Fixed Inductors: ER1641-124KP application field and working principle

An inductor, also known as a choke, is an electrical component that stores energy in the form of a magnetic field. It is essentially a coil of wires, usually wrapped around a ferrite or iron core, through which a current is passed to induce an electromagnetic field. Inductors are used in electronic circuits and devices for the purpose of providing electrical impedance or signal filtering.

ER1641-124KP is a type of fixed inductor which has been developed with innovative technologies for high power and high reliability applications. This inductor has the impedance value fixed at the time of manufacture – the inductance changes only slightly when current flows through it. The product is compact in size and offers a good cost performance ratio, making it suitable for applications in automotive, industrial and consumer electronics.

The basic working principle of an ER1641-124KP fixed inductor is that when current is passed through the coil, a magnetic field is generated which stores energy. This stored energy is then used to oppose any changes in the applied current. The rate at which the current changes (known as the inductor\'s time constant) is inversely proportional to its reactance, which is inversely proportional to its value. This means that the bigger the inductor, the slower the current changes.

When the ER1641-124KP inductor is used in applications, its key features make it a suitable choice. It has low DC resistance and low inductance tolerance. It has an operating temperature range of -40°C to + 125°C, excellent temperature stability and resistance to shock and vibration. It also has a coefficient of thermal expansion that is close to that of FR-4, making it easy to use in a board. In addition, it can withstand soldering temperatures of up to 260°C.

ER1641-124KP fixed inductor is widely used in various industries, especially in automotive and consumer electronics. It can be used for power supplies, power line filter circuits, feedback circuits, signal processing circuits, and in communications equipment. It is also used for switching power supplies, high-frequency radio applications, and light control circuits. Furthermore, this product is suitable for applications where high tolerances are required, since it has a coefficient of temperature expansion that is very close to that of FR-4.

In summary, the ER1641-124KP fixed inductor is a reliable and cost-effective product which can be used in a variety of applications, ranging from automotive and industrial to consumer electronics. It has an operating temperature range of -40°C to +125°C, low inductance tolerance and excellent temperature stability. It is capable of withstanding soldering temperatures up to 260°C and has a coefficient of thermal expansion close to that of FR-4. As such, it is a suitable choice for applications where high tolerances are required.
