PTKM150-40SM

Fixed Inductors

A fixed inductor, also known as a choke, is a passive two-terminal electrical component used in electronic circuits to maintain a constant electric current. Inductors come in many shapes and sizes, from tiny chip inductors used on PC boards, to large power line “chokes”. The PTKM150-40SM is a tamper-proof, self-leakage protection fixed inductor made with a metalized polyester film dielectric. It is designed for a range of DC to 40MHz and is suitable for high-frequency application, such as telecommunications and automotive use.

PTKM150-40SM Application Field

• Power regulator circuits: The PTKM150-40SM can be used in power regulator circuits to regulate current and voltage levels.
• Automotive applications: The PTKM150-40SM is well-suited for automotive applications, such as electric motor control, power window, and speed control.
• Telecommunications: The PTKM150-40SM can be used in telecommunications systems, such as cellular phones, radio systems, and other high-frequency applications.
• Audio/Video: The PTKM150-40SM is also used in audio/video applications, such as amplifier systems and other related applications.

PTKM150-40SM Working Principle

The PTKM150-40SM inductor works on a very specific principle. It functions due to the magnetic fields that are produced when current passes through the inductor. This principle is based on Faraday’s law of induction. The PTKM150-40SM induces a magnetic field in the presence of a current flow which is proportional to the current. The magnetic field produced will then oppose the flow of current. This eddy current opposing flow will create a voltage drop across the inductor that is proportional to the rate of change in the magnetic field.

The PTKM150-40SM is designed to have an extremely low self-leakage current, making it suitable for high-frequency applications. The self-leakage current is controlled through the use of a metalized polyester film which prevents the eddy current opposing flow from forming, thus allowing only a small current to pass through.

Conclusion

The PTKM150-40SM fixed inductor is a tamper-proof, self-leakage protection inductor made with a metalized polyester film dielectric. It is specifically designed for DC to 40MHz range applications in the fields of automotive, telecommunications, and audio/video applications. The PTKM150-40SM works on the principle of Faraday’s law of induction and generates a magnetic field proportional to the current flow. The self-leakage current is small due to the use of a metalized polyester film dielectric.
