has developed a 1W carbon composition resistor
to accompany its existing W and W carbon composition resistor
Carbon composition resistors
, now being phased out, use a mixture of finely-ground carbon and a ceramic insulating material.
is proud to announce a new technologically-advanced RM, (carbon-ceramic) and RO, (carbon-polymer) series of carbon composite resistors that can replace 1 watt and 2 watt carbon composition resistors
, which are difficult to source.
Due to its power film resistive element and laser spiral calibration, these resistors present alternatives carbon composition resistors
and replacements for wirewounds up to 5 W.
Although film and composition resistors
are available up to 3W, they can present problems in performance, precision, TCR stability and environmental reliability when operated at that power level.
