±1% Resistance Tolerance is Standard - tolerances to
±0.1% are available on special order.
Operating Temperature - from -55°C to +175°C.
Full Power Rating at +125°C.
Temperature Coeffi cient is ≤ 50 ppm/°C from
5 ohms to 5 Megohms and ≤ 80 ppm/°C up to
100 Megohms - referenced to +25°C with the ΔR taken
at -15°C and +105°C.
Extended Life Stability is Typically Better Than 0.1%
per 1,000 Hours.
Caddock's Non-Inductive Performance - provides faster
settling times and minimum distortion in all types of high
frequency circuits.
