The last digit specifies the number of zeros. For values <100 ohms, R is used to designate the decimal position. Multiple values are separated by a slash (/). e.g: 1001 = 1K 75R0 = 75 1001/1002 = 1K/10K 1 = 100 5 = 500 A = 1000 For Lead Free Products (100% Sn Terminal Finish): Form Factor S4 Note 1: Note 2: Note 3: Note 4: Absolute Resistance Tolerance T = 0.01% Q = 0.02% A = 0.05% B = 0.10% C = 0.25% D = 0.50% F = 1.00% Resistance Ratio Tolerance Q = 0.02% A = 0.05% B = 0.10% C = 0.25% D = 0.50% Z = NONE Resistance Value XXXX / XXXX R1 Value R2 Value The first 3 digits are significant figures.
