Littlefuse的JLLS系列保险丝提供无镀层和镀银两种端接方式。
有镀层和无镀层保险丝之间的主要区别在于镀银，它有助于防止腐蚀。这二者在电气性能方面的功能是相同的，但镀银有助于提高保险丝在腐蚀性环境中的耐用性。
在选择保险丝时，需要考虑的关键因素包括：
-
保险丝尺寸：为了确保保险丝能够承受潜在的浪涌电流，需要对最大运行（稳态）电流取用安全系数。
例如，将最大运行电流乘以1.25 可以得到适当的保险丝额定值。（向上取整到最接近的标准保险丝尺寸）
在选择保险丝时，还应考虑系统的其他物料，如断路器。断路器厂商需要提供这方面的指导，因为他们在进行协调测试会同时使用保险丝。 -
用于电机保护的时滞保险丝：电机系统（尤其是液压电机等具有高感抗的电机系统）需要时滞保险丝来处理启动浪涌。
快速熔断保险丝可能会因感性负载冲击电流而过早断开。
选择保险丝时不仅要匹配电气额定值，还要考虑系统电感、断路器协调和电机保护。对于感性负载，时滞保险丝是最佳选择。
