Fixed Inductors

Inductors are passive electronic components that store electrical energy in the form of magnetic field. They are essential components in the analog circuitry of many different types of electronics such as radio, television, and audio equipment. One such type of inductor is the 0603-68NK.

Types of 0603-68NK Inductors

The 0603-68NK inductor is a fixed inductor, meaning it is not adjustable. It is designed to work within a specific frequency range and can be used in applications operating at DC, low-frequency, and high-frequency. The two main types of inductors are the through-hole and the surface-mount. The 0603-68NK is a surface-mount inductor. It is the same size as a through-hole inductor but it has two small legs that act as standoffs that allow the inductor to be mounted directly onto a circuit board and used in applications with high-density protoypes.

Electrical Properties of 0603-68NK Inductors

0603-68NK inductors are designed to handle high current loads and are typically used in switching and filtering applications. They are made up of a coil of copper wire wrapped around a non-conductive core material. This produces a high inductance value, which is measured in units of henries. The inductor has a low DC resistance, usually less than two ohms, and a self-resonant frequency (SRF) of 30MHz, meaning it is capable of operating at frequencies up to 30MHz.

Application Fields of 0603-68NK Inductors

0603-68NK inductors have a variety of applications, such as in radio transmitters and receivers, audio amplifiers, and switching power supplies. They are also commonly used in circuits that require voltage regulation or filtering. The inductor can be used alone or combined with other components such as resistors and capacitors to create filter networks.

Working Principle of 0603-68NK Inductors

The 0603-68NK inductor works by storing energy in a magnetic field generated by the coil of copper wire. When a current is applied to the inductor, a magnetic field is created in a counterclockwise direction that opposes the current flowing through the inductor. This causes the voltage across the inductor to increase. When the current is removed, the magnetic field is released and the voltage across the inductor decreases. The inductor stores energy as long as current is applied to it, and when the current is removed, it releases the stored energy.

Conclusion

0603-68NK inductors are fixed inductors, meaning they cannot be adjusted. They have high inductance values, low DC resistance, and a SRF of 30MHz. They are used in a variety of applications from radio transmitters and receivers to voltage regulation and filtering. The inductor works by storing energy in a magnetic field produced by the coil and releasing it when the current is removed.
