Flameproof metal film resistor offers defined fusing characteristics

Vishay Intertechnology has introduced a new high pulse, non-inductive, fusible, flameproof metal film resistor that meets the safety requirements of UL1412. The Vishay BCcomponents PR02-FS offers defined fusing characteristics at defined overload conditions and resistance values >50ohm to withstand 600V surges (1.2/50µs pulse) as defined by IEC 61000-4-5. With its defined fusing behavior and fast fusing time of <10s for an 80W overload, the device released today is designed to disconnect electronic home appliances such as washing machines and shaver chargers from the power supply. In addition, it 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 device offers a resistance range from 1ohm to 100ohm with tolerance down to ±10%, TCR of ±250ppm/K, rated power dissipation of 2W at +70C, and an operating temperature range from -55C to +200C. Available in a radial version, the device meets active and passive flammability requirements as defined by IEC 60115-1 and UL 94-V0. The resistor is RoHS-compliant, halogen-free, and Vishay Green.
