Wurth Elektronik provides a recommended PCB layout in their application notes and layout recommendations documents, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, minimal electromagnetic interference (EMI), and reduced radiation.
The selection of the inductor value depends on the specific application requirements, such as the input voltage, output voltage, and current. Wurth Elektronik provides an inductor selection guide and calculation tools on their website, which can help engineers determine the optimal inductor value for their design.
The 82556140 has an operating temperature range of -40°C to +125°C, but it's essential to note that the device's performance and reliability may be affected at extreme temperatures. Engineers should consult the datasheet and application notes for specific temperature-related considerations.
To ensure EMC, engineers should follow Wurth Elektronik's guidelines for PCB layout, component placement, and shielding. Additionally, they should consider using EMI filters, shielding cans, or other EMC mitigation techniques to minimize radiation and susceptibility.
Wurth Elektronik recommends following the JEDEC J-STD-020 standard for soldering the 82556140. Engineers should also consult the datasheet and application notes for specific soldering temperature and time recommendations to ensure reliable assembly.
