Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shaped, and then baked. Resistance decreases as temperature increases. Resistance is more prone to drifting than with other types. Standard 'classic' resistor. Sold in multiples of 5.

Values 100K and lower are 5% tolerance, values 100K and higher are 10% tolerance.

  • 1/2 watt
  • -55° C to 125° C operating range
  • 350 V working, 700 V overload
  • Low inductance
  • Low capacitance
  • Better pulse endurance characteristics than film type resistors
  • EIA color coded
RoHS Compliant

These resistors are easily within spec. They may be slightly lighter in color to the old 60's resistors I was trying to match. Of course, it's also possible my old resistors are simply cooked, darkened over time from smokey clubs, and who knows what else. These fit nicely into my circuit board and accepted the solder with the molecular efficiency that you would expect. The color bands were clearly marked and easy to read for someone that needs #250 readers. I like these resistors. Reasonably priced too!
