Vishay Extends High Stability Thin Film Flat Chip Resistors

Automotive Grade Devices Save Space and Increase Efficiency With TCR of ± 25 ppm/K and Tight Tolerances of ± 0.1 %

Vishay Intertechnology, Inc. announced that the company has extended its TNPW e3 series of Automotive Grade high stability thin film flat chip resistors with a new device in the compact 0201 case size. Offering low TCR of ± 25 ppm/K with tight tolerances down to ± 0.1 %, the resistor is designed to increase accuracy in automotive, industrial, test and measurement, and medical equipment, in addition to mobile devices and wearables.

Offering excellent long term stability — for example, permitted maximum resistance change of ≤ 0.05 % for 1,000 hours at rated power P₇₀ — in a small size, the AEC-Q200 qualified device released today is ideal for space-constrained applications such as automotive and industrial sensors and electronic modules, smartphones and tablets, smartwatches and fitness trackers.

The complete TNPW e3 series is available in 0201, 0402, 0603, 0805, 1206, and 1210 case sizes, with resistance values from 10 Ω to 3.01 MΩ. Offering superior moisture resistivity (85 °C; 85 % RH), sulfur resistance in accordance to ASTM B 809, and a wide temperature range of -55 °C to +155 °C, the resistors’ extremely stable operation withstands even harsh environmental conditions.

The devices are suitable for processing on automatic SMD assembly systems and for automatic soldering. The resistors are halogen-free and RoHS-compliant, and their pure tin plating provides compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
