Hi Reliability, Ultra-Miniature, Isolated DC-DC Converters
-55ºC +85ºC Operating Temperature
Wide Input Range, All Units Shielded

Low Profile .300"
No Heat Sink or Electrical Derating Required

This series of high efficiency wide input range, encapsulated regulators come in 42 different models. Manufactured using high grade military components, this units will operate from -55º C to +85º C with no heat sink or electrical derating required. The 6 sided shielding and 32 pin DIP compatability combined with input/output isolation and the wide input range capabilities will meet your most stringent military requirements.
