thin film chip resistorVishay 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
  • Laser-trimmed tolerances down to ± 0.1 percent over a wide temperature range of -55 °C to +150 °C. .
  • A wide range of resistance values from 30 Ω to 175 Ω.
  • Low noise of < -30 dB.
  • Low voltage coefficients of 0.1 ppm/V.
  • Voltage ratings from 75 V to 200 V.
