High voltage thin film flat chip resistors are now in compact 0805 cases
Automotive-grade resistors in the TNPV e3 series of high voltage, thin film, flat chip resistors are now available from Vishay Intertechnology in a smaller, 0805 case size.
The Vishay Draloric TNPV0805 e3 is claimed to be the industry’s first such resistor available in the compact case size to combine high operating voltages to 450V with tight tolerance of ± 0.1 per cent and low TCR (temperature co-efficient resistance) down to ± 10 ppm/K.
The company said the small size with high voltage capability means the TNPV0805 e3 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. 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.
The complete TNPV e3 series is available in 0805, 1206, and 1210 case sizes, with resistance values from 121 kOhm to 3.01 MOhm, an operating temperature range of -55 to +155 degrees C and maximum operating voltage up to 1,000V for the largest case size. The resistors are stable in a variety of environmental conditions, with load-life stability of less than or equal to 0.05 per cent for 1,000 hours at rated power and +70 degrees C ambient temperature. They are also claimed to have superior moisture resistivity (85 degrees C, 85 per cent RH), and sulphur resistance in accordance with ASTM B 809.
The devices are suitable for processing on automatic surface mount assembly systems and for automatic soldering. The resistors are halogen-free and RoHS-compliant, and their pure matte tin plating provides compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
Samples and production quantities of the TNPV0805 e3 are available now, with typical lead times of 12 weeks.
