The Type USF film resistors come in two variations, the 200 series and the 300 series. They were developed to provide a viable option suitable for the requirements for increasing performance for resistors in high performance analogue electronics. They are able to provide the lowest TC with the widest resistance range and the highest voltage ratings available in the market.
Temperature Coefficient -40 to +85 °C, referenced to +25 °C 200 Series - ZERO Nominal TC - Maximum Absolute TC 2 ppm/ °C 300 Series - ZERO Nominal TC - Maximum Absolute TC 5 ppm/ °C
Resistance Range 50 ohm to 25 Megohm Tolerance: ±0.01% or ±0.10% Specific standard resistance values are available that are most commonly required in high accuracy analogue design. These values were selected and optimized for produce ability and performance Ceramic package provides cool operation
