Overview
The URB4805YMD-5WR3 converts a wide input voltage from 18 V to 75 V (typical 48 V rail) to a single 5 V output rated at 1.0 A. This rugged, isolated DC-DC power module is designed for industrial applications and offers galvanic isolation, robust protection, a compact 25.4 × 25.4 × 11 mm footprint, and a consistent pinout to simplify design-in and interchangeability within the UR(B)_YMD family.
Key Features
- Input: 18–75 V wide-range (typical 48 V systems)
- Output: 5 V at 1000 mA (single output)
- Isolation: galvanic isolation between input and output
- Package: URB4805YMD-5WR3 with dimensions 25.4 × 25.4 × 11 mm
- Protection: overcurrent and short-circuit protection; thermal considerations per datasheet
- EMC: designed to operate with recommended external filtering networks for ripple and noise targets

Mechanical and Pinout (Representative)
Fixed pinout with a consistent footprint across UR(B)_YMD family. Refer to the datasheet for exact pin definitions and layout. Visuals below illustrate the bottom and side views for the single-output variant.
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 in the input and output stages, tailored to a single 5 V output configuration.
Usage Guidance
Integrate with proper input filtering, observe minimum load requirements for stable operation, and verify that total external capacitance does not exceed the recommended limits. Ensure mechanical mounting adheres to the provided footprint for reliability.
