Fixed inductors are passive electrical components, consisting of an insulated wire, which is wound around a core of magnetically-conductive material, with the wire\'s ends then connected to two leads. Inductors are primarily used in power supply circuits, to store energy temporarily, and in AC filtering circuits. The T1812-1R8J is specifically designed and manufactured to deliver advanced performance in a variety of specialized applications.

The T1812-1R8J is a high-current, space-saving 12.5mH inductor with self-heating properties of 0.11 °C/W. It is RoHS-compliant and UL recognised, and is fully compatible with the EU Directive 2002/95/EC. Its rated current is 1.8A, and it has an inductance of 12.5mH ±20%, and a Q value of 30. Other features include low self-heating of 0.11 °C/W, compact size, and an operating temperature of - 40°C to + 155°C. It is also highly regarded for its high current capabilities, as well as its low voltage absorption rate which helps to reduce EMI noise.

The T1812-1R8J is designed for use in a wide range of applications including switching mode power supplies, adjustable voltage regulator modules (VRM), AC adapters, battery chargers, DC-DC converters, notebook PCs, and other portable electronic devices. In these applications, the component is used to inductively store energy, allowing the circuit to increase or decrease voltage levels, stabilize voltages, and regulate the amount of current passing through the device. When used in such circuits, the inductor\'s core material works to magnetically convert AC energy into DC energy, and the winding then acts to transform DC energy into AC energy. This allows the inductor to act as a filter, allowing the circuit to easily adjust current and voltage levels.

When working at high currents, the T1812-1R8J inductor also helps to reduce its temperature, due to the reduced magnetic material core. This helps to reduce the possibility of electric shorts and extending the lifespan of the component. In these applications, the inductor can also help to protect sensitive circuits from dangerous voltage spikes, which can damage or destroy the components. Additionally, it helps to reduce EMI noise that can otherwise be created due to the connections to sensitive components.

The T1812-1R8J fixed inductor is specifically designed and manufactured to deliver extraordinary performance in a wide range of specialized applications. It is highly regarded for its high current capabilities, low temperature rise, low voltage absorption rate, and low EMI noise. Additionally, it is RoHS-compliant, UL recognised, and fully compatible with the EU Directive 2002/95/EC, making it an excellent choice for engineers and designers alike.
