A fixed inductor is a passive device which stores electrical energy in the form of magnetic energy, and then dissipates this energy as an electric current in a coil. The most common type of fixed inductor is a coil of wire wrapped around a ferromagnetic core. Fixed inductors are used in a variety of applications, from electronics with capacitors in circuits for frequency control and impedance matching, to regulated power supplies and AC generators. In this article we will be looking at the PM1608S-222M fixed inductor, its applications and working principle.

The PM1608S-222M is an advanced aluminum-shield wafer type fixed inductor with high saturation current. The key features of this fixed inductor include a wide inductance range of 47 to 220mH, maximum operating temperature of up to 125°C, and a current rating of up to 14.9A. This makes it ideal for use in high-power, low-frequency applications such as switching power supplies, regulators, and AC generators. It also provides superior EMI reduction compared to traditional wirewound inductors, as it is shielded by a built-in proprietary electroplated aluminum shield.

The working principle of a fixed inductor is that electric current flowing in one direction through its windings generates a magnetic field that stores energy in a core material. When the current reverses direction, this stored energy is released back into the windings as electric current in the opposite direction. This cycle is continuously repeated, allowing the fixed inductor to provide a steady, low-level current as long as the electrical circuit is completed.

PM1608S-222M fixed inductors are ideal for use in DC-to-DC converters, automotive power supplies, and vibration motors. They are also useful for controlling resonant frequencies in RF circuits, EMI reduction, audio circuits, and general vibration control. In DC-to-DC converters, these inductors are used to increase the output power, improve efficiency, and provide voltage regulation. In automotive power supplies, they help reduce line disturbances and improve the reliability of onboard systems such as solenoids, starters, and alternators. The PM1608S-222M is also well-suited for use in motor drives and high-noise vibrators, as it provides superior EMI reduction compared to other types of fixed inductors.

The PM1608S-222M fixed inductor uses a specific construction and design to achieve its high efficiency and reliable performance. Its windings are made from an advanced polymeric material with a special dielectric design that dissipates power loss. The ferromagnetic core, which is the heart of the inductor, is composed of several layers that provide extremely low loss and excellent thermal characteristics. This core is then wrapped with a conductive shield that provides superior protection from interference. Last, a series of three-dimensional slots in the shield allows for a reduction in size and an effective way to dissipate heat buildup.

In conclusion, the PM1608S-222M fixed inductor is a reliable and efficient device for use in a variety of applications. It can be used in DC-to-DC converters, automotive power supplies, motor drives, vibration motors, and general vibration control. It offers superior EMI reduction compared to traditional wirewound inductors, as well as a durable construction and low power loss. The PM1608S-222M is an excellent choice for those looking for an efficient and reliable fixed inductor for their applications.
