1、超出额定范围或不正确地使用PPTC元件都可能导致产品的损坏,并可能导致电弧和火焰;

/Use PPTC exceed by the maximum rating and improper use may result in device damage and possible electrical arcing and flame.

2、PPTC元件一般只用于偶然的过流或超温故障时的保护,切勿用于故障频繁发生或预期会发生长时间故障的 场合;

/PPTC are designed for protection against over current or temperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated.

3、如果不按照建议安装、测试和使用产品,元件性能可能会受到不利影响;

/Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components.

4、在电感强度大的电路中使用时,可能会产生超过PPTC元件的额定电压的回路电压;

/Use PPTC with a large inductance in circuit will generate a circuit voltage above the rated voltage of the PPTC.

5、PPTC元件应用时不能长期处于压力下,使其缺乏膨胀空间而影响其性能,如处于高压或安装在受限的狭小 空间里. /Avoid impact PPTC device its thermal expansion like placed under pressure or installed in limited space.
