PTKM250R-121H

Fixed Inductors are electronic components used to generate a consistent electric current in electronic circuits. The PTKM250R-121H is one type of fixed inductor which is widely used in a variety of applications.

The PTKM250R-121H is an axial leaded fixed inductor with a dielectric material made of molded plastic. It is designed for high temperature of up to 105 degrees Celsius, so it can be used in many types of high temperature applications. It has a rated inductance of 250 µH, with tolerances of ± 5%, and is rated for current up to 0.8 amperes (A) with a maximum voltage of 55 volts. This device is also polarised, meaning that the leaded end should always be connected to the positive voltage source.

The PTKM250R-121H is used in a variety of applications, including power electronics, automotive electronics, telecommunications, and industrial electronics. In power electronics, the device is used as an inductor in diode and MOSFET-based AC-DC and DC/DC converters, as well as in DC-AC inverter circuits. It is also used in automotive electronics, telecommunication, and industrial electronic applications, such as in circuit protection, switch-mode power supplies, filters, radio frequency interference (RFI) protection, and motor control.

The working principle of the PTKM250R-121H involves the passing of an electric current through its windings. This current creates an electromagnetic field in the core of the PTKM250R-121H, which induces an opposing voltage across the windings. This voltage is proportional to the rate of change of the current in the circuit. The voltage generated by the PTKM250R-121H creates an opposing current in the circuit, which serves to oppose the change of current in the circuit, thereby producing a “fixed” current flow in the circuit. As a result, the current in the circuit remains consistent, even when the load varies.

In conclusion, the PTKM250R-121H is a fixed inductor which is designed for high temperature applications, and is used in a variety of different applications, such as power electronics, automotive electronics, telecommunications, and industrial electronics. Its working principle involves the passing of an electric current through its windings, which creates an opposing voltage across the windings, resulting in a fixed current flow in the circuit.
