Vishay Intertechnology Inc. introduced a new series of high-power, surface-mount, precision non-magnetic thin film chip resistors. Built on aluminum nitride substrates, the Vishay Dale Thin Film PCNM series offers power ratings of 2 W and 6 W in compact 1206 and 2512 case sizes, respectively. The aluminum nitride substrates of the 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 previous-generation non-magnetic resistors. These high power ratings make the devices ideal for use in power supplies for telecommunications, medical, and military equipment and instrumentation. The resistors non-magnetic properties eliminate the effects of stray magnetic fields on circuit performance in X-ray and MRI machines while correcting passive inter modulation issues in cell phone base stations and amplifiers. PCNM series devices combine their high power ratings with a low TCR down to ± 25 ppm/°C and laser-trimmed tolerances to ± 0.1% over a wide temperature range of -55°C to +155°C. The resistors are offered with a wide range of resistance values from 2 O to 30.1 kO, 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. Samples and production quantities of the PCNM series are available now, with lead times of eight to 10 weeks for large orders.
