The entire set has a TC of 5ppm/°C! A resistor set that strictly matches USG resistors, reducing thermal drift and aging effects in high voltage measurements.
【Selected Resistance Set for Achieving Ultra-High Precision High Voltage Measurement】 The 'Type USGS' from Cadock, USA, is a high-voltage resistance set that connects multiple high-precision USG1110 resistors in series, achieving an astonishing temperature stability of TC 5 ppm/°C for the entire set. 【Main Features】 - Extremely low set TC: Individual characteristic evaluation and selection using a fully automated data acquisition system, guaranteeing a set TC of 5 ppm/°C or less for the entire set. - Maximum operating voltage of 50kV: Standard sets available for 30kVDC (3-resistor configuration, 300MΩ) and 50kVDC (5-resistor configuration, 500MΩ). - Extremely low voltage coefficient: Minimizes resistance changes (VC) due to voltage fluctuations, maintaining high precision across a wide range of applied voltages. - Applications: High-voltage generation equipment, standard calibrators, and precision physical property analysis devices that require the highest level of accuracy. 【Main Specifications】 - Maximum operating voltage: 30kVDC (USGS-3) / 50kVDC (USGS-5) - Total resistance value of the set: 300MΩ / 500MΩ - Set tolerance: ±0.10% - Set temperature coefficient: 5 ppm/°C (+10℃ to +50℃) - Voltage coefficient: 0.02 to 0.03 ppm/V

Company information
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.
