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 management and to prevent thermal runaway.
To select the correct fuse, consider factors such as the maximum current, voltage, and power rating of your circuit. You should also consider the fuse's response time, interrupting rating, and agency approvals (e.g., UL, IEC). Bourns provides a fuse selection guide on their website to help with this process.
The derating curve for the PTL45-15O0-104B1 can be found in the datasheet or in Bourns' application note AN164. The curve shows the maximum allowable current at different ambient temperatures, helping you to ensure safe operation and prevent overheating.
The PTL45-15O0-104B1 is designed to meet the vibration requirements of IEC 60068-2-6, which includes vibration testing up to 10 G. However, it's essential to evaluate the specific vibration requirements of your application and consider additional testing or design modifications if necessary.
Bourns recommends a soldering profile with a peak temperature of 260°C (500°F) and a dwell time of 10-30 seconds. It's essential to follow a controlled soldering process to prevent damage to the fuse and ensure reliable operation.
