Ordering Data Sample Part No. IRC Type (MMA0204, MMB0207, MMC0310) MMA0204 50 2203 F 13 Temperature Coefficient 50 = 50 ppm/C; 100 = 100 ppm/C 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%) Packaging Details (BLK = Bulk, 7 = 7" Reel, 13 = 13" Reel) Wire and Film Technologies Division * 4222 South Staples Street * Corpus Christi Texas 78411 USA Telephone: 361 992 7900 * Facsimile: 361 992 3377 * Website: www.irctt.com MM Series Issue March 2009 Sheet 3 of 3 |
