Type TF Low TC Ultra-Precision Film Resistors Absolute TC to 5 ppm/°C, Values from 1 Kohm to 125 Megohms, Absolute Tolerance to ±0.01% Type TF precision resistors employ the Caddock Tetrinox ® resistance films - the resistance system that sets a new standard for high value, ultra-stable precision resistors that provide an exceptional combination of performance characteristics: • Ultra-Precision - Five standard resistance tolerances from ±1% to ±0.01%. • A Wide Range of Resistance Values - from 1 Kohm to 125 Megohms. • Low Temperature Coefficient - 5 ppm/°C, 10 ppm/°C, or 15 ppm/°C. • Long-Term Stability - to 0.01% per 1,000 hours. This approach to quantity production of ultra-precision discrete resistors is the result of combining our unique complex oxide resistance film technology with an advanced high thru-put laser manufacturing capability.
