It is designed for use in power applications where high-current density, robustness, and high-temperature performance are needed. The inductor is made using advanced winding technology and is constructed with a low-profile form factor to save space in the DC-DC converter.The IDCP2218ER470M has a maximum inductance of 2.2nH, a minimum inductance of 1.8nH, and a DC resistance of 0.470mOhm. It has an inductance tolerance of ±5%, as well as a ±20% tolerance on saturation current. The inductor has a tolerance of ±2.5°C on its operational temperature range. In addition, the IDCP2218ER470M is designed to handle peak current up to 18.8A.

Application Field of IDCP2218ER470M

The IDCP2218ER470M is designed for use in DC-DC converters, such as those used in notebook computers, LCD monitors, and cellular phones. The inductor has a high-temperature performance that enables it to withstand harsh environmental conditions, making it a reliable choice for these electronics. Furthermore, its small form factor allows for easy integration into the limited space that these devices offer. The IDCP2218ER470M can also be used in other power applications where low-noise, low-loss, and high-energy efficiency are desired. This includes automotive and industrial power systems, as well as efficient lighting and luminaire applications. The inductor’s robust design is suitable for these harsh environments and ensures stability and performance.

Working Principle of IDCP2218ER470M

The IDCP2218ER470M is a fixed inductor solution that works by using the Faraday’s law of induction. This law states that when a varying electric current passes through a coil, a varying magnetic flux is created within the coil. This varying magnetic flux induces an emf (electromotive force) in the coil, which opposes the change in the electric current.The IDCP2218ER470M is made using advanced winding technology, which helps to form the coil in such a way that the varying magnetic flux is generated by the current passing through. The varying magnetic flux induces the emf within the coil, which limits the current that passes through the inductor. This helps to create a filter or buffer between the DC-DC converter’s input and output, which reduces noise and ensures efficient energy transfer.

Conclusion

The IDCP2218ER470M is a type of fixed inductor solution designed for use in power applications where high-current density, robustness, and high-temperature performance are needed. The inductor works by using the Faraday’s law of induction, which states that a varying electric current passing through a coil creates a varying magnetic flux, inducing an emf in the coil and limiting the current that passes through the inductor. The IDCP2218ER470M has a range of applications, including DC-DC converters, industrial and automotive power systems, and lighting and luminaire applications.
