RoHS compliance is noted by inserting “LF”

into the part number immediately following the

tolerance designator. RoHS compliant metalli-

zation is 96.5% Sn / 3% Ag / 0.5% Cu. RoHS-

compliant product is NOT backwards compat-

ible to Sn/Pb soldering environments.

IRC Type

(MMA0204, MMB0207, MMC0310)

Temperature Coefﬁcient

50 = 50 ppm/°Cꢁ 100 = 100 ppm/°C

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 = 0.5ꢀ, F = 1.0ꢀ)
