The TNPV series design offers significant advantages when compared to other resistor types. The resistive element is a high-quality homogeneous material with meander laser trimming. This trimming geometry allows the resistor to homogenously dissipate power and distribute thermal energy across the entire resistive element when the resistor is in use. This enhances the stability of TNPV components by reducing the intensity of any single hot spot on the resistive film. Additionally, the fine-trimming helps to reduce voltage gradients along the segments of the resistive element, thus enhancing stability at high voltages as compared to typical high voltage resistors with larger spacing between the current path segments. Another important aspect is reliability in Sulfur environments. An increase in incidents of corrosion failures related to high Sulfur-containing environments has been observed in the electronics industry, which has increased the interest in Sulfur-resistant resistors by designers. With Silver-Palladium inner termination and a special design that protects the integrity of the junction between the product termination and the top coating, the TNPV series is impervious to Sulfur exposure, as verified in accordance with the ASTM B 809 standard.
