Image of Vishay CRCW-HP pulse-proof high-power thick-film chip resistors - power rating

This slide compares continuous power dissipation ratings of CRCW-HP series parts with those of standard thick-film resistors of the same size in further detail. As shown in the chart here (top), CRCW-HP series parts are specified to withstand continuous power dissipation of up to three or four times that allowed for standard thick-film chip resistors of the same size. For example, while a standard 0805 size thick-film chip resistor may only dissipate 0.125W, the CRCW0805-HP handles up to 0.5W (4 times as much). The CRCW-HP series is also offered as a 0 Ω resistor, also known as a “jumper”. CRCW-HP series jumpers offer vastly increased current capabilities compared to standard jumpers as shown in the chart above on the bottom. For example, the 1218 size CRCW-HP jumper withstands 20A continuously versus 7A that the standard 1218 jumper withstands (nearly 3 times as much).
