Fixed inductors are a type of electrical component whose inductance – the ability to store energy in the form of a magnetic field – is fixed, meaning it does not fluctuate with changing conditions. While inductors are often fairly simple to understand, their wide variety of specific characteristics and diverse applications make it important to understand the design and operation of each of them. One such device is the LQH2MCN820K02L, which uses magnetic induction to produce a constant inductance at a range of frequencies.The LQH2MCN820K02L is a monolithically integrated high frequency ceramic chip inductor typically used in the fields of audio amplifiers, voltage regulators, switching power supply, base station equipment, and mobile phones. The inductor’s size of 2.0 mm x 1.25 mm makes it space-efficient, fitting well with applications where space is at a premium. Its temperature range, between -40°C and +125°C, enables it to be used in extreme environmental conditions, and its EMS resistance makes it particularly suitable for applications which require immunity from electro-magnetic interference. These features, combined with its low cost and high power output, make it an attractive choice for various applications.In terms of its operation, the LQH2MCN820K02L uses a degree of self-inductance to generate a magnetic field that creates a constant output. As electrical current flows through the inductor’s coils, a magnetic field is generated that, while in the presence of the inductor, generates an opposing magnetic force on the current. This opposing magnetic force acts to resist the incoming current, effectively limiting the amount of current that can pass through the inductor and, by extension, the amount of power that can be output.The LQH2MCN820K02L’s inductance is fixed, meaning its current-limiting effect is relatively consistent over a range of frequencies. This enables it to maintain a constant output despite fluctuations in the electric current flowing through it. This makes the device useful in applications where a steady voltage is needed, such as in voltage regulators or audio amplifiers. Furthermore, the inductor’s self-resonance makes it capable of operating at frequencies as high as two gigahertz, making it suitable for radio frequency applications, digital signal processing (DSP) circuits, and base station equipment.The LQH2MCN820K02L is a compact and cost-effective device that flourishes in extreme temperatures and challenging electric environments. Its magnetically-induced constant inductance output makes it ideal for use in audio amplifiers, voltage regulators, switching power supplies, radio frequency communications equipment, and mobile phone circuit applications, among others. Owing its success to its cheap components, robust design, and wide range of operating frequencies, the LQH2MCN820K02L is an inductor of choice for many electronics engineers.
