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.

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
