Inductors are devices that create a magnetic field around an electrical conductor when current is passed through it. A fixed inductor, such as the GLFR2012T101M-LR, is a type of inductor that has a fixed inductance and is usually used to couple two circuits, or in AC/DC power supplies for filtering.

The GLFR2012T101M-LR is a surface-mount fixed inductor with a rated inductance of 1.0 µH and a rated current of 2.2A. It is able to operate up to a temperature range of -40°C to +125°C and is also RoHS compliant. Its small size and surface-mount design make it particularly attractive for applications where space is an issue.

It works by acting as an electromagnetic coupling between two electrical circuits and stores electrical energy in its magnetic field. The current passing through the inductor will generate a magnetic field that will store the energy. When the current is reduced or reversed, the magnetic field will collapse, releasing the stored energy. This effect is what is known as inductive reactance and is important for filtering and coupling purposes.

The GLFR2012T101M-LR is primarily used in two types of applications. The first type is in DC/DC power supplies where it is used for filtering electromagnetic noise and ripple, as well as smoothing out voltage regulation. For this type of application, it is usually placed in series with the power supply and its inductance acts as a low-pass filter that blocks high frequency noise and reduces voltage spikes.

The second type of application is in AC line filters. Here, the inductor is used to filter out noise and unwanted signals that may be present on the AC power line. It is usually placed in parallel with the power line and its inductance acts as a low-pass filter that blocks high frequency noise and reduces voltage hum and spikes.

The GLFR2012T101M-LR surface-mount fixed inductor is a useful device for applications where space is at a premium and signal purity is essential. Its low-profile design and wide operating temperature range make it suitable for a wide range of applications, making it one of the most versatile and popular fixed inductors on the market.
