Fixed inductors are components used in many electronic circuits and devices. They are passive devices that store energy in the form of a magnetic field created by an electrical current. The SPM4015T-3R3M-CA is a fixed inductor device that offers a wide variety of benefits for system and design engineers. This application note provides an overview of the SPM4015T-3R3M-CA, including its application field, working principle, and other features.

Application Field

The SPM4015T-3R3M-CA is a fixed inductor designed primarily for use in switching power supplies, battery management systems, and other high frequency circuits that require stable power delivery and precise current control. The device’s low equivalent series resistance (ESR) ensures enhanced performance, while its low profile, thin package is ideal for space-restricted projects. This inductor is also suitable for board-level DC-DC switching circuits and other applications that require inductance in the range of 0.45µH to 1.5µH.

Working Principle

The SPM4015T-3R3M-CA is a surface-mount, shielded inductor that utilizes a powdered iron core as its magnetic field medium. When an electrical current passes through the inductor, its metal windings generate a magnetic field that subsequently induces an opposing electrical field inside the core. This operational characteristic increases the inductor\'s resistance to higher frequency signals. In other words, the higher the frequency of the electrical current, the greater the inductance of the device.

The inductance of the SPM4015T-3R3M-CA remains constant as operating conditions change. This reliable operational characteristic ensures that the power delivered to the load remains consistent and accurate over its full operating range. Another key feature of this inductor is its ability to dissipate heat quickly, which further enhances the device\'s performance. The wide temperature range of this device, from -40°C to 125°C, makes it an excellent choice for industrial and commercial applications.

Other Features

The SPM4015T-3R3M-CA is RoHS-compliant. It also offers an impressive level of surge protection, withstanding up to 36A of current in steady state operations and 100A of current in transients. The inductor\'s high-temperature stability also ensures superior performance in all environments. The device has a corrosion-resistant shell with an encapsulated core; and its mounting holes are compatible with a variety of substrates, including metal, PCBs, and ceramic materials.

The SPM4015T-3R3M-CA is a versatile fixed inductor designed for high-frequency operations and offers a wide range of features for applications in power supplies, battery chargers, and other electronic equipment. Its low profile, low equivalent series resistance, and wide temperature range make it an excellent choice for many design projects.
