Fixed inductors are electrical components that store electrical energy in the form of a magnetic field when a steady current passes through them. The SPD127R-273M is a popular fixed inductor with proven reliability and versatility, and it is suitable for a variety of applications. In this article, we will explore the application field and working principle of the SPD127R-273M.

Application Field of the SPD127R-273M

The SPD127R-273M includes a ferrite-core inductor with 10% tolerance and a wide range of available inductance values from 0.22μH to 47μH. Its ultra-low profile enables it to be widely used in various electronic products where space is limited such as data and power integrated circuits, computer peripherals, multimedia applications, and consumer electronics. The operating temperature range of −40°C to +125°C makes it suitable for on-board as well as lead-free reflow and wave soldering.

In addition, the SPD127R-273M provides more than 40% higher inductance ratios compared to similar gapless inductors available on the market. This is a great advantage when designing for different applications.

The SPD127R-273M is available in several standard packages like SOT-25, SOT-23, and SOT-89, making them ideal for use in board-level designs. Its small size, low profile, high current handling capability, and high level of inductance make the Gapless Low Profile Inductor very popular.

Working Principle of the SPD127R-273M

The SPD127R-273M consists of a ferromagnetic core that is wrapped with a copper wire coil. When current is applied to the inductor, a magnetic field is created and stored inside the ferromagnetic core. This stored energy is released in the form of electric current when the coil is exposed to the alternating magnetic field generated by the electrical current that flows through it. This process is known as induction.

The inductance of the SPD127R-273M is very high due to its high permeability compared to other electrons. Its high inductance makes it particularly suitable for applications that require a large amount of energy to be stored, such as lighting, power converters, and DC-DC voltage adapters. In addition, its high inductance is not affected by temperature changes, making it very reliable.

The SPD127R-273M is also very efficient, owing to its high permeability. Its winding resistance is also very low, allowing it to transfer maximum power in a given circuit configuration. Furthermore, its high saturation current capability and low equivalent series resistance make it perfect for high-current applications.

The SPD127R-273M’s unique design makes it very reliable and resilient, allowing it to perform consistently within its operating temperature range and provide extended application lifetime. It is also RoHS-compliant, making it suitable for use in environmentally-conscious designs.

Conclusion

The SPD127R-273M is a popular fixed inductorwith proven reliability and versatility, and is suitable for a variety of applications. It is available in three different packages and a wide range of standard inductance values. Additionally, its efficient design and low winding resistance make it an excellent choice for high-current applications. The SPD127R-273M is an ideal component for board-level designs, and its performance is consistent and dependable over the entire operating temperature range.
