PART NUMBERING MECHANICAL S2208CA 150 J H B TCR E: 25 ppm H: 50 ppm K: 100 ppm TOLERANCES B: 0.1% C: 0.25% D: 0.5% F: 1% G: 2% J: 5% K: 10% M: 20% RESISTANCE VALUE Three or four digits are used with all leading digits significant. Four digits are used for 1% tolerance or lower, otherwise three digits are used. The last digit specifies the number of zeros to add. The letter "R" is used to represent the decimal for fractional ohmic values. Example: 5R6 is 5.6 ohms. Length Width Thickness Top Term. Bottom Term.
