PE-53119NL

• PE-53119NL Application Field and Working Principle
• Fixed Inductors

Fixed inductors are widely used passive components which store energy in the form of magnetic fields as current passes through them. They are constructed from coils of insulated wire wrapped around either a ferrite core, a toroidal core, or an open spirit core. Inductors can vary in size and shape and can be standard, molded, or custom-made. PE-53119NL is a molded inductor which is well suited to applications including filters, chokes, as well as dc-dc and RF circuits. It is a low-cost, high-performing product which is rated to 1A and 130mH with a temperature coefficient of ±100ppm/°C.

Application Fields

PE-53119NL molded inductors are great for applications where small space is available. It is ideal in switching power supplies and used to filter and supply power to the device. It can be used to eliminate noise or interference in the output of an electrical system. Commonly used for voice coils, clock oscillators, and chokes. It can be useful in medical systems, cell phone applications, and computer systems. Other applications include radio receivers, CCD circuits, camera circuits, computer graphic boards, switching power supplies, and AC/DC adapter circuits.

Working Principle

The PE-53119NL functions by storing energy as a magnetic field when current is passed through its coils. When a conductor is formed with current, it generates a magnetic field in the space outside of the conductor which is referred to as a magnetic flux. This creates a sort of barrier to current passing through the core of the inductor. Since energy must be lost when the magnetic field collapses, these inductors are used to filter, shape, or delay the current. The inductance of these inductors is primarily dependent on the number of turns in its coils, its cross-sectional area, and the permeability of the core.

Frequency Considerations

The PE-53119NL is rated for high frequency applications and its electrical characteristics are tested up to at least 100kHz. When used in an application that requires higher frequencies, be sure to confirm that the peak current will not exceed the maximum current rating as this can cause overheating and reduce the overall life of the product. Additionally, as the frequency of the circuit increases, it is important to consider the inductance value of the inductor as it may have to be increased in order to reduce power losses which are the result of the core’s resistance to the current.
