0.25mm Pitch / Fine-AWG Micro Coax
For fine-wire micro-coaxial assemblies used in denser routing and lighter interconnect layouts.
08 ASSEMBLIES
Fine-Pitch · Shielding · RF Process
When a micro-coax program is defined by how the assembly is built — the connector system it mates to, the pitch it routes at, the shielding it has to hold, or the RF and termination tolerances it must pass — these are the directions to compare. Each is a separate buying page with its own spec table and mating boundaries; this page groups them so you can move from a general requirement to the specific build that fits.
Assemblies in this cluster
08 REFFine-pitch micro-coax, shielding repeatability, RF/impedance integrity, and specialized termination are different ways of describing the same class of demanding assembly: high signal density in a small, controlled cross-section. A camera-module harness might be specified by its connector system; a high-speed link by its impedance and test records; a dense routing job by its pitch and shielding. The pages below let you enter from whichever constraint is driving the project, instead of forcing every program through one generic spec.
Each direction below is a dedicated page — connector compatibility, pitch and AWG, shielding, hybrid construction, and RF/impedance testing. Open the one that matches your locked requirement; if more than one applies, the connector or impedance page is usually the tighter place to start.
For fine-wire micro-coaxial assemblies used in denser routing and lighter interconnect layouts.
For projects that prioritize shielding repeatability and compact RF routing stability.
For projects where the connector system is already locked and mating, suffix, route, and version boundaries need review.
For fine-AWG micro-coax builds where stripping windows, terminal consistency, inspection checkpoints, and records matter.
For mixed-media assemblies that combine copper power, micro-coax signal, and fiber channels in one controlled harness.
For 50 ohm, 75 ohm, and 100 ohm micro-coax programs that need TDR, VNA, termination consistency, and test records.
For micro-coax projects where the Hirose DF36 connector system is already fixed and suffix variant, mating, wire gauge, and routing space need a compatibility review.
For micro-coax projects where the KEL USL / SSL connector system is already fixed and pitch step, variant, mounting height, and shield grounding need a compatibility review.
Most projects land on one page first and reference a second. A short way to decide where to start:
If the mating connector is already locked (I-PEX CABLINE, Hirose DF36, KEL USL/SSL), start from that connector page. Suffix variant, mating direction, wire gauge, and routing space are the boundaries that matter, and the page carries a compatibility table for them.
If the constraint is cross-section — ultra-fine wire, dense routing, low mounting height — the fine-pitch page is the cleaner entry, and it cross-links to the connector pages that support that pitch.
If EMI behavior, impedance target (50 / 75 / 100 ohm), or test records (TDR / VNA) gate the design, the shielding and RF-testing pages cover ground, coverage, and verification. These usually pair with a connector or pitch page rather than stand alone.
When copper power, coax signal, and fiber share one controlled harness, the hybrid page is the right starting point; it references the same termination and shielding discipline as the rest of the cluster.
