TT planar resistors are rated from 5 to 40kV
A TT Electronics Welwyn Components product story
Edited by the Electronicstalk editorial team Sep 17, 2009
TT Electronics Welwyn Components has extended its portfolio of precision resistors with a range of high-voltage planar resistors rated from 5 to 40kV in air.
Offering nominal values from 1K0 to 40G, the PHVP family is available in precision grades to +/-0.05 per cent, with temperature coefficients as low as 10ppm/C.
TT Electronics Welwyn Components has a range of high-voltage planar resistors rated from 5 to 40kV in air.
The non-inductive, non-magnetic design delivers voltage coefficients down to -0.05ppm/V.
Construction of the resistors ensures RoHS compliance as well as high accuracy.
Termination conductors and ruthenium-oxide resistive material are printed in a non-inductive pattern on a 96 per cent alumina substrate, while the resistors also feature screen-printed protection with tin-coated copper termination wires.
Availability in a choice of axial or radial configuration provides wide applicability including precision power supplies for electron microscopes, X-ray equipment, geophysical probes, semiconductor processing and particle accelerators.
The PHVP family is also suited to high-voltage industrial power supplies, for example in electrostatic spraying, powder coating, e-beam welding and insulation test equipment.
Where applications are not covered by the standard range, a custom design service is available.
Further options include surface-mount variants and gold-bondable pads.
The resistors are available immediately and Welwyn can also advise on competitor equivalent parts for which the PHVP series offers direct drop-in replacement alternatives.
