Fixed inductors refer to passive component that stores electric energy in the form of magnetic field when an alternating current is applied to it. The SC32-820 is a fixed inductor that is suitable for a variety of circuits, including in-circuit or inverter based switch-mode power supplies (SMPSs).

Although it has a maximum operating temperature of 125°C, the SC32-820 offers excellent temperature characteristics with a low temperature coefficient of less than 0.3%. The inductance is designed for a minimum of 1.20 mH at 1 kHz, with a maximum DC resistance of 0.020 Ω. The maximum rated current is 1.2 A.

The SC32-820 fixed inductor is available in both radial and axial designs with a wide range of inductance values from 1uH up to 47uH. It features an ideal inductance to resistance ratio of at least 1.2 mH to 0.02 Ω, which ensures robust performance over a large frequency range. This makes the inductor suitable for use in SMPSs as well as in RF applications.

The inductor is constructed with materials that make it suitable for a range of applications including automotive, lighting, and control systems. It is designed with an air core, which allows for higher inductance values. The SC32-820 also features molded-in internal fusing to protect against over-currents. This makes it especially suitable for use in precision control applications, as well as in circuits that require current protection.

The working principle of the inductor is simple. When electric current passes through the device, a magnetic field is generated, which induces a voltage across the terminals of the inductor. When the applied electric current alternates in direction, reverse EMF is produced within the inductor. The reverse voltage reduces the strength of the magnetic field, and thus produces the desired inductance effect.

The SC32-820 fixed inductors offer superior performance with its low temperature coefficient, high rated current, and ideal inductance to resistance ratio. It is suitable for a variety of circuits, including in-circuit or inverter based switch-mode power supplies, automotive, lighting, and control systems. Its construction also allows for a range of energy storage capabilities and current protection, making it an ideal choice for precision control applications.
