【产品】高达150℃贴片型陶瓷保险丝,专为高工作环境温度电路提供过流保护而设计
保险丝也叫保险丝管,保险丝也被称为熔断器,IEC127标准将它定义为“熔断体”。它是一种安装在电路中,保证电路安全运行的电器元件。当电路发生故障或异常时,伴随着电流不断升高,并且升高的电流有可能损坏电路中的某些重要器件或贵重器件,也有可能烧毁电路甚至造成火灾。若电路中正确地安置了保险丝,那么,保险丝就会在电流异常升高到一定的程度时,自身熔断切断电路,从而起到保护电路安全运行的作用。力特(LITTELFUSE)为广大用户专门设计了大量的贴片型陶瓷保险丝以供选择使用。这种100%无铅,符合RoHS标准和无卤素的保险丝系列专门为高的工作环境温度(高达150℃)的电路提供过流保护而设计。通常设计确保了优异的温度稳定性和性能的可靠性。除此之外,力特(Littelfuse)陶瓷保险丝系列的典型值I2t值保证了高浪涌电流承受能力。
力特(Littelfuse)贴片型陶瓷保险丝系列包括437系列、438系列、440系列、441系列、469系列和501系列。用户可以根据其性能指标和应用场合进行选择。
