Fixed Inductors are passive electrical components, which are commonly used in various applications, such as filtering, coupling, decoupling, impedance matching, and others. The CDR125-391MC is a type of Fixed Inductor manufactured by Coilcraft, Inc. It is commonly used in various applications, including high-efficiency power supplies, DC/DC converters, audio amplifiers, and signal conditioning circuits.
The CDR125-391MC features an inductance value of 0.391μH, a maximum DC current rating of 6.5A, and a saturation current of 12.9A. It also has a maximum DC resistance of 33 mΩ, a maximum AC resistance of 45 mΩ, and a self-resonant frequency of 17.0 MHz. The device is designed to withstand a temperature range of -40°C to +125°C. It is also capable of withstanding a maximum operating voltage of 25V.
The primary function of Fixed Inductors is to store energy in an electromagnetic field and then release it when necessary. This energy is typically released in the form of current, or by connecting two inductors together, such as in an LC circuit. The CDR125-391MC utilizes this function to regulate the amount of current that passes through its inductive coil. Its inductance value affects the amount of current that will pass through the coil, and the number of turns on the coil affects its AC resistance.
In a DC/DC converter, for example, the CDR125-391MC can be used to regulate the current in the circuit. The device acts as a conductor, allowing certain levels of current to pass through the coil, while also limiting the total amount of electricity that can flow through the coil. This ensures that the converter is able to operate without exceeding its rated current levels. The CDR125-391MC is also capable of reducing the amount of noise present in AC power lines by limiting the amount of current that passes through it.
Additionally, the CDR125-391MC can be used to filter unwanted frequencies from circuits. This is done by winding the inductive coils to have certain resonant frequencies, which helps to prevent the transmission of certain frequencies. This can be useful for audio amplifiers, as it can help to reduce the amount of noise present in an audio signal.
Overall, the CDR125-391MC is a highly versatile Fixed Inductor that can be used for a variety of applications. Its high inductance value, low DC resistance, and high voltage rating make it an ideal choice for use in high-efficiency power supplies, DC/DC converters, audio amplifiers, and signal conditioning circuits. Furthermore, its ability to reduce noise in AC power lines and filter unwanted frequencies makes it an invaluable tool in many different circuits.
