Marking: From 0805 to 2512: Resistance value is expressed by 4 digits, the first "R" means decimal point and the other digits represent for the normal resistance in . eg., 15m= R015, 100m= R100, For 0603: The marking of CRM06 can not represent by 4 digits but by 3 digits. (a) Resistance value higher than or equals to 100m is represented by E96 series. However, for resistance value not in the list of E96, 3 digitals with underline in E24 series is used. eg., 100m= 01Z, 200m= 08Z, 120m= 012 (b) Resistance value lower than 100m is represented by 2 digits plus a symbol L. eg., 10m= 10L, 20m= 20L, 47m= 47L For 0402 and 0201: No Marking.
