Fixed Inductors: SDR0906-822KL Application Field and Working Principle

Fixed inductors are an important component in the field of electrical engineering, providing inductance without the need for maintenance and adjustment. The SDR0906-822KL is a fixed-value inductor designed to reduce voltage and current spikes during system start-up, while also providing improved signal integrity and maintaining a very low level of interference. This article will explain the application field and working principle of the SDR0906-822KL.

Application Field

The SDR0906-822KL is designed for use in high frequency circuits that require the absorption of high frequency signals, while still maintaining a low level of electrical noise. This inductor is ideal for ELV, SMPS, and switching regulator applications, due to its ability to reduce inrush current and voltage spikes. The inductor can also be used to minimize Electromagnetic Interference (EMI) in power supplies and other radiation sensitive circuits. This inductor is also suitable for use in low-input-impedance DC-DC buck converter applications, as it helps to reduce the input ramp voltage.

Working Principle

The SDR0906-822KL works on the principle of inductance, which is the characteristic of an electric circuit that opposes any change in current. The inductor is a coil of wire (or other conducting material) that acts as an inductor. The inductor’s resistance to any change in current causes the current to increase in proportion to time, therefore creating back-EMF. Back-EMF is the force that opposes current flow and causes a voltage drop across the inductor. This voltage drop slows the rate of current flow and prevents voltage spikes, thus protecting the circuit.

The SDR0906-822KL fixed value inductor features a flat-top construction, which reduces the peak-to-peak inductance ripple. This inductor is also constructed with oxygen-free copper wire, which improves efficiency. The SDR0906-822KL also features an epoxy insulation, which ensures stability and increases the temperature range for operation.

Conclusion

The SDR0906-822KL is a fixed value inductor designed to reduce voltage and current spikes during system start-up, while also providing improved signal integrity and a low level of interference. This inductor is designed for use in high frequency circuits, as it helps to reduce inrush current, voltage spikes, and EMI. The inductor also features a flat-top construction, which reduces ripple, and oxygen-free copper wire, which improves efficiency. The SDR0906-822KL thus offers a reliable and long-lasting solution for a wide variety of applications.
