Vishay – New PCAN Series of Surface-Mount Precision Thin Film Chip Resistors
Thin Film PCAN high-power surface-mount precision thin film chip resistors are based on an aluminum nitride substrate. The devices feature enlarged backside terminations to reduce thermal resistance between the topside resistor layer and the solder joint on the end user’s circuit assembly. As a result, the devices provide four times the power handling capability of commercial chip resistors, making them ideal for use in power supplies in a wide range of equipment and instrumentation. The devices combine their high power ratings with a low TCR of ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 % over a wide temperature range of -55 °C to +150 °C.
- Provide four times the power handling capability of commercial chip resistors
- Enlarged backside terminations reduce thermal resistance
- Wraparound terminations are lead (Pb)-free and RoHS compliant, with lead (Pb)-bearing, wire bondable gold, and epoxy bondable (glueable) gold terminations available
