2500-70F

Fixed Inductors

A fixed inductor or choke is an electronic component that stores electrical energy in the form of inductance. It consists of a coil of wire around a ferromagnetic core and generates a steady magnetic field when a current flows through the wire. It is used in a variety of applications ranging from power supply and amplifier circuits to signal conditioning, radio modulation, and rectifier circuits. Inductors are available in a variety of values, sizes, and shapes, and can be classified based on their design and construction.

2500-70F Application Field

The 2500-70F is a fixed inductor manufactured by the company\'s High Frequency Electronics division. It is a compact, multi-layer, wide-frequency range inductor suitable for a wide range of signal processing and RF applications.

The 2500-70F is used in RF power amplifier applications, radio modulation, high-frequency signal conditioning, and frequency-selective networks. It is also used in switching power supplies, linear and switching regulators, and audio circuits. The 2500-70F is designed for high-frequency applications, with an upper frequency range of 1MHz to 5GHz.

The 2500-70F is available in multiple versions, with inductance values up to 68nH and maximum DC current ratings up to 20A, depending on the version. It is a low profile device with a 4mm height, making it easy to mount and use in small spaces.

Working Principle

A fixed inductor works by creating and storing a magnetic field in its core, induced by a current passing through the coil. The magnetic field stores energy, which is released when the current is reduced or removed. This creates an opposing voltage that tries to maintain the current, preventing abrupt voltage changes.

The 2500-70F is constructed using special winding techniques that increase the inductance and provide better efficiency and higher current ratings. It also uses multiple layers of cores to reduce the size and increase the inductance values.

The 2500-70F operates over a wide frequency range, thanks to its low resistance (DCR) value. The DCR of this fixed inductor is as low as 0.39mΩ, ensuring that the inductor can operate over a wide range without introducing excessive losses.

Conclusion

The 2500-70F is a fixed inductor suitable for a wide range of applications, from RF power amplifiers to switching power supplies. It is a very low profile device that is easy to mount and use in small spaces. Thanks to its special winding techniques and multi-layer core construction, the 2500-70F has a wide frequency range and high inductance values.
