Specifications (Core Operating Area)
The RW series with 2:1 input voltage ranges and max. height of 7,0 mm has been designed for the telecom - and
industrial automation markets. They are particularly aimed at applications where pcb-space is at a premium, still
requiring industrial standard pinning. The converters supply the full 3 Watts without additional heat-sinks over the
temperature range -40C to +85C.
