Resistance Value Code

<100 Ω: “R” represents decimal point

(example: R050 = 0.05 Ω, 5R00 = 5.00 Ω,

92R0 = 92 Ω)

≥100 Ω: First three digits are significant,

fourth digit represents number of zeros to follow

(example: 2000 = 200 Ω, 3002 = 30 KΩ)

Resistance Tolerance

F = ±1 %

G = ±2 %

J = ±5 %

TCR (PPM/°C)

W = ±600

T = ±300

X = ±100

Z = ±50 (For ≥0.1 Ω resistance, available upon request)
