TE Connectivity is a leading supplier of standard and custom-designed power
resistors for industrial, control and general- purpose applications.
The TE range of flameproof coated tubular ceramic core resistors use both
standard and edge wound (corrugated) winding methods to improve power
handling capability. Designed for heavy duty machinery, electrical equipment,
motor control etc. requiring stability and reliability.

Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or
an approximate sine-wave root-mean-square (RMS) alternating-current (AC)
continuous working voltage at commercial line frequency and waveform
corresponding to the power rating, as determined from the following
formula:
RCWV = √P x R
Where : RCWV = Rated DC or RMS AC continuous working voltage at
commercial-line frequency and waveform (volt)
P = Power Rating (watt)
R = Nominal Resistance (ohm)
