產品介紹
描述 :
The next two tables can help the system designer determine specific circuit protection needs in a variety of equipment and identify the PolySwitch devices and part numbers to meet those needs. Follow these steps :
1. Select your equipment type from the first column of the Equipment / Protection Application Table below.
2. Review the protection applications accross the top of the table, nothing than an "X" at the intersection of an application and your equipment type indicates that your equipment requires circuit protection for that application.
3. Use the table on the next page (Protection Application / PolySwitch Surface-Mount Device Selection Table) to select a part number for each application based on your most important design criterion (size, resistance, or time-to-trip).

Raychem的PolySwitch 自复式元件可用于防止电流浪涌、过热造成的损害。像传统的保险丝一样，这些元件可以在故障条件下限制危险的大电流流过。 不过，PolySwitch 元件可以在故障清除和电路电源断开后复位，因此可以减少保修、服务和修理成本。
PPTC元件的典型应用包括计算器和外围设备、可充电电池、电源、汽车电子和电信设备。
