1812R-274G

Fixed inductors, which are sometimes referred to as "chokes" or "coils," are electrical components that provide a specific amount of inductance (measured in Henrys) in a circuit. The 1812R-274G inductor is no exception, as it is a radial, leaded, fixed inductor featuring a flat-packed package with a copper lead and a black lacquered finish. However, one key distinguishing feature of this particular component is its low RDC value of 147mΩ, which makes it particularly well-suited for power conversion applications.

Fixed inductors are used in a variety of applications, but the 1812R-274G is most commonly used in DC/DC power converters, voltage regulators, power supplies, lighting, welding, and industrial motor drive circuits. It has an acceptable temperature range of -40 to 85 °C, which makes it suitable for a wide range of environments. Additionally, the component comes with a tape-and-reel size of 1000 pieces per reel, making it easy to transport and handle.

The 1812R-274G fixed inductor works through the principles of electromagnetic induction. In essence, when an electric current is passed through the component, it creates an associated magnetic field which then induces an electromotive force in the components connected in parallel. As the current increases, so does the corresponding magnetic field, both of which induce an increase in the electromotive force. The magnetic flux generated by the component is maintained due to the fact that there is a self-induction of the coils, which results in an increased amount of electromotive force.

The 1812R-274G also offers superior noise suppression and EMI attenuation due to its unique construction. This is a desirable feature in applications such as railways, mobile phones, and other electronic devices which require low levels of interference. Additionally, the component has excellent self-resonance characteristics, making it suitable for switching power supplies, motor drives, and other high-frequency circuits. Its high self-resonance frequency (7.5MHz) also helps reduce the amount of signal distortion, ensuring that signals remain stable and free from interference.

The 1812R-274G fixed inductor is an incredibly versatile component, offering numerous advantages including low RDC values, high-frequency characteristics, and noise suppression capabilities. It is ideal for use in applications such as DC/DC power converters, voltage regulators, power supplies, lighting, welding, and industrial motor drive circuits, and its temperature range of -40 to 85 °C makes it suitable for a wide range of environments. With its tape-and-reel size of 1000 pieces per reel, it is easy to transport and handle, making it a highly desirable component for many electronic applications.
