TT Electronics has launched a new precision Water Insoluble Nitride (WIN) resistor family. The new WIN series thin film chip resistors use an advanced metal film technology to provide extremely high levels of reliability and stability for precision and signal conditioning applications.
The WIN series resistor features a Water Insoluble Nitride film to resist the moisture vulnerability problems of nichrome and passivated nichrome resistor film technologies. Until now this has only been possible using high cost military grade tantalum nitride products. This inherent moisture resistance means users do not need to rely on expensive assembly-level sealing or encapsulation production processes.
The new WIN series also delivers highly stable, predictable life drift and high reliability even in exceptionally humid or polluted environments or in the event of damage to the component’s coating. This is due to its ability to self-passivate by forming a very stable oxide layer, which protects the resistor from moisture failures associated with nichrome resistor films.
Available in 0603, 0805 and 1206 sizes at 0.1W, 0.25W and 0.33W respectively, the series offers resistance values from 10R to 1M0 with a tolerance of +0.1% and TCR of +25ppm/°C. These features combined with sulfur resistant terminations make the WIN series an ideal choice for mission critical applications in harsh environments in medical, aerospace and industrial fields.
