大体积***丝7.58*5.5MM2920***丝力特品牌2920L500/16我公司是***生产自******丝集电通，***技术，规格齐全，质量保证，如有特殊规格可以专门定制，型号众多有一些未及时上传，欢迎来电恰询~自******丝是由经过特殊处理的聚合树脂(Polymer)及分布在里面的导电粒子(CarbonBlack)组成。在正常操作下聚合树脂紧密地将导电粒子束缚在结晶状的结构外，构成链状导电电通路，此时的可******丝为低阻状态(a)，线路***经自******丝的电流所产生的热能小，不会改变晶体结构。当线路发生短路或过载时，流经自******丝的大电***生的热量使聚合树脂融化，体积迅速增长，形成高阻状态(b)，工作电流迅速减小，从而对电路进行限制和保护。当故障排除后，PTC可******丝重新冷却结晶，体积收缩，导电粒子重新形成导电通路，自******丝***为低阻状态，从而完成对电路的保护，无须人工更换。2920L***丝，电流从0.3A-5A，力特littelfuse原装，深圳现货，量大可***包邮，只做***！蔡小姐13088852503型号MarkingIhold(A)Itrip(A)Vmax(Vdc)Imax(A)Pdtyp.(W)MaximumTimeToTripResistanceAgencyApprovalsCurrent(A)Time(Sec.)Rmin(Ω)Rtyp(Ω)R1max(Ω)2920L030LF0300.300.6060101.501.503.001.2003.0004.800××2920L050LF0500.501.0060101.502.504.000.3500.8701.400××2920L075LF0750.751.5030401.508.000.300.3500.6701.000××2920L075/60LF075-600.751.5060101.508.000.300.3000.600.950××2920L100LF1001.102.2033401.508.000.500.1200.2700.410××2920L125LF1251.252.5015401.508.002.000.0700.1600.250××2920L150LF1501.503.0033401.508.002.000.0800.1500.230××2920L185LF1851.853.7033401.508.002.500.0500.1100.150××2920L200LF2002.004.0015401.508.005.000.0500.0900.125××2920L200/24LF200-242.004.0024401.508.005.000.0500.0900.125××2920L250LF2502.505.0015401.508.0010.000.0350.0600.085××2920L260LF2602.605.006401.508.0010.000.0250.0500.075××2920L300LF3003.005.006401.508.0020.000.0150.0330.048××2920L300/15LF300-153.005.0015401.508.0020.000.0150.0330.048××2920L500/16LF500-165.0010.0016402.02.005.000.005-0.025××)
