(international electrotechnical commission). the sensitivity of pa will increase 20 db compared to the ubar indication. example: -60 db (0 db = 1 v/ubar) = -40 db ( 1v/pa) 2. all specifcations measured at 5~35c, humidity at 45~85%, under 86~106 kpa pressure, unless otherwise noted. solderability parameter conditions/description min typ max units hand soldering for 2 0.5 seconds 270 280 290 c date page
