20 = 20 W

Resistance Value

<100 ohms ... “R” represents decimal

point (examples: 7R50 =

7.5 Ω; R500 = 0.5 Ω)

≥

100 ohms.... First three digits are

significant, fourth digit

represents number of

zeros to follow (exam-

E = Tape & Reel

Blank = Tubes

How to Order

Power dissipation is 2.8 W at an ambient temperature of 25 ˚C when mounted on a

double-sided copper board using FR4 standard, 70 µm of copper, 39 x 30 x 1.6 mm.
