Littelfuse recommends a PCB layout with a large copper area for heat dissipation, and a thermal pad connected to a heat sink or a metal plate. A minimum of 2 oz copper thickness is recommended. Additionally, ensure good airflow around the device to prevent overheating.
To select the correct fuse rating, consider the maximum current and voltage ratings of your circuit, as well as the fault current and energy let-through requirements. Consult the Littelfuse fuse selection guide or contact their technical support for assistance.
The CG7250MS has an operating temperature range of -40°C to 125°C. However, the fuse's melting I²t and fault current ratings are derated above 85°C. Consult the datasheet for specific derating curves.
Yes, the CG7250MS is designed to withstand high-vibration and high-shock environments. However, ensure proper PCB mounting and secure the device to prevent movement or damage. Consult Littelfuse's vibration and shock testing standards for more information.
Follow Littelfuse's recommended soldering profile and ensure the PCB is clean and free of oxidation. Use a solder with a melting point above 180°C, and apply a soldering iron with a temperature range of 250°C to 300°C. Avoid excessive soldering time and temperature to prevent damage to the fuse.
