The Perspective:
With typical thin film chip resistors in comparable case sizes only offering voltages to 200 V, Vishay Draloric TNPV e3 series devices reduce component counts to save board space and lower costs in precision high-voltage circuits by replacing larger resistors and multiple devices in similar case sizes. Special high-voltage thick film resistors can also be replaced, which allows for significantly enhanced performance due to superior voltage coefficient and unrivaled precision properties at high voltages. With their excellent load-life stability, superior moisture resistivity, and sulfur resistivity, the resistors provide high stability in various environmental conditions. This allows designers to use the devices for most fields of modern electronics where precision, reliability, and stability at high operating voltages are primary concerns, including various high-voltage industrial, automotive, and lighting applications.
Availability: Samples and production quantities of the TNPV e3 series resistors are available now, with typical lead times of eight to ten weeks for larger orders.
