Fixed Inductors

A fixed inductor, or \'fixed or non-variable\', is an electrical device whose inductance value remains constant, despite fluctuations in the external circuit variables such as frequency, temperature and current. It is used in various applications such as: audio, filtering, suppression, radio frequency communication, magnetic recording and other power supplies. Fixed inductors come in many shapes and sizes, depending on their applications.

PTKM150-50H Application Field and Working Principle

PTKM150-50H is a fixed inductor manufactured by Tokin Corporation. This fixed inductor is a type of air core inductor, characterized by having a low distributed capacitance and being highly resistant to external noise. Its inductance is 150uH, and it is suitable for a variety of electronic applications with currents around 50A~150A.

The basic working principle of a fixed inductor is that it produces a magnetic field when applied with a current, and this magnetic field then induces an electromotive force in the inductor. This force is then used to produce energy. PTKM150-50H is designed for high power applications such as motor and energy conversion circuit, filter and feedback applications, as well as automotive purposes.

PTKM150-50H features a compact and reliable design. The package is composed of a coil, a core made of silver-plated metal, and a plastic bobbin. The bobbin contains several layers of insulation material to prevent the current from shorts. The core is further surrounded with a copper conductor that helps in increasing the power output. This fixed inductor has a maximum rating of 150 mΩ, and it can be used in temperatures ranging from -40°C to 125°C.

The PTKM150-50H also offers very low distributed capacitance for power conversion and filtering purposes. Its maximum DC resistance is 0.5Ω, while its maximum temperature range is 115°C. It is also highly resistant to noise, thanks to the advanced magnetic field interference cancellation technology used by the company.

PTKM150-50H is suitable for use in a variety of applications, including high power DC to DC conversion circuits, audio power amplifiers, automotive supplies, motor control, magnetic recording and other use cases. It is an extremely reliable device that can be used for various purposes in the industry.
