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%.
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.
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.

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 configuration
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.
