| | | ENGINEERING DATA: RESISTANCE AND TOLERANCES You can select any ohmic value or decimal part of an ohm with tolerances to ±0.005% 10Q min. res. (±0.01%). TCR CHARACTERISTIC Standard: 0±5ppm/°C (100Q and above); 0±15ppm/°C. (values below 100Q) - calculated between +25°C. and +100°C. (Please specify temperature span of operation.) Special: to 0±1 ppm°C. - matching to 0±0.5 ppm°C. POWER VS. AMBIENT TEMP. All Ultra resistors are designed for full load based upon ±1% res. tol. - providing the ambient temp. - plus the temp. rise due to self-heating does not exceed +125°C. Derated to zero power at+145°C. see Fig. 1. STABILITY To ±0.001%/yr. at 25°C. (no load). | | |
