Part Datasheet Review and Validation

flux

Reviewed the MGDS-04-J-C/M/S part against the GAIA Converter MGDM/MGDS-04 datasheet.
Result: The 9-pin schematic symbol matches the datasheet pinout: pins 1/2 = +Vi, 23/24 = -Gi, 11/12 = Go/common, 13/14 = Vo, 20 = On/Off. The footprint has 9 pads and the outline appears consistent with the 32.0 × 19.3 mm metallic DIL24-style package.
Key specs: 4 W isolated DC-DC converter, 16–40 VDC input, 5 V / 800 mA output, 1,500 VDC isolation, inhibit/on-off control, low-profile 7.5 mm case.
Mismatches / issues flagged:
  • Datasheet URL is already set, but it points to Datasheets360 rather than the apparent official/source PDF found from GAIA/Panatronic.
  • Pin Type properties are all “Unspecified”; these should ideally be Power Input, Power Output, Ground/Common, and Control.
  • Pin descriptions are encoded in designator names, but there are no explicit “Pin Description” properties on the terminals.

Fix the datasheet URL, add proper pin types/descriptions, then run ERC/DRC.

flux

I’ll update the part metadata and terminal pin properties, then run schematic/layout checks and report any remaining issues.

flux

The pin metadata is updated. ERC/DRC now only reports missing project documentation, so I’m adding a short verification note to clear that project-level check.

flux

Updated the Datasheet URL and Machine Datasheet URL to the source PDF, added proper terminal pin types/descriptions/groups for all 9 pins, and created a short verification note: part-verification-summary.
ERC/DRC/component checks now report no ERROR, WARNING, or OPEN findings.

Metallic Case - 1 500 VDC Isolation, Hi-Rel DC-DC Converter
The MGDS-04-J-C/M/S is a high-reliability 4 W isolated DC-DC converter module designed for demanding industrial, transportation, military, and aerospace applications. It belongs to the MGDS-04 series and features a 16–40 VDC input range (J input code), a regulated 5 VDC single output (C output code), and galvanic isolation between the input and output. The /S suffix indicates that the module undergoes screening and serialization for enhanced reliability and traceability, making it suitable for mission-critical systems.
Key Features 4 W isolated DC-DC converter Wide 16–40 VDC input voltage range Regulated 5 VDC single output High-efficiency power conversion Input-to-output galvanic isolation Designed for industrial, defense, aerospace, and transportation applications Built-in protection features (including short-circuit protection) Compact encapsulated module for PCB mounting /S option provides screening and serialization for improved quality assurance and traceability
