SCC Ultra R2 Green Rubber Mat - two layer P/N: RM(W"L")L2RGN Use Green Mats to Indicate Lead-Free Work Areas. Excellent resistance to solvents, hot solder, and soldering irons makes the Ultra-R2 mats the ultimate static safe work surface. Excellent electrical performance is assured by using a two-layer combination of static dissipative and conductive rubber materials. Ultra-R2 mats combine the low contact resistance and convenience of soft mats, with the conductivity and durability of hard laminates. Meets the requirements of ESD Standard 4.1, ESD Standard 20.20, EIA 625, MIL-HDBK-263, and MIL-STD-1686. Rtg: 106 ohms Rtt: 107 ohms Thickness: 0.060" Compatible with Constant Monitors.
