Caddock USF300 Ultra-Stable Low TC Film Resistors

Caddock USF300 Ultra-Stable Low TC Film Resistors were developed for high-performance analog electronics. Utilizing Caddock proprietary resistance film systems, the Type USF300 resistors provide the lowest TC with a wide resistance range and high voltage ratings.The 300 series boasts a resistance range of 50Ω to 25MΩ with temperature coefficients from -40°C to +85°C (referenced to +25°C), and Zero Nominal TC (maximum absolute TC 5ppm/°C). The resistors' tolerance is ±0.01% or ±0.10%. The USF resistors are constructed with an aluminum oxide ceramic sandwich that provides great thermal conductivity and minimizes the power coefficient drift.
