Note
The number of days for storage after the dry pack has been opened. Storage conditions are 25
°
C and 65%
RH max.
Cautions 1. Use of more than one soldering method should be avoided (except in the case of pin partial
heating method).
2. Because the
μ
PD78P054GC-8BT is under development, soldering conditions are not deter-
mined.
