1W电流检测电阻器1W current sensing resistors
➀ Rhopoint Components代理VPG Foil Resistors的1W表面贴装电流检测电阻（RBF系列），阻值范围0.01Ω至1Ω，公差低至0.5%；
➁ 该电阻温度系数为±25ppm/°C（0.1-1Ω型号可升级至±10ppm/°C），在+70°C内可满功率运行，采用金属基板散热可提升至2W功率；
➂ 主要应用于太阳能逆变器、风电监测、电源系统及过流保护电路等领域。
➀ Rhopoint Components is distributing 1W surface-mount current sensing resistors (RBF series) from VPG Foil Resistors, with resistances ranging from 0.01Ω to 1Ω and tolerances as low as 0.5%;
➁ The resistors feature temperature coefficients of ±25ppm/°C (expandable to ±10ppm/°C for 0.1-1Ω variants) and can operate at full power up to +70°C, with cooling solutions like metal PCBs enabling higher performance;
➂ Designed for applications in solar inverters, wind power monitoring, power supplies, and over-current detection circuits.
