Automotive Grade Products Offer Increased Accuracy With TCR Down to ± 2 ppm/K and Tight Tolerances Down to ± 0.02%

MALVERN, Pa. — May 27, 2020 — Vishay Intertechnology, Inc. today announced that the company has extended its TNPU e3 series of Automotive Grade ultra precision thin film flat chip resistors with lower temperature coefficients down to ± 2 ppm/K in the 0603, 0805, and 1206 case sizes.

Offering excellent long term stability — for example, permitted maximum resistance change ≤ 0.05 % for 1,000 hours at rated power P70 — the Vishay Draloric TNPU e3 series combines the proven reliability of the well-known TNPW e3 series with lower TCR and tighter tolerances down to ± 0.02 % for increased accuracy. This unique combination makes the AEC‑Q200 qualified resistors perfectly suited for applications such as operational amplifier circuits and sensors for test and measurement, automotive, industrial, medical, and telecommunications equipment.

The TNPU e3 series with TCR down ± 2 ppm/K is available in 0603, 0805, and 1206 case sizes, with resistance values from 500 Ω to 20 kΩ. 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 +125 °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 using wave, reflow, or vapor phase. The resistors are RoHS-compliant, and their pure tin plating provides compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
