PCNM www.vishay.com Vishay Dale Thin Film High Power Aluminum Nitride, Wraparound Surface Mount, Precision Thin Film Non-Magnetic Chip Resistor (up to 6 W) FEATURES High thermal conductivity aluminum nitride substrate Power rating up to 6.0 W Resistance range 2 to 30.1 k Resistor tolerance to 0.1 % TCR to 25 ppm/C Flame resistant UL 94 V-0 APPLICATIONS Power supplies Power switching PCNM series chip resistors are designed on aluminum nitride ceramic substrates with enlarged backside Braking system terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end users TYPICAL PERFORMANCE circuit assembly. Actual power handling capability is limited by the end user ABSOLUTE mounting process. As with any high power chip resistor the ability to remove the heat is critical to the overall TCR 25 performance of the device.
