Fixed inductors are widely used in electronics circuits, particularly in the circuits of direct current power supply and digital circuits. ISC1812ER121K, a fixed inductor produced by ISC Electronic, is one of the most popular inductors. It can be used in many applications as a “coil” or a “stabilizer”.

The ISC1812ER121K is a 120uH wind-type inductor, rated for 1A current. The product size is 18 x 12mm, which is very compact and suitable for installations in tight spaces. The inductor also has a high-temperature resin case, which helps to protect the internal components from heat and moisture. Additionally, the inductor is UL approved and RoHS compliant.

ISC1812ER121K can be applied in a wide variety of applications, including power supplies, LED lighting, switching power supplies, and digital circuits. It can also be used for filtering, signal conditioning, and for protection against noise interference.

The working principle of ISC1812ER121K is based on the basic law of induction. When a current flows through the inductor, a magnetic field is generated which induces a voltage around the inductor. This voltage opposes the current, decreasing the current flow. The larger the current through the inductor, the larger the opposition and the greater the reduction in flow.

The ISC1812ER121K also has a self-healing property. This means that when the inductor is subjected to a short circuit, the current flows through the coil and the induced voltage is high enough to break down the insulation of the coil, which clears the short circuit. After the short circuit is cleared, the coil can be used again without the need for replacement.

In summary, ISC1812ER121K is a 120uH wind-type inductor with a 1A current rating. It has a compact size of 18 x 12 mm, high-temperature resin case, UL approval, and RoHS compliance. It has a wide range of application, such as power supplies, LED lighting, switching power supplies, and digital circuits. Its working principle is based on the law of induction, and it has a self-healing property.
