Fixed Inductors

A fixed inductor is an electronic device designed to store energy in the form of a magnetic field. The 2512R-682J fixed inductor is a surface mount device that is widely used in a variety of applications. This device is especially useful in high density applications such as audio and digital circuits.

Application Field

The 2512R-682J fixed inductor is mainly used in low-voltage analog, digital and mixed-mode circuit designs such as switching power supplies, audio filters, clock and data recovery circuits, and signal separators. This device is also used in radio receiver tuning circuits, high-frequency switching amplifiers, and piezoelectric actuators.

Working Principle

The 2512R-682J fixed inductor works on the principle of inducing magnetic fields from placed conductors. In general, when DC current passes through a conducting coil, a time-varying magnetic field is generated that is proportional to the applied current. This magnetic field then extends outwards from the centre of the coil in concentric circles. This magnetic field then induces voltage in any additional conductors that are placed within this field, thereby allowing the stored energy to be released in the form of voltage. The inductance of the device is measured in henries, and typically ranges from 0.1µH to 10mH.

The 2512R-682J has the advantage of being an efficient, reliable, and low-cost option for inductor applications. It has an operating temperature range of -55°C to +125°C, and is available in various package sizes depending on the application. The inductor has a high Q value, meaning that it can store most of the energy that is being applied to it, making it an ideal choice for applications that require high efficiency and low-radiated emissions.
