Compared to TC 2ppm/°C, the allowable tolerance is 0.01%! Pressure divider 'USVD'
Unmatched precision at 450V to 2,000VDC! The combination of USF300 resistors achieves outstanding temperature stability and low load drift.
**Ultra-Precision High-Voltage Divider that Maximizes the Limit Accuracy of DC Voltage Measurement Instruments** The 'Type USVD' from Cadock, USA, is an ultra-precision divider that offers industry-leading accuracy in the range of 450VDC to 2,000VDC. **Main Features** - **Top-Level Divider Accuracy**: Boasting a maximum ratio tolerance of 0.01% and a ratio temperature coefficient of 2 ppm/°C, it eliminates deviations in the division ratio caused by environmental changes and current flow to the utmost extent. - **Carefully Selected Element Structure**: By optimally pairing and coupling ultra-precision resistors from the 'USF300 series', it ensures outstanding matching performance. - **Long-Term Stability**: The aging change (shelf ratio stability) is exceptionally low, at less than 10-20 ppm/year in the first year. - **Applications**: Ultra-high-precision digital multimeters, standard calibration devices, medical precision measuring instruments, and research and development measurement equipment. **Main Specifications** - **Maximum Operating Voltage**: 450V / 650V / 1,400V / 2,000VDC - **Total Resistance Values**: 1MΩ / 2MΩ / 10MΩ / 20MΩ - **Division Ratios**: 100:1 / 1,000:1 - **Ratio Tolerance**: 0.01% / 0.025% - **Ratio Temperature Coefficient**: 2 ppm/°C (-40℃ to +85℃)

Our company was established in September 1975 as the import sales agent for BECKMAN (now BI Technology Japan Co., Ltd.), RCL-ELECTRONICS (now IRC), and CADDOCK ELECTRONICS. Since then, we have expanded our offerings to include LED products, rectifiers, relays, memory ICs from GENERAL INSTRUMENT (now VISHAY), various switches from ITW, and currently engage in the import and sales of a wide range of electronic components. Additionally, since 1977, we have also been importing mechanisms, ICs, and other electronic components for small cassettes.
