Fixed inductors, also known as chokes or coils, are devices used to enable the transmission and reception of electrical signals while blocking other signals. They are available in various configurations, such as coreless, air core, actively-saturating core, and shielded ferrite-core types. Among these, the UP3B-6R8-R is a widely used shielded ferrite-core type inductor.

The UP3B-6R8-R is an 8-pin radial lead inductor with a shielded ferrite core. It operates across a temperature range of -40 degrees Celsius to +85 degrees Celsius, and has a maximum voltage rating of 16V. The other parameters associated with this inductor include a rated working frequency of up to 100MHz, inductance range of 1.5uH to 33uH, and current rating of 2.2A to 6.8A. It has an 8.2A maximum peak current rating and Ohmic resistance of 0.9m ohm to 8.01m ohm.

The primary application of the UP3B-6R8-R is to filter the signal in power supplies and to reduce cross-talk in data communication lines. It is ideal for low profile embedded applications as it requires minimal space, and it pairs perfectly with switching power supplies for improved efficiency and ripple reduction. This inductor is reliable, with a long life expectancy and excellent heat dissipation due to its shielded casing.

The UP3B-6R8-R inductor works on the principle of self-inductance. When current passes through a conductor, it creates a magnetic field around the conductor. When this flow of current is interrupted, the magnetic field collapses, and a voltage spike is created, which is known as the back electromotive force(EMF). This voltage spike then returns through the conductor again, thus completing the circuit. This phenomenon is known as self-inductance, and it is the working principle of the UP3B-6R8-R inductor.

In summary, the UP3B-6R8-R fixed inductor is a shielded ferrite-core type device used for signal filtering, reducing cross-talk in communication lines, and improving power efficiency and ripple reduction. It has an 8-pin radial lead design, operational temperature range of -40°C to +85°C, rated working frequency of up to 100MHz, inductance range of 1.5uH to 33uH, and a current rating of 2.2A to 6.8A. This inductor works on the principle of self-inductance.
