PTKM150-30SM

Fixed Inductors

The PTKM150-30SM is an example of fixed inductors which are used in electrical devices. It is primarily used in switching power supplies and is a suitable alternative non-resonant inductor, due to its small size and weight. Other applications of fixed inductors include radio transmitters, filters and room temperature sets.

Fixed inductors have fixed inductance, unlike variable inductors, which can be altered to suit the application. Fixed inductors are used when a fixed inductance is required for the circuit, such as when calculating critical locations for voltage regulation or tuning sinusoidal oscillators. The value of the inductance remains unchanged under all operating conditions and is specified in the device datasheet.

The PTKM150-30SM is a fixed inductor designed for use in power supplies and is applicable to a range of applications. It has a nominal inductance of 10mH and is rated at an operating temperature of -55 to +125°C, which provides superior temperature stability and makes it suitable for use in higher temperature environments. It is also rated for a maximum current of 55mA.

The working principle of fixed inductors is based on the theory of electromagnetic induction, which states that a changing magnetic field, generated by a current, can induce an electromotive force in a conductor located in the same field. This electro-motive force will cause the flow of electrons, and thus an electrical current in the conductor. Fixed inductors work in a similar way, except that, instead of a changing magnetic field, the field remains constant, and the current flow is generated by the voltage across the inductor.

The PTKM150-30SM fixed inductor is constructed using an iron-core transformer which is wound with copper wire to form an inductor. The inductor is then encapsulated in an epoxy coating to protect it from the external environment. The construction of the PTKM150-30SM fixed inductor ensures that its inductance remains constant, thereby providing superior temperature stability.
