Type CJT Series
TE Connectivity supplies 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 weatherproofing,
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.
