AI summary

WRA1205ST-3WR2 is a compact 3 W isolated DC-DC converter for converting a 12 V nominal input into regulated ±5 V rails.

Best for

12 V nominal industrial electronics
Instrumentation requiring isolated dual supply rails
Compact communications and control equipment

Avoid if

The input is outside 9–18 VDC
The application needs more than 3 W output power
No minimum output load can be provided

Check before use

Confirm the exact WRA_ST package and PCB footprint
Apply the temperature derating shown in the datasheet
Use the recommended external capacitors and observe maximum capacitive-load limits
