Type TN Lab Grade Low TC Precision Film Resistors

    Type TN Lab Grade Low TC Film Resistors were specifically 

developed  for  use  in  0°C  to  +70°C  applications  which  require  a 

low  temperature  coefficient  and  a  high  degree  of  precision.  

These  resistors  combine  the  outstanding  characteristics  of 

Caddock's  Tetrinox®  resistance  system  with  a  space  efficient, 

non-inductive,  radial-lead  design.    These  resistors  are  intended 

for precision analog designs where the system is not exposed to 

full military or space grade operating conditions.  For full military 

or  space  grade  operating  conditions, we  recommend  Caddock's 

Type  TK  Low  TC  Precision  Radial-Lead  Film  Resistors.

    For 

lab grade applications which require higher voltage ratings (up to 

1,400 volts) and power ratings (up to 0.75 Watt), we recommend 

Caddock's 

Type TF Low TC Ultra-Precision Film Resistors

.

    The performance features of the Type TN Lab Grade Low TC 

Precision Film Resistors are:

 

Low Temperature Coefficient

 - 5, 10, or 20 ppm/°C.

 

Ultra-Precision

 - Tolerances from ±0.025% to ±1%.

 

Resistance Range

 - from 1 K to 1 Meg.

 

Non-Inductive Design

.

 

Radial-Lead Design

 - conserves board space.

Low TC of 5 ppm/°C, 10 ppm/°C, or 20 ppm/°C from 0°C to +70°C
