnetic field. This stored energy is then released back into the circuit when the current flow changes direction, resulting in reduced energy losses. The device is thus useful for controlling the flow of current in high-efficiency applications.
Conclusion
The SPD62R-473M is a high-performance fixed inductor designed for high-frequency and current-handling applications. It has a lightweight and compact form factor, and requires no external shielding. It is commonly used in power supplies, DC-DC converters, switched-mode power supplies, voltage-regulated modules, and other electronic equipment. Its ability to absorb and release energy makes it ideal for applications where power efficiency is critical.
