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 W and 6 W in compact 1206 and 2512 case sizes, respectively. The aluminum nitride substrates 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 are said to provide four times the power handling capability of commercial chip resistors, making them appropriate for use in power supplies for industrial, telecommunications, test and measurement, medical, and military and aerospace equipment and instrumentation. PCAN series resistors combine 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 they 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.
