Part Details for CG21000LSTR by Littelfuse Inc

For optimal thermal performance, it is recommended to use a thermal pad on the bottom of the device and connect it to a large copper area on the PCB. This helps to dissipate heat efficiently. Additionally, keeping the PCB traces and vias away from the thermal pad can improve thermal performance.

To select the correct fuse, consider factors such as the maximum current rating, voltage rating, and interrupting rating required for your application. You should also consider the fuse's melting I²t, cold resistance, and operating temperature range. Consult the datasheet and application notes for guidance.

The CG21000LSTR is a high-speed fuse with a fast acting characteristic, making it suitable for high-reliability applications. It has a higher interrupting rating and a faster response time compared to other similar fuses. Check the datasheet and compare the specifications to determine the best fit for your application.

The CG21000LSTR is rated for operation up to 125°C. However, the fuse's performance and reliability may be affected at high temperatures. Consult the datasheet and application notes for guidance on using the fuse in high-temperature environments.

To ensure proper soldering, follow the recommended soldering profile and use a solder with a high melting point. Apply a small amount of solder to the PCB pad and component lead, and use a soldering iron with a temperature range of 250°C to 300°C. Avoid applying excessive heat or force, which can damage the fuse or PCB.
