The 1812R-683H is one of the most common fixed inductors in the market. It is designed for circuit applications where current levels are relatively constant, such as in embedded memory circuits. The 1812R-683H is a high-performance inductor, offering superior current delivery with its low-loss winding technology. Its low DC resistance and minimal current ripple ensure consistent operation in circuits.

The 1812R-683H has a high inductance rating, making it an ideal choice for impedance matching or higher frequency EMI suppression applications, since it can effectively provide tight EMI filtering with minimal physical size.

The 1812R-683H is constructed with a loop winding made of high quality copper. The core is made of ferrite material; other core options, such as iron powder, are also available. The inductor can handle up to 6.8A of current, and its inductance range is from 10uH to 220uH.

The 1812R-683H is designed for use in the SMT reflow process. It features an epoxy coating that prevents component damage resulting from exposure to high temperatures. The epoxy coating also provides protection from moisture and helps prolong the life of the inductor.

The working principle of the 1812R-683H is based on Faraday’s law, which states that the rate of change of magnetic flux through a circuit induces an electromotive force. The coil in the 1812R-683H is designed to convert electrical energy into magnetic energy, and when the current through the inductor is changed, the magnetic flux linked to it also changes, inducing a voltage in the coil which opposes the change in current.

The 1812R-683H is typically used in applications such as DC/DC converters, power supplies, portable electronic devices, and consumer electronics. Its high inductance rating and low DC resistance ensure efficient power delivery with minimal energy waste. Its epoxy coating helps improve durability and prevent environmental damage, making the 1812R-683H an ideal choice for many applications.
