The minimum ohmic value is now halved to 5 ohms, and a tolerance of ±0.05% and TCR of ±15ppm/°C is now included. In addition, WIN is now available with optional SnPb terminations, allowing its use in high reliability designs where RoHS termination finishes are not required. This represents the first in a series of planned extensions to the range of products available on the WIN platform.
TT Electronics’ Water Insoluble Nitride (WIN) series precision chip resistors use tantalum nitride technology to solve the moisture vulnerability problems of nichrome and passivated nichrome resistor film technologies. Previously, this high reliability solution was only available in military and aerospace related components but investment in a state of the art, lean process has enabled TT Electronics to deliver the same benefits to the industrial, medical and IT markets.
One recent example application is in the design of power supplies for mainframes and servers. The need to guarantee high availability of these systems places particular demands on the reliability levels of all components including passives. However commercial competitive pressures make the use of screened components unsustainable. This is where WIN offers design solutions that provide industry leading moisture resistance performance at an acceptable price point.
