Fixed Inductors

The 4922-14L Inductor is a uniquely designed component that acts as a passive filter element. It is used in circuits for a variety of applications that include energy storage and electrical noise suppression. It is categorized as a fixed inductor because it can not be adjusted or tuned within its application circuit. Although this type of inductor does not have the ability to be tuned, it can still provide filter element qualities critical for many applications.

The principle operation of the fixed inductor is based on those utilized by variable inductors, which operate by varying a magnetic field within an inductive element. A protrusion stopper, also known as a slug, introduces a variable field to the inductance element which is then released when the slug is removed. Fixed inductors contain a magnetic core and do not contain a slug.

The 4922-14L Inductor is one of the most popularly used fixed inductors on the market today. It has a rated operating temperature of -40°C to 125°C and has a typical inductance of 80μH ± 20%. This component is ideal for high power applications in which superior heat dissipation and a wide operating temperature range are not available. It features a very compact housing, making it a great choice for applications in cramped spaces.

The most common application for the 4922-14L is in automotive equipment, ranging from automotive audio systems to car starters. It is also found in laptops and other consumer electronic products. It is capable of providing an effective inductance in the range of 1 to 330μH, making it a great choice for limiting power supply ripple, managing high current spike, or for providing impedance. Its high resistance to humidity as well as its ability to dissipate heat quickly make it a great choice for these applications.

The 4922-14L also offers excellent shielding and noise protection. Its small size and high inductance make it the ideal choice for secondary filtering of high current loads, such as in a secondary power supply circuit. The components are also available in a 100μH version, making it an ideal choice for noise suppression in powerlines. In short, the 4922-14L offers an effective, reliable, and robust solution for many of today’s loud, high current circuit designs.
