3644 Series, Round, 100-Ohm, Discrete, Twisted Pair Cable 3M 3644 Series cable is an excellent choice for digital communications applications requiring 100-Ohm impedance. It combines all the features that make for superior performance and easier handling in applications. The 3644 cable uses a dual shielding of aluminum/polyester film foil and tinned copper braid for excellent EMI/ESD protection. Its twisted pair configuration reduces crosstalk for balanced drive applications, resulting in higher quality communications. Its 28 AWG stranded, discrete color-coded wire is flexible and easy to use. The 3644 cable is an optimal cost/performance solution for LVDS digital 100-Ohm transmission applications where the cable length is less than four meters and transmission speeds are under 700 Mbytes per second. Applications include: Routers Switches Device-to-device digital communications Desktop monitors Factory automation equipment Medical equipment Kiosk displays and flat panel displays Solid Company, Superior Technology 3M promises innovative, quality products and service that make your life easier and better, from a company you can trust. 3M is a company of creative problem-solvers.
