Fixed inductors are electrical components with an inductance, or the capability to store energy within an electromagnetic field. The SP1210R-124G fixed inductor takes this fundamental functionality and adds exceptional power efficiency within a reasonably small package. This inductor features a generous operating temperature range, up to 125°C. Additionally, the component is specifically designed for use in high frequency switching applications.

The core construction of the SP1210R-124G adds to its power efficiency. Instead of using the typical ferrite or iron core, this inductor uses a manganese zinc metal core. This altered composition increases the inductor’s efficiency by reducing the core losses. Additionally, this metal core composition helps reduce the overall size of the component. This is ideal for applications that would benefit from a larger inductance, but do not have the size requirements for a bulkier inductor.

The constructional parameters and design details of the SP1210R-124G further enhance its power efficiency. For example, this inductor features a mu-metal sheath and vertical winding that adds to its current-carrying capacity. These constructional features reduce the component’s eddy current losses, allowing it to retain performance under heavy switching. In addition to its current-carrying capacity, the SP1210R-124G features an UL 94V-0 flame retardant insulation. This insulation improves the component’s overall insulation resistance which adds to its power efficiency.

As with all inductors, the SP1210R-124G creates a magnetic field by passing current through a coil of wire. This action creates and stores energy within the magnetic field. During times when the current is removed, the magnetic field collapses and supplies an opposite voltage, either stabilizing or restoring the voltage in a circuit.

The operating principles of the SP1210R-124G are ideal for multiple applications. For example, in the automotive industry this inductor works well for driver circuitry. In this application, the SP1210R-124G is responsible for the driving of electrical loads, such as motors. Additionally, the inductor works well for energy management applications such as power inverters. This type of application requires quick switching to ensure the inverted power remains undistorted.

The SP1210R-124G is also suitable for battery charger design applications. The inductor’s robust construction and wide operating temperature range allows the component to operate safely within a battery charger’s higher output conditions. Finally, this inductor is ideal for medical applications, as it features a class B insulation system that is certified to UL standard 5117.

The SP1210R-124G fixed inductor is a unique component designed to provide superior power efficiency without increasing bulk or size. Its signature manganese zinc metal core construction reduces core losses, while its UL 94V-0 insulation ensures reliable operation under heavy switching. The operating principles of this inductor make it ideal for applications such as automotive drivers, power inverters, battery chargers, and medical applications.
