MM FAMILY STANDARD SIZES, SOLDER PADS AND PACKAGING:
DIMENSIONS (mm and (inches)):
*C dimension is average termination width.
RECOMMENDED SOLDER PAD DIMENSIONS (REFLOW):
To ensure excellent solderability performance, IRC recommends the following pad design. This design will provide a large repeatable
solder fillet to the MM resistor on reflow processes and will provide maximum heat transfer to the PC board in high power applications.
By placing the MM on the solder paste while the paste is in the "tacky" state, the MM will be held in position until solder reflow begins.
The pad design then uses the surface tension of the molten solder to pull the component to the center of the solder pad. The
placement of a via rising above the board level directly beneath the MM is not recommended.
STANDARD REEL PACKAGING PER EIA-481:
* The 13" reel is considered standard and will be supplied unless otherwise specified.

IRC Type
(MMA0204, MMB0207, MMC0310)
Temperature Coefficient
(50 or 100)
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
(F = 1.0%)
