Vishay – TNPW and TNPU Series: TNPW/TNPU High Stability and Precision Thin Film Chip Resistor

The TNPW and TNPU thin film series from Vishay are an excellent choice where precision and long term stability are required.

These thin film series have Vishay’s special passivation method to provide the component with superior moisture resistivity, tested according to the 85°C/85% biased humidity test. Besides, they are sulfur impervious and the AEC-Q200 qualification makes these product series an appropriate choice for important high reliability applications. The TNPW is suitable for precision down to 0.1% 10ppm, offered with 0402 to 1210 sizes. The TNPU is an extension for tighter precision, down to 0.02% 5ppm, with three package sizes, 0603, 0805 and 1206. The TNPW series is offered with pure tin termination plating which is RoHS compliant, but the series is also offered with tin-lead termination.
