Hi Reliability, Ultra-Miniature, 0.2" ht. 
Isolated DC-DC Converters

This series of unregulated DC-DC converters offer you a 0.200" tall package. 144 different models are available and all offer very low current consumption to operate in battery driven circuits. Isolated, single and dual outputs will operate from -25º C to +70º C with no heat sink or derating required. Built-in output capacitors and 4 convenient input voltages also help in simplifying your design, and with the addition of our new DIP package, board layout and assembly is simplified.
