t-1 3 / 4 (5 mm), t-1 (3 mm), 5 volt, 12 volt, integrated resistor led lamps technical data features ? integral current limiting resistor ? ttl compatible requires no external current limiter with 5 volt/12 volt supply ? cost effective saves space and resistor cost ? wide viewing angle ? available in all colors red, high efficiency red, yellow, and high performance green in t-1 and t-1 3 / 4 packages description the 5 volt and 12 volt series lamps contain an integral current limiting resistor in series with the led. this allows the lamp to be driven from a 5 volt/12 volt source without an external current limiter. the red leds are made from gaasp on a gaas substrate. the high efficiency red and yellow devices use gaasp on a gap substrate. the green devices use gap on a gap substrate. the diffused lamps provide a wide off-axis viewing angle. the t-1 3 / 4 lamps are provided with sturdy leads suitable for wire wrap applications. the t-1 3 / 4 lamps may be front panel mounted by using the hlmp-0103 clip and ring. figure a. t-1 package. figure b. t-1 3 / 4 package. package dimensions HLMP-1600, hlmp-1601 hlmp-1620, hlmp-1621 hlmp-1640, hlmp-1641 hlmp-3600, hlmp-3601 hlmp-3650, hlmp-3651 hlmp-3680, hlmp-3681
