TE Connectivity (TE) is a leading supplier of standard and custom-designed power
resistors for industrial, control and general-purpose applications. The CJT Series of
resistors are advantageous to conventional ceramic resistors in the terms of weather
proofing, oscillation-resistance and safety. They are widely applied to a range of electrical
circuits including power supplies, inverters and servo systems. With easy airtight fitting
and the ability to fit a heatsink the resistor is highly suited to challenging environmental
conditions.
