Precision / Ultra-Precision Resistors

At Rhopoint Components we have a wide selection of high precision and ultra-precision resistors in an array of styles, packages, and covering virtually any resistance values from 0.002Ω to 500MΩ in both surface-mount (SMD) and through-hole (THT) options. From traditional wire-wound resistors handmade to the highest standard to new technology chip resistors and innovative resistive materials, we can achieve very low tolerances from ±0.005% and TCRs from ±1ppm. Our technical team is always ready to discuss your project, however big or small, to find the right solution for your application, whatever your priorities.
