Fixed Inductors

Fixed inductors are electrical devices that store energy, resist changes in electric current and produce magnetic fields. SC3308F-100 is a type of fixed inductor constrained in winding ferrite material. It is specifically designed to provide a wide range of inductance values in high impedance and moderate current load in a variety of applications, such as DC-DC converters, EMI filters, pulse generation circuits and motor circuits.

SC3308F-100 Application Fields

SC3308F-100 is commonly used in electronics for power applications, including:

• DC-DC converters – It can be used for DC-DC buck or boost converters, as well as buck-boost and 36 V buck converters.
• EMI filters – It can be used to provide high quality, low ripple, and EMI suppression.
• Pulse generation circuits – It can be used for high frequency switching power delivery, timing, and critical pulse applications.
• Motor circuits – It can be used for motor circuits, such as brushless DC (BLDC) motor and stepper motor control.

The fixed inductor can also be used in overall power management in conjunction with other components, such as transistors, capacitors, and resistors. The use of SC3308F-100 in each application requires careful analysis and selection of the right component and circuit.

SC3308F-100 Working Principle

The primary components of a fixed inductor are the core windings and core material. The core material is a ferrite material that acts as an electromagnetic shield and also creates a path for the current to flow in the inductor. The windings consist of a number of insulated copper wires. When current flows through these wires, an electromagnetic field is generated which is proportional to the current. This electromagnetic field stores energy in the form of magnetic flux.

The inductance value of the SC3308F-100 is dependent on the core material, the number of windings, and the size and shape of the core. The inductance value can range from 1 to 2,000 uH. At large currents, the inductor acts like a resistor and will start to heat up due to the power dissipation. The power loss increases as the current or frequency of the signal increases.

The SC3308F-100 can also be used in high-frequency switching applications, as it can handle up to 2 A of current with very low DCR and high saturation currents. The high current carrying capability and low DC resistance make it suitable for high frequency switching applications such as motor control circuits.

Conclusion

SC3308F-100 is a type of fixed inductor constrained in winding ferrite material. It is specifically designed to provide a wide range of inductance values in high impedance and moderate current loads. It is commonly used in DC-DC converters, EMI filters, pulse generation circuits, and motor circuits. The working principle of SC3308F-100 is based on the core material, the number and size of the windings, and the size and shape of the core.
