27T333C Inductors, Coils, Chokes

Fixed inductors are used in electronic circuits to provide a known, predictable and steady amount of current to a component. Generally, they are composed of one or more windings of wire around a core material. By changing the number of windings, layout and core type, inductance levels can be adjusted to meet circuit demands. Among them, the 27T333C type is one of the most widely used fixed inductors.

The 27T333C is used for low frequency, high current applications. The inductor size is 2.5mm X 3.5mm X 3.3mm and the operating temperature range is -40 to +85℃. It has a hollow cylindrical shape with a lead-free Sn/Cu solder layer, so it can be reliably soldered. The peak temperature does not exceed 230℃and no insulation required. The 27T333C is perfect for mounting directly onto a board, as no secondary processing is needed.

Application Field

27T333C inductors have found widespread use in various applications due to their high performance and low cost. They are used in many electronic circuits, such as switching power supplies, switch mode regulators, filters, resonant circuits and transformers. Their high current and low interference capability make them ideal components for power supply applications. In addition, they are used in palmtops, mobile phones, tablets, car navigation systems and LCD television sets.

Working Principle

The basic principle of 27T333C can be explained as that when an alternating current passes through the inductor, a magnetic field is generated, and the inductor acts as not to allow the strength of the field to change abruptly. The magnetic field generates a reverse current in the inductor, which opposes the source current and provides a necessary delay for the components in the circuit to work properly. This action helps to maintain the flow and maintain a balanced current in a closed loop circuit.

In addition, due to the high power consumption of 27T333C, it is necessary to use inert materials and provide a good cooling system, otherwise it will be easily burned out. The quality of the inductor will directly affect the service life and reliability of the circuit. Typically, a application-specific inductor offers better power conversion efficiency and reduces power loss by creating a difference in the magnitude of current.

Conclusion

The 27T333C fixed inductor is a popular and reliable component for various low frequency, high current applications. It has a small size and can be soldered directly to the board, making it suitable for applications where space is scarce. In addition, its high power efficiency makes it a perfect choice for power supply circuits. Therefore, the 27T333C is fully capable of meeting the requirements of various circuit-level applications.
