Fixed inductors, also known as coils or chokes, are energy storage devices used in many different types of circuits. SP1812R-103K is a type of fixed inductor made of metal alloy or special organic materials. This type of inductor is designed specifically to provide a relatively high inductance in a very small package. As such, it is ideal for applications requiring low profile, low/no EMI or high-frequency in small spaces such as mobile and wearable devices, space constrained automotive, industrial, consumer electronics, military, and medical devices.

The SP1812R-103K is an SMD Inductor consisting of a magnet core and inductor winding conduction. The core helps increase the inductor-coil field forms a magnetic loop, which in turn creates energy to be stored when electricity passes through. This stored energy creates a voltage drop that counteracts the original current, resulting in less power dissipation and reduced noise.

One of the most common applications of SP1812R-103K is for switching power supplies. It provides a stable electrical input even when the input voltage changes. This is important when designing power supplies that may be used in environments that suffer from frequent changes in voltage, as it helps maintain a steady power flow to electronic components. It can also be used in electronic filter circuits, filtering out high-frequency or unwanted signals.

The SP1812R-103K is also suitable for other types of applications, including RFID, telecommunications, and automotive electronics. It is designed to reject external interference from excessive noise or electromagnetic fields, making it ideal for use in sensitive applications. It can also be used in loudspeakers, amplifiers, and other audio circuits that require a low-noise signal with a flat frequency response.

Given its small size and high performance, the SP1812R-103K is a great choice for applications that require a reliable fixed inductor. It is designed to provide a stable electrical input even when voltage changes, making it suitable for power supplies and audio applications. Its small form factor makes it ideal for space-constrained automotive, military, and medical devices, while its rejection of external interference makes it suitable for sensitive applications such as RFID and telecommunications.
