【产品】100%无铅无卤素的表面贴装式快熔保险丝438GT系列,专为150ºC高温电路提供过流保护
LITTELFUSE推出的438GT系列快熔保险丝是100%无铅,无卤素和符合RoHS标准的表面贴装式快熔保险丝,专门设计用于为工作环境温度高达150ºC的电路提供过流保护,具有出色的温度稳定性和性能可靠性。438GT系列快熔保险丝继承了Littelfuse陶瓷保险丝系列中典型的高I²t值,可确保高浪涌电流承受能力。
Littelfuse推出的438GT系列快熔保险丝有2A/2.5A/3A/3.5A/4A/5A/6A共7种不同的额定电流版本可选,其中2~5A的最大额定电压为32V,而6A的版本为24V,在32V/24V直流或12V交流的情况下额定熔断电流为50A。随额定电流的不同,标称电阻值介于0.0086Ω 到0.0490Ω之间,额定电流越大电阻值越小。同样的,I²t值介于0.181A2s 到1.444 A2s之间,额定电流越大I²t值越大。
Littelfuse推出的438GT系列快熔保险丝的主体采用新型陶瓷、焊端采用银镍锡、覆盖涂层采用无铅玻璃制成,100%无铅。潮湿敏感度等级为IPC/JEDEC J-STD-020, Level 1,防潮性通过MIL-STD-202, Method 106标准,端子强度符合IEC 60127-4标准。包装为8mm卷带包装,包装规格EIA-481, IEC 60286, Part 3。
