Fixed Inductors

Inductors are components that store energy in magnetic fields. They are used in circuits to block DC current while allowing AC current to pass. By controlling the amount of electrical current through a circuit, they help to produce or suppress oscillations. Fixed inductors are inductors that have a fixed inductance value. They are usually preferred for circuits with a fixed voltage, such as DC and AC power supplies.

NRS8030T330MJGJ Application Field and Working Principle

The NRS8030T330MJGJ is a fixed inductor from TDK-Lambda. It has a nominal inductance value of 330 μH and can handle up to 8.5 A. It is ideal for AC-DC and DC-DC power supplies, as well as for circuit applications with narrow bandwidths. Its operating temperature range is -40°C to 105°C and its rated ambient temperature is 85°C. The NRS8030T330MJGJ is rated for use up to 3000 VAC and carries an insulation strength rating of 1000 VAC.

The working principle of the inductor is that it stores energy inside a magnetic field created by the passing current. Upon application of a sudden voltage change, the inductor will be slow to react, producing an output voltage that lags behind the input voltage. This phenomenon is known as inductive reactance. The inductance of an inductor is determined by the number of turns of wire per coil, the cross-sectional area of the coil, and material of the core. The NRS8030T330MJGJ has an air core and 33 turns per coil, providing it with its 330 μH inductance.

In addition, the NRS8030T330MJGJ is part of TDK-Lambda’s Magnetically Shielded Fixed Inductors Series. This series is designed to reduce emissions of noise from the inductor, helping to protect nearby sensitive components from interference. The inductors in the series utilize multiple magnetic shields consisting of non- conducting epoxy resin and ferrite cores. This helps to reduce magnetic fields by 90%.

To summarize, the NRS8030T330MJGJ is a fixed inductor operating in the range of 8.5 A with an inductance of 330 μH. It is a suitable component for circuits requiring narrow bandwidths and can handle high voltages. It is also shielded to protect nearby components from noise interference.
