Fixed Inductors: LHF15BB271K application field and working principle

Fixed inductors are electronic components that are designed to create a constant inductance in an electrical circuit, regardless of varying currents and voltages. The LHF15BB271K fixed inductor is a type of magnetic coil unit used to store and release electrical energy, blocking DC current and passing AC current, and spawning the production of voltages through electromagnetic induction.

The LHF15BB271K is characterized by an operating temperature range from -40°C to +125°C, rated inductance of 0.271uH ±20%, a current rating of 1.2A, Q value of 79.2 @0Adc and SRF of 8.5GHz. These properties make the device suitable for various applications, such as integrating power supplies, filter circuits consisting of power oscillators, amplifiers, and radio blockers, automotive supplies, especially in the starter system, as well as in car audio equipment.

The working principle behind this product is that, at low frequencies, the inductor works like a resistor. As the frequency increases, the inductive reactance of this component increases, allowing AC signals to pass more easily through the circuit. Since the current and voltage are out of phase, an inductor can help absorb, store and release energy. When a voltage is applied to its terminals, a time lag occurs for current flow, allowing the inductor to store energy in a magnetic field. When the current is removed, the magnetic field induced by the current is reversed, thus generating a current of opposite polarity, and releasing energy.

In conclusion, the LHF15BB271K fixed inductor is a great choice for a variety of electronic activities, and is specially designed to create a stable inductance in an electrical circuit. Both its temperature range and current rating make this device perfect for several scenarios, such as power supply integration, filter circuit and amplifiers application, as well as audio equipment, owing to its steady current and voltage characteristics.
