For optimal performance, it's recommended to follow a compact PCB layout with a solid ground plane, and ensure good thermal conductivity by using thermal vias and a heat sink if necessary. A minimum of 1 oz copper thickness is recommended for the PCB.
To select the correct fuse rating, consider the maximum current rating of your circuit, the voltage rating, and the fault current rating. Also, consider the ambient temperature, and the desired response time to faults. Consult the Littelfuse fuse selection guide for more information.
The maximum allowable voltage drop across the CG790MS fuse is 0.5V at the rated current. Exceeding this voltage drop may affect the fuse's performance and reliability.
The CG790MS fuse is designed for general-purpose applications and may not be suitable for high-frequency circuits. For high-frequency applications, consider using a fuse specifically designed for high-frequency circuits, such as the Littelfuse HF series.
To ensure proper soldering, follow the recommended soldering profile, and use a solder with a melting point above 180°C. Apply a small amount of solder to the fuse terminals, and use a soldering iron with a temperature range of 250-300°C.
