DESCRIPTION

The DCBYB100 series of isolated DC/DC converters offer

100 watts of output power in a 2.40” x 2.28” x 0.5” package

with standard pinout case. This series consists of single

output models with a wide 4:1 input voltage range. Each

model in this series has high power density, high efficiency,

and short circuit, over voltage, and over temperature

protection. Please call factory for order details.
