The PR02-FS offers a resistance range from 1Ω to 100Ω with tolerance down to ±10% and rated power dissipation of 2W at 70°C.
Vishay Intertechnology has rolled out a new high pulse, non-inductive, fusible, flameproof metal film resistor that meets the UL1412 safety requirements. The Vishay BCcomponents PR02-FS offers defined fusing characteristics at defined overload conditions and resistance values >50Ω to withstand 600V surges (1.2/50µs pulse) as defined by IEC 61000-4-5, according to the company.
The device, which features a defined fusing behaviour and fast fusing time of <10s for an 80W overload, is designed to disconnect electronic home appliances such as washing machines and shaver chargers from the power supply. It also provides current limiting in low voltage power supplies for indoor lighting applications. Moreover, due to its inherent non-inductive design, it can be used in applications such as snubber circuits with inductive loads.
The PR02-FS offers a resistance range from 1Ω to 100Ω with tolerance down to ±10%, TCR of ±250ppm/K, rated power dissipation of 2W at 70°C and an operating temperature range from -55°C to 200°C. Available in a radial version, the device meets active and passive flammability requirements as defined by IEC 60115-1 and UL 94-V0.
Samples and production quantities of the RoHS-compliant and halogen-free PR02-FS are available now, with lead times of 8 to 10 weeks for large orders.
