Y174550R0000T9R Datasheet PDF - Vishay Foil Resistors

●The Y174550R0000T9R is a 50Ω 250mW surface-mounting ultra high precision Chip Resistor utilizes ultra high precision Bulk Metal® Z-Foil technology. It offers all the elements of precision including low TCR, tight tolerance, long term stability and low noise, low thermal EMF and non-measurable voltage coefficient. One of the important parameters influencing stability is the temperature coefficient of resistance (TCR). Although, the TCR of foil resistor is considered extremely low, this characteristic has been further refined over the years. The Z-foil technology provides a significant reduction of the resistive elements sensitivity to ambient temperature variations (TCR) and to self heating when power is applied.
