Resistor offers effective overcurrent protection
A new device offers a cost effective solution for board level overcurrent protection where resettable fusing is unnecessary, and can replace fuse and resistor combinations with a single component
Welwyn Components has a new circuit protection component for low voltage circuitry in instrumentation and consumer applications. Designated the WFF Series, the resistor offers defined safe fusing characteristics together with a range of series resistance values, thus allowing it to perform inrush limiting or EMC filtering functions, as well as fusible protection.
