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.
