4494R-225

The 4494R-225 is part of a wide range of fixed inductors, designed to deliver a range of specific inductance values. This type of inductor is commonly used in radio frequency (RF) applications, where precision inductance is required. It is extremely important that inductors retain their inductance values over time to accurately replicate a predefined frequency.

An inductor works by storing magnetic energy from an alternating electric current, using two components: an iron core and coil of wire. The iron core serves to concentrate the magnetic field and increase the measurements of the inductor. The AC signal runs through the coil of wire, creating a time-varying magnetic field, and this in turn creates a time dependent voltage across the inductor.

The 4494R-225 fixed inductor has a range of 0.005 to 0.02 micro Henrys (µH) inductance, and a maximum DC current of around 5000mA. This type of inductor is particularly suitable at frequencies below 1 MHz and when 4494R-225 inductors are incorporated in a series the total inductance is additive. They are relatively inexpensive, making them a cost-effective choice for many applications.

The 4494R-225 inductor is used in a wide variety of applications where the need for high power and low losses is important. These include use as filters, oscillators, power supplies, meters and modulators. Common uses include radio receivers, computer motherboards and audio equipment. Additionally, because it withstands high temperatures and EM fields, the 4494R-225 is often used in applications such as automotive electronics.

The 4494R-225 is also used in circuit designs where it is important to maintain critical inductance values. The inductor can be used in conjunction with capacitors, resistors and other elements of an electronic circuit. For applications requiring high power, it can be connected in parallel with other inductors, which allows higher current ratings while keeping within temperature ratings.

Overall, the 4494R-225 is a reliable and effective fixed inductor. It is well-suited to applications such as RF, audio, automotive, and power supplies, where precision inductance values are required. Its wide range of inductance values also makes it a suitable choice for various circuit designs. It is relatively inexpensive and can withstand high temperatures, making it a popular component for many applications.
