Fixed inductors are components used in a variety of electronics applications. The 2512-123F is an example of a fixed inductor which has several unique attributes that make it advantageous for certain operations. This article will discuss the applications and working principles of the 2512-123F fixed inductor.

Description and Properties

The 2512-123F is a fixed surface mount inductor from Pulse Electronics’ DLPN series offering low, DC losses and very high current DC bias capabilities. This exceptionally low core loss product has a maximum operating temperature of 155°C. It features a ferrite core material with an efficient air gap for improved frequency response and balance. It has a nominal inductance of 15nH with a tolerance of 10%, a maximum DC current of 7.2A, and a rated AC current of 1.2A peak.

Applications

Due to their exceptional DC bias capabilities, the 2512-123F inductors are often used in a variety of power conversion products such as power supplies, telecommunications, and automotive applications. Their high-temperature operation capability and low inductance values are ideal for high-frequency switching converters. They can also be used in impedance matching and voltage-regulator circuits.

The 2512-123F inductors are also widely used in RF/Microwave applications, such as cavity resonators, RFID readers, and high-speed wireless or cellular communications. Any application requiring a stable inductance over a wide temperature range or high-current DC bias levels will benefit from the 2512-123F inductors.

Working Principle

Inductors are passive electrical components consisting of a coil of wire that stores energy in the form of a magnetic field when a current flows through it. The amount of inductance is an intrinsic property of the coil, and is directly related to the number of turns in the coil, the coil dimensions, the core material used for the coil, and the surrounding environment. The energy stored in the magnetic field can be released when the current is interrupted and dissipated into the surrounding environment as heat.

In the 2512-123F inductor, the ferrite core material and air gap provide excellent stability over a wide temperature range and allow the inductor to handle high current DC bias levels. The air gap reduces the magnetic core’s inductance when current is applied, which then reduces the power losses due to hysteresis. The high level of temperature stability also helps to ensure accurate performance in high-temperature environments.

Conclusion

The 2512-123F fixed inductors offer some of the best performance and reliability of any inductor currently available. Their high-temperature operation capability and low inductance values are perfect for high-frequency switching and power conversion applications such as power supplies, telecommunications, and automotive applications. Their properties also make them suitable for RF/Microwave applications such as RFID readers and high-speed wireless or cellular communications. Combining high stability, temperature performance and low losses, the 2512-123F is an ideal solution for a variety of applications.
