URB4812YMD-5WR3 is a compact DC-DC power module with an input range of 18–75 V (typical 48 V rail) and a single 12 V output delivering up to 416 mA. Designed for harsh industrial environments, it provides galvanic isolation between input and output, reliable protection, and a package and pinout consistent with the UR(B)_YMD family to facilitate quick design-in and interchangeability.
Key Features
- Input: 18–75 V wide-range
- Output: 12 V single output, 416 mA
- Isolation: galvanic isolation between input and output
- Package: URB4812YMD-5WR3, footprint consistent with URB_YMD family (approx. 25.4 × 25.4 × 11 mm)
- Protection: overcurrent and short-circuit protection; thermal considerations per datasheet
- EMC: external filtering networks recommended by vendor to meet ripple and noise targets

Mechanical and Pinout (Representative)
Fixed pinout with a consistent footprint across UR(B)_YMD family. See the datasheet or actual product label for exact pin definitions.
Notes on EMC and Filtering
Follow vendor recommendations for external EMC filtering to meet ripple and noise targets. Typical guidance includes appropriate capacitors and inductors on the input and output stages for a single 12 V output configuration.
Usage Guidance
Use with proper input filtering, observe minimum load requirements for stable operation, and ensure total external capacitance does not exceed the recommended limits. Mechanical mounting should adhere to the provided footprint for reliability.
