I-PEX MHF I micro-coaxial RF connector engineering reference

I-PEX MHF I manufacturer feature-table family: smt reference size: 3.1 x 3.0 mm; cable options: Micro-coax OD 0.81, 1.13, 1.32, 1.37, 1.8 or 2.0 mm; selection depends on plug type; rf range: Up to 9 GHz; published plug VSWR limits depend on cable diameter. Only the I-PEX MHF I manufacturer feature-table family feature table; no exact individual part properties or mating approval are established.

MHF I family construction and cable-selection reference, without selecting a particular plug or receptacle

Mating boundary

Shape is not the verdict.

Use the exact manufacturer mating component, terminal/cable and current drawing. Only the I-PEX MHF I manufacturer feature-table family feature table; no exact individual part properties or mating approval are established. A source-described lock, key or dimensional resemblance is not an approved equipment connection.

How to read this profile

Textual manufacturer construction/configuration facts and explicitly labelled dimensions only. No mating-face, termination-side, contact-number layout or PCB footprint is reconstructed.

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Unknowns stay unknown.

These are manufacturer-family feature rows, not verified individual characteristics of 20279-001E-03 or 20278-112R-13. No different part values are combined.
Source SMT size is a labelled reference tuple with unnamed axes; it is not entered as connector-body dimensions or a fabrication footprint.
Mating heights vary by plug/lock variant; no single height or lock state is assigned from the multi-column comparison. Cable, plug and receptacle selection and RF performance remain exact-assembly dependent.
No numbered electrical contact assignment, hardware test, specimen measurement, fabrication approval or complete application rating/derating is established.
