Fixed inductors are electrical units that store energy through an electromagnetic field. They come in a variety of forms, sizes and constructions, all of which have the same basic function. A fixed inductor is essentially a coil of wire that opposes a change in electric current. When current passes through the coil, a electromagnetic field is generated, which stores energy. This article will discuss the SPD73R-683M and its applications and working principles.

The SPD73R-683M is a small, surface-mount type inductor with a rated inductance of 0.680µH and a wide range of current ratings from 0.017 to 0.455A. It is designed for use in applications requiring low profile components such as low-voltage, low-power electronic circuits. The fixed inductor utilizes a moulded plastic construction, which makes it highly compact and lightweight, making it ideal for applications where space is at a premium.

The SPD73R-683M has a maximum DC resistance of 0.0086Ω and an operating temperature range of -40 ˚C to +105˚C. It is available in a variety of package types such as 0805, 1206 and 1210, allowing users to select the size that best suits their needs. The inductor also has a wide frequency range of up to 20MHz, making it suitable for a variety of switching, sensing and DC to DC applications.

The working principle of a fixed inductor is based on the law of induction. This states that a changing magnetic field induces an electric field, and vice versa. When a current passes through a fixed inductor, it creates a magnetic field around it. This magnetic field then induces a voltage in the wire which opposes the current. This is known as the inductive reactance, and it can be used to provide a steady current or to filter out high frequency signals.

The SPD73R-683M can be used in a variety of applications including filters, radio frequency interference suppression, motor speed control, switching power supplies and power factor correction. It can also be used as part of a resonant tank circuit for oscillators, audio amplifiers and other frequency-dependent devices.

In summary, the SPD73R-683M is a fixed inductor with a wide range of current ratings and a wide frequency range. It has a moulded plastic construction which makes it highly compact and lightweight, making it ideal for applications where space is at a premium. The working principle of a fixed inductor is based on the law of induction, and it can be used in a variety of applications including filters, radio frequency interference suppression, motor speed control, switching power supplies and power factor correction.
