Advantage Of The RT303 Silver Wire Type Fuse Resistor Link
1.Fast fuse is mainly used for short -circuit protection of semiconductor rectifier elements or rectification devices. Due to the low overload capacity of semiconductor elements. It can only bear a large overload current in a very short time, so short -circuit protection has the ability to fuse quickly. The structure of the fast fuse and the closed fuse of the filler is basically the same, but the melt material and shape are different. It is a transformer melting with a V -shaped deep groove with a silver chip.
2 Broken ability: 1000A (AC 130V);
3 Work temperature range: –40 ℃ ～ 125 ℃;
4 The corresponding relationship between temperature and current is as follows: 3.5 Storage temperature range: –40 ℃ ～ 125 ℃; silver wire fuse requirements and suggestions
5. Direct welding on PCB; generally, the rated current is not more than 90%of the rated current; silver wire distance PCB
The board is small, the sterling silver products are not less than 5mm; the copper silver -plated products are not less than 7mm;
6. The length of the leading lead in the middle should not be less than 12mm; the silver wire fuse is a fuse that belongs to part of the semiconductor component of semiconductor components. Small, and you choose to use silver wire, large current specifications, you need to choose a cross -sectional silver melt to make it. In practical applications, overload protection elements often need to be configured to make the line safer and reliable.
