Note:
RoHS compliance is noted by inserting “LF”
into the part number immediately following the
tolerance designator. RoHS compliant metallization is 96.5% Sn / 3% Ag / 0.5% Cu. RoHScompliant product is NOT backwards compatible to Sn/Pb soldering environments.
Resistance Value
(100 ohms and greater - First 3 significant figures plus 4th digit multiplier)
Example: 100 ohms = 1000, 1000 ohms = 1001, 150,000 ohms = 1503
(Less than 100 ohms - ‘R’ is used to designate decimal)
Example: 51 ohms = 51R0, 1 ohm = 1R00, 0.25 ohm = R250
Tolerance
(D = 0.5%, F = 1.0%)
