Fixed inductors are energy storage components that store energy in the form of an electromagnetic field when an electrical current passes through them. Among the many different types of fixed inductors available, the CDRH127/LDNP-101M series from Sumida-America Components (SAC) offers the greatest variety of options. This series is designed for various applications, including voltage leveling, automotive voltage power-supply voltage attenuation, frequency compensation, and RF matching.

The CDRH127/LDNP-101M series is available in seven standard size packages, including a smaller chip geometry that fits into small, space-constrained devices. These inductors feature a variety of inductance values ranging from 0.3 μH to 33 μH, as well as maximum current ratings ranging from 65 mA to 4A. They also have relatively high self-resonance frequencies between 400 kHz and 40 MHz, the highest being around 800 kHz.

The main feature of the CDRH127/LDNP-101M series is their ability to provide a high level of inductance stability over a wide range of temperatures. This is achieved through a combination of ferrite core construction and winding techniques. The ferrite core material used is designed to have low losses at higher frequencies, ensuring that the inductor can provide a consistent value of inductance as temperatures and current rise. The winding technique used here helps reduce parasitic capacitance, resulting in higher self-resonance frequencies and lower noise levels.

The most typical CDRH127/LDNP-101M application fields are related to frequency compensation. The inductor’s high self-resonant frequency together with its high currentRating enable it to be used for compensation in high-showever most diyfrequency circuits. Examples include high-speed power converter circuits and communications networks which require stable and low-loss operation. The inductors can also be used for voltage levelling, attenuation of power-supply voltages and RF matching circuit applications.

Due to its low profile and low Insertion loss, CDRH127/LDNP-101MC can also be used in mobile devices such as smartphones or tablet PCs. It provides a superior performance for forming filters in these types of products helping reduce the radio emission.

The working principle of the CDRH127/LDNP-101M is relatively simple. An electrical current passing through the inductor’s windings generates a magnetic field that stores energy. This energy is then released when the current is reversed. The magnitude of the magnetic field is proportional to the number of turns in the inductor’s windings, which in turn determines the inductor’s value. The stored energy is dissipated as heat as the current passes through the inductor, resulting in a small amount of power loss.

In conclusion, the CDRH127/LDNP-101M is a great choice for applications that require a high level of inductance stability over a wide range of temperatures. It is available in seven standard product packages and offers a wide range of inductance values and current ratings. It is especially well suited for frequency compensation, voltage leveling, attenuation of power supply voltages, and RF matching. It can also be used for mobile devices such as smartphones or tablets. The working principle is simple, with an electrical current passing through the windings generating a magnetic field that stores energy and then releases it when reversed.
