Wednesday, May 14, 2014: Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of through-hole single-in-line thin film resistors. For high accuracy in precision, high-voltage instrumentation and amplifiers, the Vishay Dale Thin Film HVPS devices feature high resistance values to 10 MΩ, tight tolerances down to ± 0.01 %, and high working voltages to 1800 V.Â
The resistors released today combine their high working voltage with stable film characteristics of ± 0.05 % for 2,000 hours at +70 °C, ultra-low TCR of ± 5 ppm/°C, and a wide resistance range of 50 kΩ to 10 MΩ. Offering a conformal coating, the devices are optimized for high-voltage telecommunication, industrial, and test and measurement applications.Â
HVPS devices feature very low noise of < -30 dB, low thermal EMF of < 0.1 µV/°C, high power ratings up to 400 mW, and a temperature range of -55 °C to +125 °C. Available with lead-bearing and lead (Pb)-free options, the resistors are halogen-free and flame-resistant in accordance to UL 94 V-0.Â
