Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize electromagnetic interference, and optimize the overall performance of the inductor.
The 91A1A-B28-A23L is designed to operate at high frequencies, but its behavior under high-frequency switching conditions depends on the specific application and circuit design. Engineers should consult Bourns' application notes and simulation models to ensure the inductor meets their specific requirements.
The maximum allowable current for the 91A1A-B28-A23L is specified in the datasheet, but engineers should also consider the inductor's temperature rating, which is affected by the current flowing through it. Bourns provides thermal derating curves to help engineers determine the maximum allowable current at a given temperature.
The 91A1A-B28-A23L has a maximum operating temperature rating of 125°C. While it can be used in high-temperature environments, engineers should consider the inductor's thermal derating, which may affect its performance and lifespan. Bourns provides guidance on high-temperature operation in their application notes.
The 91A1A-B28-A23L uses a ferrite core material, which is optimized for high-frequency operation. While the ferrite core material is designed to minimize core losses, engineers should still consider the potential for core losses, especially at high frequencies. Bourns provides guidance on core losses and how to minimize them in their application notes.
