Type USVD Ultra-Precision Voltage Dividers have the very highest precision available in voltage dividers in the range of 450 Volts DC up to 2000 Volts DC. These dividers are formed by bonding together two selected Type USF Ultra-Precision Resistors. The precise selection of these high performance resistors, which form the voltage dividers, makes possible the outstanding voltage division performance. Ratio Tolerance as tight as 0.01% and Ratio TC of 2ppm/C.
The USVD and HVD series are ultra‑precision voltage dividers designed for high‑performance applications such as medical, laboratory and analytical equipment. USVD models cover 450 V to 2 kV DC, while HVD models extend the range to 5 kV DC, both offering tight ratio tolerances and low temperature coefficients.
Key specifications include absolute tolerance of ±0.10%, ratio tolerance of 0.01% (USVD) or 0.05% (HVD), absolute temperature coefficient of 10 ppm/°C (USVD) or 30 ppm/°C (HVD), and operating temperature from –40 °C to +85 °C. Custom ratios are available for high‑volume orders.
