Fixed Inductors

An inductor, also known as a coil, choke or reactor, is a a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. It\'s principle of operation is based on that an electric current flowing within the inductor creates a magnetic field around the element, and when the current begins to change, the field also changes, creating an electromotive force (EMF) in the element, proportional to the rate of change of the current. Inductors are generally used in electronic applications such as filtering and tuning circuits.

SPM12565XT-2R8M150

The SPM12565XT-2R8M150 is a high performance fixed inductor from Digi-Key Corporation, with an rated current up to 3 amps. The device features high saturation flux density, low profile height, good long-term stability, wide temperature range, high Q factor and high efficiency. This product is suitable for a wide variety of applications such as DC-to-DC conversion, switching regulators, buck converters, inverters, choppers, electrical motors, deflection circuits and resonant circuits.

Application Field and Working Principle

The SPM12565XT-2R8M150 is well suited for various power electronics applications, particularly those require a high inductance and low equivalent series resistance (ESR), due to its low interwinding capacitance and low-frequency capacitance. It is especially suitable for large-power converters such as soft-switching who have a higher dc component on the conditioned signal than conventional pulse-width modulation (PWM) method.

In these applications, the SPM12565XT-2R8M150 operates at high temperature and high frequency level, with very low DCR and high interference rejection capability, as well as very low audible noise level. At this time, an SPM12565XT-2R8M150, through its flux linkage, transfer a controlled amount of energy from the input side of the circuit to the output side, creating a constant voltage and current drop across the two sides, while allowing very high efficiency and low noise.

Overall, this particular inductor is an excellent choice for a wide range of power electronics applications, thanks to its high saturation flux density, low profile height, good long-term stability, wide temperature range, high Q factor and high efficiency.
