Product Description
The HVHR series of high-voltage, high-resistance precision resistors are manufactured using thick film technology with independently developed electronic paste and an alumina ceramic rod as the carrier. These resistors are designed to solve customer design and manufacturing challenges in the global electronic industry. They offer a wide resistance range from 2G to 21G, high initial accuracy up to 1.1%, and a low temperature coefficient of 100ppm/ within the -25 to +95 range. The resistors undergo 100% high-voltage testing before leaving the factory to ensure performance under high-voltage conditions. Key materials and processes are independently controlled, ensuring stable quality and timely delivery. These resistors are ideal for applications requiring high precision, high voltage, low voltage coefficient, and high reliability.
