Fixed inductors are electrical components used to maintain a steady current through a coil or other conductor. They come in various shapes and sizes, and their purpose is to store, release, and regulate electrical energy. In industrial applications, these components usually take the form of a "squirrel cage," which consists of an insulated wire wrapped around a metal bar. The resulting inductor can be used in a wide range of applications, including radio receivers, amplifiers, and power supplies. The SPD74R-352M Fixed Inductor by Phoenix Contact is an example of such an inductor. The device has a rated power of 30 Watts, an inductance of 2.20µH ± 20% at 100 kHz, and a parallel capacitance of 5.33pF ± 20%. These impressive specs make the device well-suited for power supplies, dc-to-dc converters, and power amplifiers. They can also be used in noise suppressors and voltage-mode logic circuits.The working principle of the SPD74R-352M is similar to that of other fixed inductors. When a voltage is applied across the component, a current begins to flow in the wire. This current is resisted by the inductor, resulting in a buildup of magnetic energy in the coil of wire. This buildup resists the flow of current, acting as a kind of "gatekeeper" to regulate the amount of energy allowed through the component.In some cases, the magnetic energy held in the inductor can be harnessed to do useful work. By connecting an additional conducting coil to the inductive component, an alternating current can be drawn from the device. This current can be used to power small motors, electrical appliances, and other devices.The SPD74R-352M is designed to provide reliable performance in a variety of demanding environments. It is constructed using high-quality materials that can resist extreme temperatures, and it has a rated operating temperature of -25°C to +85°C. Additionally, the device is RoHS2 compliant, meaning it does not use any materials that pose a risk to human health or the environment.Overall, the SPD74R-352M is an ideal solution for applications that require steady output, high efficiency, and long-term reliability. It is a robust inductor that can deliver reliable performance in a wide range of temperature and voltage conditions. This makes it an ideal choice for applications such as dc-to-dc converters, noise suppressors, and voltage-mode logic circuits.
