RWS7 & RWS10 SMD Resistors

Ohmite RWS7 and RWS10 Precision Power Wirewound SMD Resistors are designed to meet the rising power requirement for surface mount components. The RWS7 and RWS10 series resistors from Ohmite have an optimized thermal design that offers greater efficiency and improved surge capacity of up to five times for five seconds while reducing the rise of surface temperature when compared with other resistors. These RoHS-compliant PCB mount resistors have been engineered to reduce long-term thermal damage to boards and surrounding components. RWS7 and RWS10 SMD resistors are also available in a low-inductance format.
