Fixed Inductors

Inductors are electrical components comprised of conductive material that can store charge and energy, and can also be used to provide resistance and to regulate electrical current. Fixed Inductors, in particular, are designed to provide a fixed value of inductance. They are used in a variety of applications, such as circuit boards, antennas, and amplifiers, and are available in various forms including axial, radial, surface-mount, and through-hole packages. The 2890-28H, in particular, is a high-performance, fixed-inductance, eight-pole chip inductor that is an ideal choice for applications where space is a constraint.

This device is constructed with advanced advanced multi-level interconnects and ferrite material technology, which allows it to perform with very low resistance and higher current handling, even at lower frequencies. It has a very small footprint, measuring just 0.370 x 0.250 x 0.063 inches (9.4 x 6.35 x 1.60 mm), making it ideal for applications where space needs to be conserved. Its rated current is 4.0A, while its rated DC resistance (DCR) range is from 0.011Ω to 0.015Ω, depending on the operating temperature.

The 2890-28H’s application field covers broadband communication circuits, including cellular phones and base-stations. It is widely used in portable and wireless applications, such as GPS tracking and wireless security systems. It optimizes wireless performance in CC2500 and MiWi platforms, and simplifies the user’s implementation of their wireless systems. The device also features a high quality factor (Q), ranging from 0.32 to approximately 0.50, as well as excellent temperature and power stability.

The 2890-28H operates on the principle of inductance, which is the quality of an inductor to store energy, in the form of a magnetic field, when current passes through it. An inductor is basically a conductor that has been appropriately wound around a coil, and, when current is passed through it, generates a magnetic and electric field. This in turn causes the current to be drawn back into the coil, thus reducing the current flowing in the circuit. As the current gradually reduces, this causes a decrease in the voltage across the inductor. This is known as inductance, and can used to regulate current, reduce noise, and store energy.

The 2890-28H is an excellent choice for applications requiring a small fixed-inductance component, as it provides efficient, reliable performance in a very small package. This device provides optimal performance in applications ranging from communications systems to portable devices, with its low DCR, high current rating, and excellent temperature and power stability. Its small footprint also makes it a great choice for applications where space needs to be conserved.
