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 Coefï¬cient - 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 ï¬lm technology
with an advanced high thru-put laser manufacturing capability.

Custom Type TF Resistors
Additional cost savings can be
realized when your high volume
ultra-precision Type TF
resistor is optimized for:
⢠Lightning transient capability
⢠Voltage rating
⢠Power rating
⢠Mechanical conï¬guration
⢠Ratio matched sets
And for special requirements, custom
Type TF resistors are available with:
⢠TC of 5 ppm/°C, 10 ppm/°C, 15 ppm/°C,
20 ppm/°C, or 25 ppm/°C.
⢠Shelf stability of 0.0025% per year.
Type TF resistors can also be produced
with custom-spaced radial leads that will
plug directly into your existing circuit
layout.
