polyswitch resettable devices C telecommunications & networking devices 233 rohs compliant, elv compliant 12 resistance-sorted and resistance-matched devices resistance-sorted devices (part number suffix rx, where x = 1, 2, a, b, c, f etc.) are supplied with resistance values that are within specified segments of the devices full range of resistance. feature ? narrow resistance range. benefits ? greater flexibility for design engineers. ? lower resistance devices can allow for increased loop length on line card designs. ? higher resistance devices may provide greater protection by offering faster time-to-trip. resistance-sorted devices most tcf, trf and ts devices are available in resistance-sorted and/or resistance-matched versions. resistance-matched devices are supplied such that all parts in one particular package (or reel) are within 0.5 ? of each other (1.0 ? for trf250-080t devices). individual matched packages are supplied from the full resistance range of the specified device. feature ? tighter resistance balance between any two parts in a package. benefits ? resistance-matched devices may reduce the tip-ring resistance differential, reducing the possibility of line imbalance. resistance-matched devices part numbering system for radial-leaded telecommunications and networking devices trf*250 -120 t -ra -b-0.5 -2 p ackaging 2 = tape and reel 0.130 = special lead length in inches (blank) = bulk b-x.x = resistance mat che d in bins of x.x ?
