± 100 ppm/°C, ± 50 ppm/°C available;
Available
non-inductive only available with TC of
± 200 ppm/°C
• Tolerance: ± 1 %; ± 2 %; ± 5 %; ± 10 %
• High voltage (up to 45 kV)
Available
• For oil bath or open air operation
• Standard ROX product is coated; optional uncoated
version of the ROX product is available on request
• Matched sets available
• Special testing available upon request
• Applications: HV power supplies; laboratory equipment;
power control; aeronautical
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Note
* This datasheet provides information about parts that are RoHS-compliant and / or parts that are non RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details
