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.
APPLICATIONS
Applications include power supplies, transformers and any
application requiring operation within an environment where
high voltages are used.
