Vishay Intertechnology, Inc has extended its TNPV e3 series of Automotive Grade high voltage thin film flat chip resistors with a new TNPV0805 e3 resistor that is available in the compact 0805 case size to combine high operating voltages to 450 V with a tight tolerance of ± 0.1 % and low TCR down to ± 10 ppm/K. Typical applications for the AEC-Q200 qualified device will include voltage measurement in automotive and industrial inverters; voltage dividers for battery management systems; onboard chargers; and test and measurement equipment.
With its small size and high voltage capability, the TNPV0805 e3 resistor reduces component counts to save board space and lowers costs by replacing larger resistors and multiple devices in similar case sizes, without compromising on precision. The complete TNPV e3 series is available in 0805, 1206, and 1210 case sizes, with resistance values from 121 kΩ to 3.01 MΩ, an operating temperature range of -55 °C to +155 °C, and maximum operating voltage up to 1,000 V for the largest case size.
These resistors are stable and reliable in a variety of environmental conditions, with excellent load-life stability of ≤ 0.05 % for 1,000 hours at rated power and +70 °C ambient temperature; superior moisture resistivity (85 °C; 85 % RH); and sulfur resistance in accordance with ASTM B 809.
Key Features
- High operating voltage Umax. up to 1000 V
- Low voltage coefficient < 1 ppm/V
- Excellent overall stability at different environmental conditions ≤ 0.05 % (1000 h rated power at 70 °C)
In addition, these devices are suitable for processing on automatic SMD assembly systems and for automatic soldering. Samples and production quantities of this device are available now with typical lead times of 12 weeks.
