0306 Size Terminal Resistor Handles 0.5W

KOA Speer Electronics’ WK73R1J thick-film wide terminal resistors feature a 0.5W power rating in a 0306 package. The component achieves a high power rating of 0.5W via a reverse-geometry design, which provides for greater heat dissipation. Additionally, it offers reliable thermal-shock characteristics and solder-joint resistance, and an operating temperature of -55°C to +155°C. Other features include a TCR of ±100 ppm/°C with resistance tolerances of 1% and 5%, resistance values of 10Ω to 1MΩ and AEC-Q200 qualification. Lead time is 10 weeks and samples are available upon request.
