Low NoiseMinmax's MSDW1000 2W DC/DC's are in "gull-wing" SMT package and
meet 245]/10sec in solder-reflow for lead free process.
The series consists of 28 models that operate over input voltage ranges of
4.5-9VDC, 9-18VDC, 18-36VDC and 36-75VDC which provide precisely
regulated output voltages of 3.3V, 5V, 12V, 15V, {5V, {12V and {15VDC.
The -40] to +71] operating temperature range makes it ideal for data
communication equipments, mobile battery driven equipments, distributed
power systems, telecommunication equipments, mixed analog/digital
subsystems, process/machine control equipments, computer peripheral
systems and industrial robot systems.
