PA4548.681NLT

Fixed inductors are essential components in the design of an electronic circuit. These components rely on the principles of inductance to perform their functions in a variety of different ways. The PA4548.681NLT is one such device, and its application field and working principle are as follows.

Application Field

The PA4548.681NLT is able to handle electrical currents up to 8A and voltage as high as 400V/8A. The device is designed for use in switching power supplies, motor controls, and other applications requiring higher currents. It is capable of providing high stable inductance values with low RMS current. As a result, it is ideal for applications involving switching regulators, DC-DC converters, and other power electronics applications.

Working Principle

The principle of operation of the PA4548.681NLT is based on the principle of inductance. An alternating current passing through a coil of wire induces a magnetic field which is proportional to the current flowing through the coil. This magnetic field then induces an electrical current in the neighboring coil. This induced current is in the opposite direction to the original current and is known as counter-electromotive force. This force causes the current to decrease and therefore acts as a damping effect on the original current. As a result, the PA4548.681NLT is capable of providing stable inductance along with low RMS current.

The PA4548.681NLT is constructed using ferrite core material for increased saturation current and a shielded enclosure for better protection from external interference. The device has a wide operating temperature range, from -25℃ to +85 ℃, and is also highly reliable, featuring a maximum lifetime of 50000 hours at 85℃.

In summary, the PA4548.681NLT is a high quality fixed inductor designed for applications requiring higher current. It has a wide operating temperature range, and is highly reliable and suitable for high current applications. As such, it is a valuable component for power electronics designs.
