CDH74NP-390KC

Fixed Inductors are key components in many electronic applications. The CDH74NP-390KC is an epoxy-coated toroid inductor, offering higher inductance values than traditional wire-wound inductors. This type of component is used primarily for applications that require gradual frequency switching, such as power supplies, energy-saving equipment and precision current measurement.

The CDH74NP-390KC inductor features a low watt core that is capable of dissipating heat efficiently, and it also offers high impedance properties with a resulting inductance value of 0.390mH ±20%. This makes it an ideal choice for applications that require high stability and accuracy, such as signal filtering and voltage regulation.

The core of the CDH74NP-390KC inductor is made from a ferrite material, which is then sealed in an anti-moisture epoxy coating. This combination allows the inductor to operate at higher temperatures and lower voltage drops than traditional inductors. Additionally, the epoxy coating also helps protect against shorting and arcing that can occur with wire-wound inductors.

The working principle of this inductor is simple. When current flows through the conductive windings of the inductor’s core, it creates a magnetic field. This field interacts with the core and induces an opposing field, thus creating a dynamic resistance. This resistance is known as inductance, which is measured in henrys.

The CDH74NP-390KC inductor is used primarily in power management applications where high inductance values are needed. The inductor can also be used to improve the performance and efficiency of energy-saving devices, such as organic light emitting diode (OLED) displays, light bulbs and higher voltage AC circuits.

The CDH74NP-390KC inductor is also well suited for tuning and filtering applications. It has low loss characteristics and the epoxy coating helps keep the inductor’s resistance and inductance values constant even at high frequencies. This makes it ideal for applications such as radio frequency (RF) amplifiers, transmitters and receivers, as well as switching systems and power converters.

In summary, the CDH74NP-390KC fixed inductor is an extremely durable and efficient component for applications that require high stability and accuracy. Its epoxy coating offers superior protection against shorts and arcing, and it is capable of dissipating heat very efficiently due to its low watt core. The inductor has a wide range of applications, from radio frequency to power management, and its high inductance values make it suitable for tuning and filtering tasks.
