Note: Use for repetitive pulses where the average power dissipation is
not to exceed the component rating at 70°C. Surge handling capacity
for low-repetitive surges may be significantly greater than shown above.

IRC Type
(CHP 1/8, CHP 1/2, CHP 1, or CHP 2)
Temperature Coefficient
(50 ppm, 100 ppm)
Resistance Value
(100 ohms and greater - First 3 significant digits plus 4th digit multiplier)
Example: 100 ohms = 1000, 1000 ohms = 1001, 150,000 ohms = 1503
(Less than 100 ohms - "R" is used to designate decimal)
Example: 51 ohms = 51R0, 1 ohm = 1R00, 0.25 ohms = R250
Tolerance
(C = 0.25%, D = 0.5%, F = 1.0%; G = 2.0%; J = 5.0%)
