Fixed Inductors

Inductors, or coils, are electrical components that oppose changes in electric current. They are used to provide electrical power, filter signals, provide impedance, and in electromagnetic systems. The most common form of an inductor is a coil of wire, although other shapes are possible. Some inductors are designed to be fixed in a circuit, while others are variable.

The CDRH5D14HPNP-3R3NC is a fixed inductor manufactured by CINOTON that is designed specifically for power applications. It is a ceramic-based, shielded, surface-mount inductor with EMI and DC bias performance. The inductor has a 3.3mH inductance, a maximum current rating of 200mA, and a self-resonant frequency of up to 1MHz.

Application Fields

The CDRH5D14HPNP-3R3NC is designed for use in a variety of power applications. It can be used in switching power supplies, high-frequency ballasts, resonant converters, motor control circuits, and other applications that require a DC bias. It can also be used for EMI suppression, making it ideal in both demanding and sensitive electronic environments.

The CDRH5D14HPNP-3R3NC is also suitable for use in automotive applications, due to its wide operating temperature range. It is resistant to both thermal and electrical stress, making it a reliable choice for harsh environments.

Working Principle

Inductors rely on the principle of electromagnetic induction, which states that a current in a wire induces a magnetic field. When a wire is wound into a coil, the magnetic field lines add together, creating a stronger field. This field then acts to oppose changes in electric current, producing a back electromotive force.

This back electromotive force is what defines an inductor\'s inductance, which determines the amount of opposing force an inductor can provide. The more coils in the inductor, the more force, and therefore the higher the inductance. The CDRH5D14HPNP-3R3NC has three coils, providing higher inductance than a single-coil inductor of the same size.

The CDRH5D14HPNP-3R3NC also has a ceramic core, which provides additional magnetic field control. This type of core also increases the self-resonant frequency of the device, which defines the frequency at which it begins to decrease in inductance.

Conclusion

The CDRH5D14HPNP-3R3NC is a fixed inductor with a 3.3mH inductance, a maximum current rating of 200mA, and a self-resonant frequency of up to 1MHz. It is designed for use in a variety of power applications, including switching power supplies, high-frequency ballasts, resonant converters, and motor control circuits. It also features a ceramic core, which increases its self-resonant frequency and provides additional magnetic field control. The device is resistant to both thermal and electrical stress, making it suitable for use in automotive applications and harsh environments.
