CDR6D28MNNP-120NC Fixed Inductor OverviewFixed inductors, also known as inductors, are common electrical components whose primary purpose is to add inductance to a circuit. The CDR6D28MNNP-120NC is a specific type of fixed inductor, and understanding its application field and working principle can be essential for designing efficient circuits.Application FieldThe CDR6D28MNNP-120NC is mainly used in power line filtering and elimination of transverse noise. As such, it is ideal for high-frequency applications requiring impedance conversion, such as radio frequency signal transmitting and receiving circuits, and for eliminating switching noise in switching power supplies. It is usually installed on the signal line or power line to reduce waveform distortion and improve signal amplification efficiency.Physical DescriptionThe CDR6D28MNNP-120NC is a wire-wound type of fixed inductor. Each component is cylindrical and measures 0.6 inches in diameter, with the body and leads finished in a black epoxy. The lead material is copper and is suitable for soldering, with a spacing of 0.094 inches. This inductor has an inductance of 3.3mH to 6.8mH, and a rated current of 120mA.Working PrincipleThe CDR6D28MNNP-120NC works by producing an opposing magnetic field around it when current passes through it. The opposing magnetic field induces a counter-EMF, which is proportional to the rate of change of the current and opposes the applied current. This provides capacitive reactance, which acts as a filter and can achieve the effects of short-circuit attenuation or considerable impedance conversion.In addition, the inductance and self-resonance frequency of the CDR6D28MNNP-120NC plays an important role in the filter. The self-resonance frequency is the frequency at which the inductance of the device drops to zero, and is determined by the capacitance between the coil and the component body. At frequencies above this self-resonance frequency, the CDR6D28MNNP-120NC will be ineffective in filtering applications.ConclusionThe CDR6D28MNNP-120NC is a type of fixed inductor, commonly used in power line filtering and noise elimination. As a cylindrical, wire-wound component, it has an inductance of 3.3mH to 6.8mH, and a rated current of 120mA. It works by producing an opposing magnetic field, inducing a counter-EMF which can reduce waveform distortion and improve signal amplification, and its self-resonance frequency dictates how effective its filtering will be. Knowing the application field and working principle of the CDR6D28MNNP-120NC is important for the efficient design of circuits.
