PTHF150-121

Fixed Inductors

• The PTHF150-121 is a low cost, radial leaded inductor with a fixed value. It has a DC resistance of 0.6 Ω and can handle a rated current of 1 A. It has a saturation current of 2A and an inductance of 150mH. The PTHF150-121 is widely used in low power applications such as inverter circuits, motor control circuits, resonant circuits and DC-DC converters.

• The working principle of the PTHF150-121 is based on the fact that a current carrying coil around a core creates a magnetic field in the core. This field is further strengthened by an iron core. The generated field then opposes the current in the coil, generating opposition to the current. This opposition is called inductance and this inductance can be increased or decreased by changing the number of turns in the coil. The inductance of the PTHF150-121 can be adjusted by adding or removing turns in the coil.

• The PTHF150-121 has a wide range of applications due to its low cost and ability to handle higher currents. It can be used in circuits such as switching power supplies, DC-DC converters, regenerative circuits, motor control circuits and resonant circuits. It can also be used in audio amplifier circuits to provide high-level tone control. In addition, the PTHF150-121 can be used in low frequency applications such as in transmitters, receivers and filters.
