AI summary

VRB1203S-6WR3 provides an isolated, regulated 3.3 V rail from a 9-18 VDC input at up to 6 W in a SIP-8 through-hole module.

Best for

Generating an isolated 3.3 V rail from a nominal 12 V bus
Through-hole industrial and instrumentation designs

Avoid if

The application needs operation below 5% load while maintaining specified ripple
A documented 3000 VDC isolation rating is mandatory without part-specific confirmation

Check before use

Confirm actual label pinout
Validate thermal derating above 71 C ambient
Keep capacitive loading within 2200 uF
