Tape and reel specifications. This package is available in 500-unit reels through designated sales channels with

the #TRMPBF suffix.

2.

The LT8440R is specified over the −55°C to 150°C junction temperature range. High junction temperatures degrade

operating lifetimes; operating lifetime is derated for junction temperatures greater than 150°C. Note that the

maximum ambient temperature consistent with these specifications is determined by specific operating

conditions in conjunction with board layout, the rated package thermal impedance and other environmental

factors.
