Fixed inductors play an important role in many applications such as power supplies, filtering and resonant circuits, as well as providing a means of impedance matching. The LTF4022T-470M-D is one example of such an inductor that is designed to meet the demands of high power applications.

The LTF4022T-470M-D is a high-power inductor that features a molded package with an extended temperature range. This device offers a stable inductance value over a wide temperature range of -40°C to +150°C, as well as excellent high temperature performance and reliable mechanical durability.

The body of the LTF4022T-470M-D is made of metal alloy and features a two-layer metallic construction with an iron core and a copper winding. This construction helps provide a high level of magnetic shielding that improves efficiency by reducing losses due to leakage field. The inductor also includes a plastic sleeve inside the metal housing to improve electrical insulation and enhance durability.

The LTF4022T-470M-D comes with a standard inductance value of 470 μH, but it also comes with the option of customizing the inductance value. Its rated current is 3.2A, and its highest operating temperature is 150°C. The inductor has a low DC resistance of 0.32Ω, making it suitable for use in power applications.

The LTF4022T-470M-D also features a self-healing effect that reduces susceptiblity to thermal runaway. This feature allows the inductor to self-repair in the event of an overcurrent situation by rapidly reducing the inductance while gradually increasing the resistance of the coil. This helps to maintain a safe and stable operation of the device.

The LTF4022T-470M-D is a popular choice for power supply and filtering applications due to its high inductance value and high current rating. These characteristics allow the inductor to be used in boost and buck/boost DC-to-DC converters, allowing it to handle a wide range of supply voltages and providing high-efficiency conversion. The inductor can also be used in common-mode noise suppression circuits for telephone and computer systems.

The LTF4022T-470M-D is an indispensable part of many power supply, filtering, and noise suppression applications due to its high power rating, wide operating temperature range, excellent temperature performance, and reliable mechanical durability. Its self-healing feature also contributes to its robust performance in both high current and high temperature applications.
