Notes

• For additional information on packaging, refer to the Through-Hole Resistor Packaging document (www.vishay.com/doc?31544).

(1) Tolerances of ± 0.5 % (D), ± 0.25 % (C) and ± 0.1 % (B) are available only in 50 ppm and 25 ppm temperature coefficients.

Notes

(2) Lead length for product in bulk pack. For product supplied in tape and reel, the actual lead length would be based on the body size, tape

spacing and lead trim.

(3) Available with 0.032" (0.813 mm) lead [CMF60..95]

(4) 0.260" ± 0.020" (6.60 mm ± 0.51 mm) for values > 5 M
