New series of high voltage thin film flat chip resistors – the industry ’s first combination of precision features (low VCR <1ppm / V, tight tolerances to ± 0.1% and low TCR to ± 10ppm / K – high resistance Vishay has set the operating voltage Raised to 1000V).
The new TNPV e3 series devices have typical thin-film chip resistors with similar case sizes, which can only provide a voltage of 200V, thereby reducing the number of components and saving the circuit by replacing larger resistors and multiple devices of similar case sizes Board space and reduces the cost of precision high-voltage circuits. Special high-voltage thick-film resistors can also be replaced, because of their superior voltage coefficient and unmatched accuracy at high voltages, they can significantly improve performance.
Vishay's TNPV e3 series is available in 1206 and 1210 sizes. It can operate within a resistance range of 121kohm to 3.01Mohm, can operate within a temperature range of -55C to + 125C, and has a rated power consumption of 0.33W at an ambient temperature of 70C. . These resistors are very stable and reliable under various environmental conditions, which has been proven, and their excellent load life stability can be ≤ ± 0.05% within 1,000 hours at rated power and + 70C, at 85 ° C and 85 % Relative Humidity can have excellent moisture resistance at 1,000 ° C for hours and sulfur resistance according to ASTM B 809.
These specifications enable designers to use RoHS-compatible and halogen-free devices in most areas of modern electronics, where accuracy, reliability, and stability at high operating voltages are the primary issues. Accurate voltage measurement is essential for various industrial and automotive high-voltage applications, including power and frequency inverters for photovoltaics, wind energy, electric vehicles (EV) and hybrid electric vehicles (HEV); electric vehicles and hybrid vehicles Battery management system; lighting; the company said it also has test and measurement equipment.
