Notes:
1. UWR-3.3/4850-D48A (18-75V input, curve A) and UWR-3.3/4850-D12A (9-36V input, curve A)
will derate curve AA if used over the limited input ranges of 20-60V or 10-30V, respectively.
For "D5A" and "D12A" models, the
case is connected to pin 2 (–VIN).
For "D48A" and "D48E" models, the
case is connected to pin 1 (+VIN).
2. "D48A" models (18-75V input ranges) that derate along curve B will derate along curve BB
if used over the more limited input range of 24-60V.
Components are shown for reference only.
