Fixed inductors are used to efficiently handle large currents by providing a stable magnetic field. The inductance value of an inductor is determined by its geometry and the type of material used. Fixed inductors are available in various sizes and shapes, from flat spiral coil to pin-shaped. They are in common use to generate inductance in a wide variety of electronic applications, from motors to power supplies. This article will look in detail at the SC3DF-3R3 application field and working principle.

The SC3DF-3R3 is a flat spiral wound inductor. Its design is based on the traditional flat spiral coil concept but with improved mechanical and electrical characteristics. It is made of an inorganic powder core and flat wire conductor with a spiral winding pattern and an epoxy encapsulation. The inorganic powder core provides the inductor with an excellent thermal stability, low DC resistance and low ESR (Equivalent Series Resistance).

The SC3DF-3R3 is typically used in DC to low frequency AC applications including switching power supplies, inverters, step motors and regulators. Its wide operating range makes it ideal for a variety of applications including low voltage power supplies, UPS (uninterruptible power systems), adjustable speed motors and voltage multipliers. The flat wire conductor also reduces inductor core losses which further improves efficiency while providing excellent temperature stability.

The SC3DF-3R3 working principle is based on the principle of inductance. When a current passes through the inductor, a magnetic field is created. This magnetic field produces a force, which opposes the current and generates an inductance. The amount of inductance depends on the number of turns in the inductor and the ratio of the area of the inductor to the available air gap. The larger the number of turns and the smaller the area to air gap ratio, the greater the inductance. The SC3DF-3R3 has an inductance value ranging from 1.2 to 35µH (microhenries).

The SC3DF-3R3 is also equipped with a deep internal Electro Magnetic Interference (EMI) filter which prevents signal distortion from passing through. This allows the inductor to provide excellent filtering and low noise performance. It can also be used for power factor correction in motors by providing a low-impedance path for starting current.

Overall, the SC3DF-3R3 is a reliable and efficient inductor for DC to low frequency AC applications. Its high inductance value, low DC resistance and low ESR make it an ideal choice for power supplies, UPS systems and adjustable speed motors. Its deep internal EMI filter ensures excellent signal filtering and noise reduction. Additionally, its inorganic powder core provides excellent thermal stability and excellent temperature stability. These key features make the SC3DF-3R3 an ideal choice for applications requiring reliable and efficient inductors.
