Fixed Inductors: HKQ040239NJ-E

Inductors are a type of electrical component used to store energy in the form of a magnetic field. As current flows through the coil of wire, it generates a magnetic field that induces voltage in the same coil of wire. Fixed inductors are inductors with static parameters—they are not adjustable and cannot react to changes in current. The HKQ040239NJ-E is an example of a fixed inductor. It is a unshielded, radial-lead inductor with an operating temperature range between -55°C and +125°C. Its uses and working principle can be discussed further below.

Application Field

The HKQ040239NJ-E fixed inductor can be used in a variety of applications, including voltage regulation, power supplies, switching circuits, and telecommunication devices. It can also be used in various electronic circuits, including amplifiers, antenna tuners, filters, and imaging devices. Given its small size and excellent temperature performance, the HKQ040239NJ-E can also be used in portable electronic devices. Its radial-lead design contributes further to its versatility and usefulness in tight or cramped spaces.

Working Principle

As current flows through the inductor’s coil of wire, a magnetic field is generated which induces voltage in itself. This induced voltage, known as back-EMF, opposes the applied voltage and restricts current flow. By changing the amount of windings in the inductor, different levels of inductance can be achieved, enabling precise adjustments of current and voltage in a circuit. In the case of the HKQ040239NJ-E, its parameters are fixed and it is not adjustable—instead, its ports are used solely to allow current to flow through.

Conclusion

The HKQ040239NJ-E is an example of a fixed inductor, used to regulate currents and voltages in electronic circuits. This unshielded component has a valid temperature range between -55°C and +125°C and its small form factor makes it a great choice for portable electronic devices. It can be used in a variety of applications, including voltage regulation, power supplies, switching circuits, and telecommunication devices.
