Fixed inductors are found in almost every electrical circuit, from simple analogue circuits to sophisticated embedded systems. The SLF7055T-1R5N4R0-3PF is a fixed inductor from TDK Corporation that is meant to meet a variety of needs in different types of electrical applications. It is a low-profile multilayer inductor ideal for mobile applications, DC-DC converters, power management, and battery-operated equipment.

The SLF7055T-1R5N4R0-3PF has a rated inductance of 1.5 uH with a tolerance of 0.3 uH and an Operating Temperature range from -25°C to +85°C. It is a small device measuring just 4.5 x 3.8 x 3.2 mm and comes in a surface-mounting type T package. Its rated current ranges from 0.4A to 1.2A often determined by the system. Higher current ratings are possible with this inductor but may also be limited by other components of the system.

The construction of the SLF7055T-1R5N4R0-3PF consists of a magnetically shielded core that is made up of multiple layers of metallic material. The size and number of layers depend on the desired inductance value of the component. Depending on the desired results, as many as 10 layers may be wound in series with a magnetic shield around it. The core is then protected by an encapsulated epoxy resin which acts as a self-sustaining component providing stability and insulation.

The working principle behind any fixed inductor is based on Faraday\'s law. When a magnetic field is applied to the core, a small voltage is generated due to the inductance of the core. This is followed by a change in the inductance of the core, thereby altering the voltage induced, which creates a feedback loop. As the magnetic field increases, the core inductance also increases leading to a higher feedback voltage.

The amount of voltage feedback generated in the SLF7055T-1R5N4R0-3PF is closely related to its capacitance. At low frequencies, the self-inductance of the core will be slightly higher than its capacitance, while at high frequencies this relationship will reverse. This principle makes this component suitable for many applications such as RF circuits, dc-dc converters, power amplifiers, voltage regulators, and AC stage circuits.

The SLF7055T-1R5N4R0-3PF is a reliable, small-size inductor that is ideal for a variety of applications. Its high operating temperature range and low profile make it suitable for mobile applications as well as small form factor embedded systems. With its ability to maintain a stable inductance over a wide frequency range, this versatile component provides excellent performance in a range of applications.
