MRC Series

Metal Glaze

Surface Mount Power Resistor

MRC Series Issue April 2010 Sheet 2 of 2

Sample Part No.

IRC Type

(MRC 1/2)

Temperature Coefficient

50 ppm, 100 ppm, 200 ppm

Resistance Value

(100Ω and greater - First 3 significant figures plus 4th digit multiplier)

Example: 100Ω = 1000, 1000Ω = 1001, 150,000Ω = 1503

(Less than 100Ω - "R" is used to designate decimal)

Example: 51Ω = 51R0, 1Ω = 1R00, 0.25Ω = R250

Tolerance

(C = 0.25%, D = 0.5%, F = 1.0%, G = 2.0%, J = 5.0%)

Packaging Code*

(BLK = Bulk, 7 = 7" Reel, 13 = 13" Reel)

RoHS Compliance

LF = RoHS compliant version

Note: Use for repetitive pulses where the average power dissipation

is not to exceed the component rating at 70°C. Surge handling capacity

for low-repetitive surges may be significantly greater than shown above.
