Compact New Vishay Intertechnology Surface-Mount Precision Thin Film Chip Resistors, Built on Aluminum Nitride Substrates, Deliver Power Ratings Up to 6 W

Vishay » PCAN

Vishay Intertechnology introduced a new series of high-power, surface-mount precision thin film chip resistors. Built on aluminum nitride substrates, PCAN series devices offer power ratings of 2 W and 6 W in compact 1206 and 2512 case sizes, respectively. 

Vishay PCAN

The aluminum nitride substrates of the Vishay Dale Thin Film resistors released today feature enlarged backside terminations to reduce the 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 for industrial, telecommunications, test and measurement, medical, and military and aerospace equipment and instrumentation.

PCAN series resistors 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. The devices are offered with a wide range of resistance values from 30 Ω to 175 Ω, and offer low noise of < -30 dB, low voltage coefficients of 0.1 ppm/V, and voltage ratings from 75 V to 200 V. Flame-resistant in accordance with UL 94 V-0, the resistors' wraparound terminations are lead (Pb)-free and RoHS-compliant, with lead (Pb)-bearing, wire bondable gold, and epoxy bondable (glueable) gold terminations available.
