High Power Aluminum Nitride, Wraparound Surface Mount,

Precision Thin Film Non-Magnetic Chip Resistor (up to 6 W)

PCNM series chip resistors are designed on aluminum

nitride

ceramic

substrates

with

enlarged

backside

terminations to reduce the thermal resistance between the

topside resistor layer and the solder joint on the end users

circuit assembly.

Actual power handling capability is limited by the end user

mounting process. As with any high power chip resistor the

ability to remove the heat is critical to the overall

performance of the device.

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

• Braking system
