CR-PF Series Ultra-Low Lead Content Thick Film Resistor
Typical Part Marking
±5 % (E24):
CR0603-PF, CR0805-PF, CR1206-PF
Resistance value is expressed by 3 digits. The first two digits represent the significant figures of the nominal
resistance value in ohms; the third digit represents the exponent for a base of 10.
Example:
102
= 10 x 102 = 1000 ohms = 1K ohms
Note: “R” represents the decimal point for CR1206-PF.
102
±1 % (E96):
01A
CR0603-PF
In cases where the marking space is too small to accommodate 4 digits, the marking shall consist of 2 digits
followed by an alpha character multiplier.
Example:
01A
= 100 x 100 = 100 ohms
