This comprehensive questionnaire is designed to gather essential specifications for high voltage and power resistors. It includes critical parameters such as ohmic value, tolerance, maximum dimensions, operating voltage, and continuous load details. Additionally, it addresses pulse characteristics, cooling mediums, temperature requirements, and special coating requests. Users will also need to provide information about the current vendor and part number. This data is crucial for ensuring optimal design and functionality in high-power applications.
