Fixed Inductors

An inductor is an electrical device made up of a coil of insulated wire, often around a ferromagnetic core. Its primary purpose is to store energy in the form of a magnetic field. An inductor is a passive device, meaning it consumes rather than generates electrical energy.The PM75-100K-RC fixed inductors are a type of inductor specifically designed with a precise inductance value, also known as a value-fixed inductor. This type of inductor provides a higher self-resonant frequency than discrete inductors and consumes less current than the adjustable types.The PM75-100K-RC is an ideal choice for use in regulated power supplies, digital filters and other sensitive electronic circuits requiring an inductor with fixed properties. The typical on-resistance is 30 milliohms or less. The leakage inductance is 1.1 nH or less, meaning there is minimal cross-talk interference between adjacent windings.The PM75-100K-RC fixed inductors are typically used in low-loss power supply and high-frequency filtering applications. The inductance value of this type of inductor is generally low, but their temp coefficient and saturation characteristics make them a great choice for high-frequency applications.The PM75-100K-RC fixed inductors are able to provide high quality, reliable performance in harsh environments. They are designed with high insulation resistance, low stray magnetic fields, excellent temperature stability, and minimal temperature coefficient. These attributes make them suitable for applications where performance is critical and where cost is a secondary factor.The principle working of the PM75-100K-RC fixed inductors is based on an anomaly in the behavior of current through a wire coil which is referred to as "mutual inductance". When a current runs through a wire coil, it creates a self-induced magnetic field that resists a change to the current, and this forms an inductance. This inductance acts as a filter, allowing low-frequency signals to pass while blocking higher frequency signals. Because the inductance of the PM75-100K-RC fixed inductors is preset at manufacture, it can be used to filter out a variety of unwanted electromagnetic noise from a circuit. The inductor is typically connected in series with the input power lead of a regulated power supply, or can be used in conjunction with other types of filters, such as capacitors.The PM75-100K-RC fixed inductors are also used widely as part of larger circuits. When multiple inductors are connected in series or in parallel, this can create a completely different filter characteristics and frequency response to high- or low-frequency signals.In conclusion, the PM75-100K-RC fixed inductors are designed for a variety of applications, including low-loss power supplies, high-frequency filtering applications, and other sensitive electronic circuits that require precise inductance values. The presence of self-resonance parameters makes these inductors ideal for high-frequency applications, while high insulation resistance and low stray magnetic fields mean they are suitable for use in harsh environments. As always, careful consideration should be taken when selecting the best inductor for your application.
