STANDARD ELECTRICAL SPECIFICATIONS
GLOBAL MODEL (1) HISTORICAL MODEL (1) POWER RATING P W 25 °C RESISTANCE RANGE Ω TOLERANCE ± % WEIGHT (typical) g
CA0001 CA-1 1.0 0.1 to 1K 5, 10 0.65
CA0002 CA-2 2.0 0.1 to 2.4K 5, 10 0.80
CA4000 CA-4xxx 2.0 to 8.8 0.1 to 1.02K 5, 10 See below
CA5000 CA-5xxx 2.5 to 11.0 0.1 to 7K 5, 10 See below

Note (1) CA4000 and CA5000 model numbers are calculated from the CA4000 power rating of 4 W per inch and CA5000 power rating of 5 W per inch. The last three digits of the model number are the body length of the resistor in inches (decimal is between the first and second digit). Example: CA5150 = 1.50 inches x 5 W per inch = 7.5 W.

Note

  • Wirewound CA resistors can reliably function as a fuse and as a resistor. Such components involve compromise between fusing and resistive functions; therefore, each design should be tailored to the application to ensure optimum performance.
