Fixed inductors are widely used in electronic circuits, especially when the current running through the circuit needs to be held constant over relatively long periods of time. The 2020R-16J is a high frequency, low inductance, fixed inductor specifically designed for use in cellular applications. This inductor is capable of handling up to 10A for up to 16V, making it well-suited for most cell phone applications.

The 2020R-16J has several external features that make it suitable for use in cellular applications. It has a low equivalent series resistance (ESR), enabling it to better regulate current over extended periods. It is also resistant to self-discharge, meaning the current remains constant even when external influences, such as high temperature, cause the inductor to initially discharge.

Internally, the 2020R-16J consists of a cylindrical, ferrite coil enclosed in a plastic case with two wires emerging from either end. The case contains a ferrite core, which helps keep the inductance and ESR low. The core also has a low profile, allowing it to fit into most cellular devices easily without taking up too much space.

The core is also designed to provide minimal contact resistance, which is the resistance encountered when two conductors are in close proximity to each other. This helps the 2020R-16J perform more efficiently and with less distortion, as the contact resistance can act like a barrier, reducing the power output of the inductor.

The inductance of the 2020R-16J is approximately 1.22uh, and the current rating is roughly 10A for up to 16V. The device has a temperature coefficient of -3mohm/°C, meaning that it can effectively manage the heat generated by the device, keeping the current relatively constant. It is also resistant to temperature extremes and has a high degree of reliability.

The working principle of the 2020R-16J is relatively simple. When a current is introduced into the core, a magnetic field is generated. This magnetic field induces an EMF in the core, which is then converted into electrical energy. As the current rises in the core, the Coil will become increasingly resistant to the applied voltage, leading to the regulation of the current through the, thus demonstrating the inductor’s working principle.

In conclusion, the 2020R-16J is a high-quality, low inductance, fixed inductor designed specifically for use in cellular applications. With its low-profile, low ESR, and minimal contact resistance, the 2020R-16J is one of the most reliable fixed inductors currently available. It is capable of handling up to 10A for up to 16V, and its temperature coefficient ensures that it can manage the heat generated by the device while keeping the current relatively constant. Its working principle is based on the principle of electromagnetic induction, whereby a changing current induces an EMF in the core which is then converted into electrical energy.
