URB4815YMD-5WR3 is a compact dc-dc power module featuring an input range of 18–75 v (typical 48 v rail) and a single 15 v output delivering up to 333 ma. Built for harsh industrial environments, it provides galvanic isolation between input and output, robust protection, and a package and pinout aligned with the URB_YMD family to support rapid design-in and interchangeability.
Key Features
- Input: 18–75 v wide-range
- Output: 15 v single output, 333 ma
- Isolation: galvanic isolation between input and output
- Package: URB4815YMD-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 URB_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 15 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.
