Vishay has announced 0805 SMD resistors that combine 450V operation with ±0.1% tolerance and a temperature coefficient as low as ±10ppm/K.

They are the TNPV0805 e3 series, introduced as part of the greater TNPV e3 series (table below) of automotive high-voltage thin-film flat chip resistors.

"Typical applications for the AEC-Q200 qualified device will include voltage measurement in automotive and industrial inverters, voltage dividers for battery management systems, on-board chargers, and test and measurement equipment," according to the company.

Resistance options span 180k to 1MΩ and options include lower precision (±1 or ±0.5 %) and wider thermal coefficient (±50, ±25 or ±15ppm/K) parts.

Operation is over -55 °C to +155 °C, and load-life stability can be as good as ≤0.05 % for 1,000 hours at rated power and +70°C ambient temperature. Sulphur resistance is in accordance with ASTM B 809.

They are halogen-free, RoHS-compliant and pure matte tin plated – compatible with Pb-free and Pb-inclusive soldering.
