High Voltage Resistors and Dividers
FEATURES
• 30,000 volts capability.
• Very low voltage coefficient to less than 0.1ppm/Volt.
• Outstanding stability under adverse conditions.
• Stable cermet resistive element bonded to a high-purity
alumina substrate.
• Tough epoxy-based coating and high voltage stability.
• Designs built from customer supplied schematics.
• Dividers available leaded or non-leaded.
• Typical resistance ratios of 1000:1, 2000:1, etc.
• TCR tracking to ± 5ppm/°C depending on values.
