UP2.8B-330-R

Fixed inductors have integral roles in many circuitry and electrical systems. The UP2.8B-330-R is one such type of device, found in most applications involving radio frequencies, and power supply circuits. This article will discuss the application field and working principle of the UP2.8B-330-R.The UP2.8B-330-R is an inductor designed for use in high frequency (> 10MHz) radio applications. It is made of a 94% nickel core with a flat, 2.8 mm diameter coil of fine wire. The shape of the coil minimizes the amount of stray magnetic fields produced thereby decreasing unwanted interference. The inductance of this device is typically around 330μH, and it is generally expected to handle currents up to 0.7 Amps.When used in radio receivers, the UP2.8B-330-R is positioned so that the coil sits directly between the antenna and the radio receiver circuit. This allows the inductor to intercept any incoming radio signals, such as those from the antenna. As this signal passes through the inductor, it experiences a change in voltage and current levels due to an electromagnetic phenomenon known as induction. This means that the output voltage and current will be different to the input voltage and current.Next, the voltage and current levels will pass through the radio receiver\'s tuned circuit. This is a type of circuit which is tuned to only allow certain frequencies to pass through while filtering out all the others. The UP2.8B-330-R can be adjusted to provide a better response for specific frequencies.On the other hand, when used in power supply circuits, the UP2.8B-330-R performs an equally vital role. As the current moves through the coil, an electrical flow is generated which creates an opposing magnetic field. This opposes the progression of the current, allowing for a much smoother change in voltage as it passes through the circuit. This type of inductor also helps to filter out any spikes, surges and noise which may result due to the switching of component within the circuit.In summary, the UP2.8B-330-R is an RF inductor with a flat, 2.8 mm diameter coil. It is used in radio applications to intercept incoming radio signals, while also being deployed in power supply circuits to filter out any noise. Its inductance is typically around 330μH, and it can handle up to 0.7 Amps of current.
