1KSMB47A Frequently Asked Questions (FAQ)

  • The recommended PCB footprint for the 1KSMB47A is a rectangular pad with dimensions of 0.220 inches (5.59 mm) x 0.140 inches (3.56 mm) with a 0.040 inches (1.02 mm) radius corner. The pad should have a 0.010 inches (0.25 mm) minimum solder mask clearance.

  • The 1KSMB47A has a maximum operating temperature of 150°C, making it suitable for high-temperature applications. However, it's essential to ensure that the device is properly derated to prevent thermal runaway and ensure reliable operation.

  • 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 physical size. Consult the datasheet and application notes for guidance.

  • Yes, the 1KSMB47A is compatible with lead-free soldering processes. Littelfuse Inc. ensures that their products meet the requirements of the RoHS (Restriction of Hazardous Substances) directive.

  • The typical response time of the 1KSMB47A is around 10-20 ms for a 200% overload condition. However, this can vary depending on the specific application and operating conditions.
