Fixed inductors are electric components used to store energy in a magnetic field. The UP2SC-331-R is a high value, low ESL and ESR inductor designed for use within a broad range of applications including power supply, inverter, dc-dc converters, and other types of power related products.

The UP2SC-331-R exhibits ideal balance of energy density, stability and power density and is well suited for switching power supply, resonant converters, and other sophisticated power conversion circuits. It boasts a wide range of electrically significant parameters, such as winding resistance, self-resonance frequency, DCR, current carrying capability, efficiency and size. As a result, the UP2SC-331-R can be used as a reliable yet cost-effective solution for various power delivery applications.

The working principle of the UP2SC-331-R is based on Faraday\'s and Lenz\'s laws, which tell us that a current through a wire creates a magnetic field and a changing magnetic field creates a current. In a fixed inductor, the core creates a magnetic field when a current is passed through the windings. This magnetic field stores energy, and when the current is stopped, this energy is released back into the circuit.

Fixed inductors are used in a variety of applications. In power-supply design, they are often used to filter high-frequency noise and regulate the output current. They are also used in resonant converters, which are employed in power supplies and boost/buck converters for efficient power delivery. Fixed inductors are also used in antenna tuning, motor drive circuits, and radio frequency interference (RFI) suppression.

The UP2SC-331-R\'s construction is optimized to provide maximum efficiency and improved power delivery. It comprises two layers of windings, each one wound around a core of ferrite beads. The windings are wound in reverse directions so that the magnetic fields created cancel each other out and the inductance remains constant. The design boosts energy efficiency and reduces the leakage inductance.

The UP2SC-331-R is an excellent choice for a wide range of power supply applications, including switch mode power supplies, resonant converters, and dc-dc converters. This specific fixed inductor design is made for reliable operation with low inherent losses and high Q factors, which in turn helps to maintain stable performance and allows for reduced system size and cost. It also offers excellent efficiency and satisfies rigorous safety standards.
