Vishay Intertechnology Inc. (Malvern, PA) released its new thin-film, high-value precision single in-line (HVPS) Series resistors, which offer a resistance tolerance down to ±0.01% over a range of 50 kilohms to 10 megohms. The new HVPS Series of discrete resistors is intended for instrumentation amplifiers and precision voltage dividers in products such as medical and test equipment requiring high precision over a broad resistance range.
The thin-film resistors provide stability of 500 ppm (2,000 hours at +70 °C) and temperature coefficient ratio (TCR) values of 25 ppm/°C, 15 ppm/°C, 10 ppm/°C and ±5 ppm/°C. The HVPS1 is available with a working voltage of 250 V, a power rating of 0.125 W, a resistance range of 50 kilohms to 5 megohms, and dimensions of 0.240 in x 0.260 in x 0.260 in with 0.100 in pin spacing. Rated for a working voltage of 300 V, a power rating of 0.250 W and a resistance range from 100 kilohms to 10 megohms, the HVPS2 measures 0.320 in x 0.260 in x 0.110 in and features a 0.200 in pin spacing.
Samples and production quantities of the new high-value precision resistors are available now, with a lead time of 10 weeks for larger orders. Pricing for US delivery is dependent on resistance value and tolerance, with a typical price of $6.90 per 100 units rated for 5 megohms and ±0.1% tolerance.
