Type USVD and Type HVD Ultra-Precision Voltage Dividers - 450 Volts to 5 KV Type USVD Ultra-Precision Voltage Dividers have the Type HVD Ultra-Precision Voltage Dividers are very highest precision available in voltage dividers in the range of 450 monolithic voltage dividers built with ceramic sandwich construction. Volts DC up to 2000 Volts DC. These dividers are formed by bonding These voltage dividers have ultra-precision performance in the together two selected Type USF Ultra-Precision Resistors. The precise range of 1500 volts DC to 5000 volts DC, with a Ratio Tolerance of selection of these high performance resistors, which form the voltage 0.05% and Ratio TC of 5ppm/°C. These dividers are ideal for high dividers, makes possible the outstanding voltage division performance. performance voltage division applications in medical equipment, Ratio Tolerance as tight as 0.01% and Ratio TC of 2ppm/°C. laboratory equipment, analytical instruments, etc. Part Number COoVpn(VoVetlirDmtnaaCuatgio)xneugs (DVRioTvl it:sa iRgo2en) R1 ResiRst2ancReT = R1 + R2 T(oRRlTea r:ta iRno2c)e R(RatTio : TR.2C).
