The Y1625500R000T9R is a 500Ω surface-mount Chip Resistor provides high rated power, excellent load life stability along with extremely low TCR. One of the most 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. It utilizes ultra high precision Bulk Metal® Z-foil. The Z-foil technology provides a significant reduction of the resistive element's sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (power coefficient). Along with the inherently low PCR and TCR, Z-foil technology also provides remarkably improved load life stability, low noise and availability of tight tolerance. It has a full wraparound termination which ensures safe handling during the manufacturing process, as well as providing stability during multiple thermal cycling.
