Fixed Inductors

Inductors, sometimes referred to as coils or chokes, are devices consisting of a wire, a core, and an electrical connection. They are used in a variety of applications to store energy in the form of a magnetic field and to help regulate the current flow in a circuit. Fixed inductors are passive components of electrical circuits that are designed for a single purpose and have a fixed inductance rating. One such fixed inductor is the HCM1A0703-1R2-R, a thick film chip inductor with a typical inductance of 1.2 μH.

Application Field of HCM1A0703-1R2-R

The HCM1A0703-1R2-R is designed for use in a variety of digital and analog circuit applications. It is particularly well suited for RF applications. It provides an excellent combination of low DC resistance, high self-resonance, and low Q factor. Its high voltage tolerance and outstanding inductance stability makes it suitable for a wide range of signal-switching and timing applications, including LED drivers, audio amplifiers, and switching power supplies. It is also widely used in medical equipment, consumer electronics, and automotive electronics.

Working Principle of HCM1A0703-1R2-R

The working principle of an inductor is based on Faraday’s law of induction. When a current flows through an inductor, a magnetic field is created. This magnetic field in turn induces a voltage in the inductor and this voltage opposes the initial current, causing it to decrease. The magnitude of the induced voltage is inversely proportional to the rate of change of the current. In other words, as the rate of change of the current increases, the induced voltage decreases.The construction of the HCM1A0703-1R2-R allows it to store more energy in the form of a magnetic field than other fixed inductors of the same size. This is due to its high self-resonance, high frequency response, and low DC resistance. Its extremely low Q factor ensures excellent inductance stability over a wide range of frequencies.

Conclusion

The HCM1A0703-1R2-R is a high-performance fixed inductor that is designed for use in a variety of digital and analog circuit applications. Its high voltage tolerance and outstanding inductance stability make it suitable for signal-switching and timing applications. Its construction allows it to store more energy in the form of a magnetic field than other fixed inductors of the same size. Its high self-resonance, high frequency response, and low DC resistance make it an excellent choice for RF applications.
