Fixed Inductors

Inductors are passive electronic components that are used in almost every electronic circuit. Their main function is to store and release electrical energy. A fixed inductor, such as the CR75-2R2MC, works by inducting a magnetic field in its windings upon the application of an electrical current. This magnetic field, in turn, creates an opposing force, which induces a back EMF, or voltage, in the windings. This voltage can then be harnessed and used in a variety of applications. The CR75-2R2MC is a standard two-layer, radial fixed inductor. It is one of the most commonly used fixed inductors due to its low cost, high reliability, and general purpose suitability. It is used in a wide variety of applications, from high-frequency filtering and signal routing to DC-to-AC conversion and noise cancellation.The CR75-2R2MC is composed of two distinct parts – a core and windings. The core is typically made of ferrite or molybdenum permalloy and serves as the medium for the inductor\'s magnetic field. This core is typically wrapped in a spool of insulated copper wire which forms the inductor\'s windings. These windings are wound in a spiral configuration, which helps reduce the inductor\'s DC resistance and allows it to generate a higher inductance value. The CR75-2R2MC implements a basic Ferrimagnetic or traditional high-frequency inductor circuit. The main difference between the CR75-2R2MC and other Ferrimagnetic inductors is the shape and number of its windings. This particular model has two windings which helps to increase the inductance value and reduce its resistance.In operation, the CR75-2R2MC inductor works by generating an alternating magnetic field in its windings upon the application of an electrical current. The changing magnetic field induces a back EMF in the windings which produces a voltage in the circuit. This voltage can then be used to regulate or shape the current passing through the circuit. Additionally, the CR75-2R2MC’s high frequency response makes it suitable for a variety of high frequency-filtering applications.The most common application of the CR75-2R2MC is as a low-pass filter or audio crossover. A low-pass filter is used to remove unwanted high-frequency components from a signal. The CR75-2R2MC’s low frequency response and high inductance make it an ideal choice for this application. The CR75-2R2MC is also commonly used as a signal filter in audio systems as well as to provide DC-to-AC conversion and noise cancellation.Overall, the CR75-2R2MC is a versatile fixed inductor that is used in a variety of applications, from signal filtering and high frequency response to DC-to-AC conversion and noise cancellation. Its low cost and high reliability make it one of the most popular fixed inductors available.
