P3519R-155J Inductors, Coils, Chokes

Fixed Inductors

A fixed inductor, often referred to as a choke or coil, is an electronic component that\'s found in power supplies, radio frequency (RF) circuits and other electronic circuits. It is used to store energy in an electromagnetic field, which can be tapped by connecting a source of current to the inductor.

The P3519R-155J Inductor is a high-reliability, miniature radial leaded inductor designed for high volume telecommunications markets. It is made to offer reliable performance, even in harsh conditions, over a wide temperature range (-40°C to +85°C). It features a maximum of 6% tolerance, an SRF rating of 125MHz, and a maximum DCR of 0.15Ω at 25°C.

Application Field

P3519R-155J is typically used in telecommunications equipment such as switching systems, routers, voice over IP, satellite systems or any other equipment that relies on inductive components for filtering of high frequency signals. Additionally, it is also used in power supplies, radio frequency (RF) circuits and other electronic circuits.

Working Principle

An inductor works by converting electrical energy into magnetic energy which is then stored in a magnetic field. When a current is applied to the inductor it creates a magnetic field which induces a voltage that opposes the current. This is known as inductive reactance. The amount of inductive reactance is determined by the inductance of the inductor and the frequency of the current. The higher the inductance, the greater the voltage induced, which reduces the current flowing through the inductor.

The P3519R-155J has a high inductance rating, allowing it to have a higher voltage drop when current is applied. This feature makes it ideal for filtering high frequency signals. Additionally, it has a high SRF rating which is important for maintaining signal integrity. As the frequency of the signal increases, the inductor is able to maintain its signal strength more effectively than a lower quality inductor.

Conclusion

The P3519R-155J is a high-reliability, miniature radial leaded inductor designed for high volume telecommunications markets. It is capable of operating in harsh conditions over a wide temperature range. This inductor is suitable for filtering high frequency signals in telecommunication equipment and other electronic circuits.
