【产品】被设计用于过流保护的两款超小型延时保险丝804、807系列
804、807系列是LITTELFUSE(力特)公司推出的两款超小型延时保险丝,被设计用于过流保护。804、807系列延时保险丝底座和端子帽均采用棕色热塑性聚酰胺材料,满足UL 94V-0阻燃等级。并且由于两者I2t值高,因此具有良好的抗浪涌特性,可用于电池充电器、消费类电子产品和电源等方面。
图1 804、807系列延时保险丝产品图
电气特性方面,804、807系列延时保险丝能够承受的电压最大值分别为250VAC和300VAC,额定电流值都在0.80A~6.30A,并且804、807系列分别具有最大150A和100A的分断额定电流值。在125%的额定电流下,两款保险丝至少能正常工作3600秒;在200%的额定电流下,其最多能工作120秒;在1000%的额定电流下,其最多能工作1秒。此外,两款产品工作温度范围广(-40~+125℃),较宽的温度范围能保证器件稳定性。
804、807系列延时保险丝产品特性:
无铅、无卤、符合RoHS标准
减少了PCB空间需求
直接焊接或插入式形式
低内阻
防电击外壳
抗振动
由于I2t值高,因此具有良好的抗浪涌特性
