6 mechanical these displays are hermetically sealed for use in environments that require a high reliability device. these displays are designed and tested to meet a helium leak rate of 5x10 -8 cc/sec. these displays may be mounted by soldering directly to a printed circuit board or insertion into a socket. the lead-to-lead pin spacing is 2.54 mm (0.100 inch) and the lead row spacing is 15.24 mm (0.600 inch). these displays may be end stacked with 2.54 mm (0.100 inch) spacing between outside pins of adjacent displays. sockets such as augat 324-ag2d (3 digits) or augat 508-ag8d (one digit, right angle mounting) may be used. the primary thermal path for power dissipation is through the device leads. therefore, to insure reliable operation up to an ambient temperature of +100 c, it is important to maintain a base-to-ambient thermal resistance of less than 35 c watt/device as measured on top of display pin 3. for further information on soldering and post solder cleaning, see application note 1027, soldering led components . preconditioning these displays are 100% pre- conditioned by 24 hour storage at 125 c, at 100 c for the hdsp-098x series. contrast enhancement these display devices are designed to provide an optimum on/off contrast when placed behind an appropriate contrast enhancement filter. for further information on contrast enhancement, see application note 1015, contrast enhancement for led displays. over range display the over range devices display 1 and decimal point. the character height and package configuration are the same as the numeric and hexadecimal devices. character selection is obtained via external switching transistors and current limiting resistors. absolute maximum ratings description symbol min max unit storage temperature, ambient t s ?5 +125 c operating temperature, ambient t a ?5 +100 c forward current, each led i f 10 ma reverse voltage, each led v r 5v
