Enhanced Pulse Capabilties 1

Shown here is a chart (right) which compares the specified maximum pulse power for RCS series parts versus standard thick film resistor. In this comparison, the single pulse capability chart (top left) found within the Vishay product datasheets, which allow for up to 1000 pulses, were used to make the comparison, considering pulse duration 1 millisecond. As shown, RCS series parts have much higher pulse capabilities compared to the standard thick film of the same size. The RCS0805 can withstand up to 60 watts for this duration compared to only 4 watts allowed for the standard 0805 size part (15 times as much) while the RCS1206 can withstand up to 90 watts compared to only 7.3 watts allowed for the standard 1206 size (12 times as much).
