Resistance Value Code

<100 Ω: “R” represents decimal point

(example: R005 = 0.005 Ω, 5R00 = 5.00 Ω)

≥100 Ω: First three digits are significant,

fourth digit represents number of zeros to follow

(example: 1000 = 100 Ω, 5001 = 5000 Ω)

Packaging

B = bulk

Pin Configuration (see Pin Configuration diagrams)

(blank) = standard configuration

1 = 1-3 configuration

2 = 2-4 configuration

These resistors must be attached to a suitable heat sink. The maximum

internal resistor temperature is +175 °C.
