Fixed inductors are widely used in electronic circuits due to their low cost but diverse applications. The 1210R-047M is one of the many inductors used in various applications. Before we explore the application fields and working principle of the 1210R-047M, let’s take a look at what an inductor is and what it does.

Primarily, an inductor is an electronic component that stores energy in the form of a magnetic field. An inductor consists of two main types – a coil and a core. The coil is an insulated wire that is wrapped around the core, usually a ferrite material. When a voltage is applied to the coil, a magnetic field is created that induces a current to flow inside the coil. The inductor’s ability to store energy in the form of a magnetic field makes it an ideal component for many purposes such as filtering out high frequency inputs and delaying a current or voltage.

Now let’s move on to the 1210R-047M inductor. This particular inductor is designed for low frequency applications, typically ranging from 100 kHz to 1 GHz. It is a surface-mounted device (SMD) inductor that is made of a monolithic ferrite core with an integral wire-wound coil. It has a rating of 47 µH and a maximum current rating of 300 mA. This particular inductor is used in various applications such as EMI suppression, power factor correction, filters, radio-frequency interference (RFI) suppression, and control loops.

The 1210R-047M works on the same principles as all inductors. When a voltage is applied across the leads of the inductor, a current flow that is proportional to the rate of change of voltage will be induced. Since the rate of change is linear, the current is proportional to the applied voltage. The 1210R-047M also exhibits high resistance to changes in frequency, making it suitable for applications requiring stability over a wide frequency range.

In addition, due to its monolithic design, the 1210R-047M has two valuable characteristics that make it ideal for certain applications. Firstly, it is very compact which makes it suitable for use in applications where space is limited. And secondly, the integral wire-wound coil increases the inductance of the inductor, providing greater stability to the circuit’s operation. This makes the 1210R-047M particularly useful in control loops, where stability is essential.

The 1210R-047M is a versatile and reliable SMD inductor that is used in many applications. It has a low profile, high inductance, and a maximum current rating of 300 mA, making it well suited for many low frequency applications such as EMI suppression, power factor correction, filters, RFI suppression, and control loops. The 1210R-047M utilises the same working principles as all inductors – it converts a voltage to a current – making it a valuable asset in various applications.
