100-681H

Fixed inductors consist of two coils of insulated wire wrapped around a core material – usually an iron core. The core material is generally nonconductive meaning that there is a negligible amount of resistance to the flow of current between the two coils. The core material provides a path for the current to take from one coil to the other, allowing them to be connected in series or in parallel, and it also provides an inductance, which is the basic property that defines the characteristic of the inductor. The inductance of a fixed inductor is directly proportional to the size of the core and the number of turns on the coil. The larger the core will provide more inductance than the smaller core.

The 100-681H is an example of a fixed inductor and is designed for a wide range of applications. It is an axial inductor with an internal dimension of 4 x 3 mm and a nominal value of 680 nH. The operating temperature range is -25°C to +85°C and the rated current is 0.45 A. It is available in both through-hole and surface-mount packages.

The 100-681H has a wide range of potential applications. The most common application is in power-line filters, which are used to reduce disturbances and noise in power circuits. They are also widely used for radio frequency interference (RFI) attenuation and noise reduction in telecommunications devices, computers, and other electronic devices. In addition, fixed inductors are used in switching power supplies to provide filtering of the output voltage, as well as in DC-DC converters, so that the output voltage is filtered and free from spikes and noise.

The working principle of the 100-681H is as follows: when the input current flows through the core material, it creates an opposing magnetic field. As the current changes direction, the opposing magnetic field stored in the core induces a voltage in the wire that reverses the direction of the current. This causes the current to flow in the opposite direction which further increases the opposing magnetic field, creating a loop which filters out noise and other disturbances in the circuit.

In summary, the 100-681H is a fixed inductor with an internal dimension of 4 x 3 mm and a nominal value of 680 nH. Its wide range of potential applications include power-line filters, radio frequency interference (RFI) attenuation, noise reduction, switching power supplies, DC-DC converters, and other electronic uses. Its working principle is based on the principle of magnetic induction, where the opposing magnetic field stored in the core induces a voltage in the wire that reverses the direction of the current, thus creating a loop that filters out noise and disturbances.
