Vishay has extended its TNPU e3 series of automotive grade ultra-precision thin film flat chip resistors with a new space-saving component in the compact 0402 case size.
Offering high long-term stability – for example, permitted maximum resistance change ≤0,05% for 1000 hours at rated power P70 – the Vishay Draloric TNPU e3 series combines the proven reliability of the well-known TNPW series with lower temperature coefficients down to ±5 ppm/K and tighter tolerances down to ±0,02% for increased accuracy. This combination makes the AEC-Q200 qualified resistors ideally suited for applications such as operational amplifier circuits and sensors for test and measurement, automotive, industrial, medical and telecommunications equipment.
With the addition of the 0402 case size, the Vishay Draloric TNPU e3 series is now available in 0402, 0603, 0805 and 1206 case sizes, with resistance values from 100 Ω to 511 kΩ. Offering superior moisture resistivity (85°C; 85% RH), sulphur resistance in accordance to ASTM B 809 and a wide temperature range of -55°C to +125°C, the resistors’ highly stable operation withstands even harsh environmental conditions.
TNPU e3 series components are suitable for processing on automatic SMD assembly systems and for automatic soldering using wave, reflow, or vapour phase. The resistors are RoHS-compliant and their pure tin plating provides compatibility with lead-free and lead-containing soldering processes.
