Type CJT Series
Tyco Electronics 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
weatherproofing, oscillation-resist-
ance 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.
