Fixed inductors are components used to store energy through an electric field in a static state, discharging a current when needed. The SRR1280-821K is one type of fixed inductor. This component is especially effective in occasions for which small size and high performance are needed, such as amplifier circuits. It contains a low profile, stable structure perfect for automotive and other compact applications.

The SRR1280-821K fixed inductor is wound with a single layer copper wire, permitting an even and consistent current distribution. It also has a solder dip finish, which allows for quick and effective mounting in limited spaces. Additionally, the SRR1280-821K has a high resistance to solder heat, with the component showing no signs of damage after being reheated up to ten times.

In terms of performance, the SRR1280-821K fixed inductor has an inductance value of 4.7uH, a current rating of 1.4 A and a rated voltage of 70V. It is able to operate at temperatures ranging from -40°C to +125°C, and can handle pulse and continuous current applications alike without compromising on longevity and dependability. The component’s internal structure is composed of copper and silver plates which reduce the harmful effect of high frequency electromagnetic fields from affecting its efficacy.

The SRR1280-821K fixed inductor’s working principle is the inductance of electric current across a coil or an enclosed wire in a permanent magnetic field or an alternating field. When an inductor is introduced to a varying current, a magnetic field with a direction perpendicular to the magnetic field is generated. This induces a flux in the inductor, which creates an opposing electric field proportional to the current rate of change within the inductor. This electric field then acts on the current, generating a voltage that opposes the change of the current and the inductor stores energy, which can then be released when needed.

The SRR1280-821K fixed inductor therefore is suitable for a wide range of applications, from high powered audio amplifiers to power supply circuits. Its combination of a low profile, high performance and wide operating temperature make it the perfect component for automotive applications and any other situation where small size and dependability are of paramount importance.
