Fixed inductors are devices that store energy in a magnetic field when current flows through them. The most common type of inductor is the air-core or ferrite-core inductor. The SDR2207-820KL is an air-core inductor that can be used in various applications. In this article, we will discuss the application field and working principle of the SDR 2207-820KL fixed inductor.

SDR 2207-820KL fixed inductors are widely used in a wide range of applications. Examples include switching power supplies, DC-DC converters, radio frequency and high frequency amplifiers, and electromagnetic interference suppression applications. It is an ideal choice for high-power applications due to its high current capability and high peak current rating. The SDR 2207-820KL inductor is a low-cost solution that is reliable and easy to integrate into existing circuits.

When current flows through the coil of the SDR2207-820KL inductor, a magnetic field is created and stored in the inductor. This magnetic field induces an electromotive force (EMF) in the opposite direction of the current, which opposes the flow of the current. This is called the back-EMF, or self-inductance. The inductor\'s total impedance is the sum of two components, the resistive component and the inductive component, which are both affected by the frequency of the current. The inductive impedance is highest at the resonant frequency of the inductor, and decreases with lower frequencies.

The SDR2207-820KL is also able to dissipate heat quickly due to its low thermal resistance. This is especially useful for applications where high power and energy is required. The SDR 2207-820KL fixed inductor is rated for operating temperatures of between -40°C to +85°C and offers mechanical and electrical stability over its operating temperature range.

The SDR2207-820KL inductor is also very reliable and robust. Its high-temperature solder joints ensure that the inductor will not delaminate and will withstand high environmental conditions. It also has short-circuit and over-current protection to prevent damage to the inductor.

In summary, the SDR 2207-820KL fixed inductor is a reliable, robust device that can be used in a variety of applications. It is rated for high temperatures and is capable of dissipating heat quickly. It also provides excellent inductive and resistive characteristics, making it an ideal choice for high-power applications. Additionally, it is protected against short-circuit and over-current conditions.
