Extended series of high voltage thin film flat chip resistors in compact size

Vishay Intertechnology Inc. has extended its TNPV e3 series of Automotive Grade high voltage thin film flat chip resistors with a smaller 0805 case size. The Vishay Draloric TNPV0805 e3 is claimed to be the industry's first device in the compact 0805 case size to combine high operating voltages to 450V with tight tolerance of ± 0.1% and low TCR down to ± 10ppm/K.

The device reduces component counts to save board space with its small size and high voltage capability. It lowers costs by replacing larger resistors and multiple devices in similar case sizes with no compromising on precision. Typical applications for the AEC-Q200 qualified device will comprise voltage measurement in automotive and industrial inverters, onboard chargers, voltage dividers for battery management systems, and test and measurement equipment.

The complete series is offered in 0805, 1206, and 1210 case sizes, with resistance values from 121kOhm to 3.01MOhm, an operating temperature range of -55C to +155C, and maximum operating voltage up to 1,000V for the largest case size. The resistors are highly stable and reliable in various environmental conditions, with excellent load-life stability of ≤0.05% for 1,000 hours at rated power and +70C ambient temperature, superior moisture resistivity (85C, 85% RH), and sulfur resistance in accordance with ASTM B 809.

The devices are ideal for processing on automatic SMD assembly systems and automatic soldering. The resistors are halogen-free and RoHS-compliant, and their pure matte tin plating offers compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
