ER1641-393KM

Fixed inductors are electronic components that store energy in the form of a magnetic field. They typically consist of a coil of conducting wire wrapped around a magnetic core. The ER1641-393KM is an example of a high-quality fixed inductor. This part is primarily used in home theaters, car audio systems, and computer audio systems for audio filtering, signal conditioning, and noise cancellation.

The ER1641-393KM offers excellent power handling and high saturation current ratings. It offers a high self-resonance frequency of over 800 MHz, allowing for use in high-frequency applications. It has an operating temperature range from -40 to +125 °C and a high thermal shock rate, making it suitable for outdoor as well as rugged environments.

The operating principle of a fixed inductor is based on Faraday\'s law of induction. According to this law, when a current is passed through a coil, a magnetic field is generated. This magnetic field then induces a voltage in an adjacent coil. The amount of voltage induced depends on the rate of change of current in the primary coil, the number of coils in the primary and secondary coil, and the value of flux in the core.

ER1641-393KM fixed inductors have a permeance value of 60uH, which makes them suitable for inductive applications. The internal construction of the part consists of a laminated copper coil that is wound around a ferrite core. This part is tightly wound to ensure maximum inductance value and the highest level of performance. It also has a rugged design that can withstand up to 10,000 mechanical cycles.

The ER1641-393KM is an incredibly versatile part that is suitable for a wide range of applications. It is ideal for audio filtering, signal conditioning, and noise cancellation applications in home theaters, car audio systems, computer audio systems, and any other electronic system that requires high current and high frequency performance.
