TF020N
TF020N is Low TC Ultra-Precision Film Resistors manufactured by Caddock.
Type TF Low TC Ultra-Precision Film Resistors
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 bination 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 bining our unique plex oxide resistance film technology .. with an advanced high thru-put laser manufacturing capability.
