Fixed Inductors
Inductors are electrical components used in a variety of electrical circuits to create or store magnetic fields. They are typically composed of metal coils wound around a core material, such as a ferrite or iron, and are usually placed in electronic circuits to provide inductive reactance.This type of inductor is fixed, meaning its resistance does not change. The PL9131NL is a type of fixed inductor designed for use in switching power supplies, DC-DC converters, and other power electronics applications.
The PL9131NL is a high-performance inductor that exhibits low loss and high efficiency in the 500kHz-2MHz frequency range. It has low stray magnetic fields, low heat generation, and low ESR (equivalent series resistance). The PL9131NL is ideal for use in power converters, as it can handle high currents and supports high switching frequencies while providing good current snubbing and low noise. It\'s also thermally and mechanically stable, enabling it to be used in a variety of applications.
The PL9131NL is available in two inductance values: 1.05mH and 2.2mH. The maximum DC current is 24A, and the rated saturation current is 20A. The rated AC current is 4.8A, with an achievable ripple current of about 8A. The inductance tolerance is ±20%. The device is encapsulated in a wire- or pin-type package, and has an operating temperature range of -40°C to 125°C.
In terms of construction, the PL9131NL is composed of a ferrite core and a copper or aluminum wire coil. The core is composed of two identical cylindrical parts with metal caps on either end. The wire coil is encapsulated within the ferrite core, which minimizes losses in the magnetic field due to eddy currents. The wire coil is also insulated with an isolating film to reduce leakage and noise.
The working principle of the PL9131NL is the same as that of any other inductor. When an alternating current is applied to the wires in the coil, a magnetic field is created around them, which then induces a voltage in each wire. The amount of voltage and current produced is determined by the amount of impedance placed on the coil by the core material. When a DC current is applied to the wires, the core material behaves like a short circuit, allowing the current to pass through unimpeded, leading to low losses.
The PL9131NL is an excellent choice for use in power converters and other power electronics applications due to its low loss and high efficiency in the 500kHz-2MHz frequency range. It can also handle high currents and supports high switching frequencies, making it a great option for high-power applications. Its temperature stability and low magnetic fields make it an ideal solution for applications in harsh environments.
