Image of Vishay TNPW Series Thin-Film Chip Resistors - Construction

The TNPW thin film chip resistor construction offers significant advantages compared to other resistor types. The resistive element is a high-quality homogeneous material with meandering laser trimming of the resistive element, shown here. This meander laser trimming allows the resistor to evenly distribute thermal energy across the entire resistive element when the resistor is in use. Evenly distributing power dissipation and thermal energy across the resistive element enhances the stability of TNPW components by reducing the intensity of any single hot spot on the resistive film.
