Vishay Intertechnology, Inc. 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 and 6 W in compact 1206 and 2512 case sizes, respectively.
The aluminum nitride substrates of the Vishay Dale Thin Film resistors released 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 percent over a wide temperature range of -55 to +150 °C. The devices are offered with a wide range of resistance values from 30 to 175 Ω, and they offer low noise of < -30 dB, low voltage coefficients of 0.1 ppm/V, and voltage ratings from 75 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.
Samples and production quantities of the PCAN series devices are available now, with lead times of eight weeks for large orders. Pricing for U.S. delivery starts at $0.75 per piece in 1,000-piece quantities and varies by case size, TCR, and tolerance. Visit www.vishay.com for more information.
