High precision voltage divider Caddock USVD2-B10M-010-02 ideal for analytical measurement and medical equipment
Caddock Electronics Ultra-Precision Voltage Dividers
Product Overview
Caddock Electronics offers Type USVD and Type HVD Ultra-Precision Voltage Dividers, designed for applications requiring the highest precision in voltage division. The USVD series covers a range of 450 Volts DC up to 2000 Volts DC, while the HVD series extends from 1500 volts DC to 5000 volts DC. These dividers are constructed from selected high-performance resistors (USVD) or monolithic ceramic sandwich construction (HVD), ensuring outstanding voltage division performance. They are ideal for demanding applications in medical equipment, laboratory equipment, and analytical instruments, offering tight ratio tolerances and low temperature coefficients.
