* Custom configurations are available upon request The UHVC ultra-high voltage chip resistor series from Exxelia Ohmcraft® offers the highest voltage ratings of up to 20kV available in a SMD resistor. By utilising their patented Micropen® precision printing technology, they are able to provide a superior ultra-high stability (tolerances down to ±1% and TCR as low as ±100 ppm/°C) and very low noise. The UHVC series offers a resistance range up to 10GΩ for trimmed resistors or up to 50GΩ for untrimmed resistors.Exxelia Ohmcraft’s UHVC ultra-high voltage surface mount resistor series are ideal for replacing through hole resistors due to their high voltage rating capabilities, allowing savings on assembly and board space costs. They could also be used to replace resistor arrays with a single-chip resistor.Due to the high voltage ratings of the UHVC series, these resistors must be potted upon assembly.Due to numerous possible options for the UHVC resistor series, each request will be individually reviewed. Please include the following information for any requirement:

• Resistance value
• Required SMD package size
• Tolerance (%)
• TCR value (ppm/°C)
• Voltage rating
• Termination
