Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal performance and to prevent damage to the device.
To select the correct current rating, you need to consider the maximum current required by your load, as well as the ambient temperature and the desired temperature rise. Bourns provides a current rating vs. temperature rise graph in the datasheet, which can help with this selection.
Although the datasheet doesn't explicitly state the maximum operating voltage, Bourns recommends that the device be operated within the specified voltage range (12V) to ensure reliable operation and to prevent damage to the device.
The PDB12-H4151-102BF is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If your application requires operation above 125°C, you should consider using a different device or consulting with Bourns' technical support team.
To ensure reliability and longevity, follow proper PCB design and assembly guidelines, use a suitable thermal interface material, and operate the device within its specified ratings. Additionally, consider implementing overcurrent protection and thermal monitoring in your design.
