Engineering & Procurement Considerations

What Engineers Should Consider When Selecting a 50Ω 38AWG Micro-Coaxial Cable

A micro-coaxial cable is designed for compact electronic systems where high-frequency signal transmission, controlled impedance, small outer diameter, shielding and flexible routing are important.

This HOTTEN configuration combines a 50Ω characteristic impedance, 38AWG conductor, PET structure and approximately 0.43mm outer diameter, making it particularly relevant to space-constrained electronic applications such as mobile phones, laptops, tablets and compact coaxial harnesses.

The cable should be evaluated as a complete electrical and mechanical interconnect because conductor geometry, dielectric construction, shielding, length and termination can all affect the final performance.

Published Product Configuration

The 50Ω, 38AWG and 0.43mm combination should be retained as the key product-identification parameters for this page.

Key Engineering Requirements

50Ω Impedance Considerations

50Ω characteristic impedance is one of the most important technical entities for this product.

When specifying a 50Ω micro-coaxial cable, engineers should consider the relationship between:

Conductor Diameter + Dielectric Geometry + Shielding + Cable Construction

The target impedance should be defined together with its acceptable tolerance and test conditions.

Procurement teams should provide:

• Target impedance

• Impedance tolerance

• Measurement conditions

• Cable length

• Connector configuration

• Required signal frequency, where applicable

The 50Ω requirement should be evaluated at the complete cable-assembly level when connectors are included.

38AWG Conductor Considerations

The 38AWG conductor provides a fine-gauge solution for compact electronic applications.

Before production, customers should specify:

• Conductor material

• Silver plating requirements

• AWG

• Stranding structure

• Insulation

• Flexibility requirements

• Electrical requirements

The current product is identified with silver-plated copper as the conductor material.

0.43mm Outer Diameter Considerations

The approximately 0.43mm OD is another strong engineering identifier.

For compact electronic assemblies, customers should clarify:

• Target OD

• Maximum allowable OD

• OD tolerance

• Routing clearance

• Connector entry dimensions

• Minimum bending radius

• Strain-relief requirements

For mobile phones, laptops and tablets, even a small change in cable diameter can affect internal routing and mechanical assembly.

PET Structure Considerations

The product is identified with a PET construction.

When specifying PET, engineers should evaluate:

• Dielectric requirements

• Cable dimensions

• Flexibility

• Mechanical protection

• Heat exposure

• Routing conditions

• Compatibility with the complete coaxial structure

The PET layer should be considered together with the conductor and shield because the complete geometry influences impedance and mechanical characteristics.

Signal Integrity Considerations

For a 50Ω micro-coaxial cable, signal integrity depends on the consistency of the entire transmission path.

Relevant factors include:

• Characteristic impedance

• Conductor geometry

• Dielectric construction

• Shielding

• Cable length

• Connector termination

• Bend conditions

• Routing near other electronic components

The final cable should therefore be selected according to the target device's electrical interface rather than only by conductor size.

Shielding and EMI Control

The micro-coaxial structure provides a shielded signal path around the conductor.

For OEM applications, engineers should define:

• Shield material

• Shield coverage

• Grounding method

• Shield termination

• Connector-side shield continuity

• Required EMI performance

The final shielding structure should be matched to the frequency, signal environment and system architecture.

Flexibility and Mechanical Routing

A 0.43mm micro-coaxial cable may be routed through highly constrained electronic assemblies.

Important mechanical considerations include:

• Minimum bending radius

• Repeated bending

• Cable exit direction

• Routing path

• Connector position

• Strain relief

• Assembly method

The cable should maintain its electrical and coaxial structure during the intended bending and assembly process.

Typical Application Considerations

The product is positioned for:

• Mobile phones

• Laptops

• Tablets

• Coaxial harnesses

For these applications, the engineering priorities can differ:

Mobile Devices:
Very small OD, dense routing and compact connector integration.

Laptop / Tablet Systems:
Flexibility, internal routing and repeated movement around device structures.

Coaxial Harnesses:
Controlled impedance, shielding, connector configuration and multi-cable organization.

The final cable design should be matched to the actual device architecture.

Connector and Termination Considerations

For a small 50Ω micro-coaxial cable, connector selection is an important part of the complete signal path.

Customers should provide:

• Connector manufacturer

• Connector series

• Part number

• Mating interface

• Contact configuration

• Pin assignment

• Connector orientation

• Termination method

• Strain relief requirements

A connector part number or drawing is preferred to a generic connector description because connector geometry can affect the final signal path.

Key Procurement Parameters

When sourcing a 50Ω 38AWG micro-coaxial cable, procurement teams should confirm:

OEM Customization

HOTTEN supports customized micro-coaxial cable solutions according to customer requirements.

Customization may include:

• Conductor material

• AWG

• Impedance

• Cable diameter

• Dielectric structure

• Shielding

• Cable length

• Connector

• Pin assignment

• Termination

• Prototype samples

• Mass-production configuration

For OEM projects, the final cable should be designed around the customer's device interface and mechanical routing requirements.

Supplier Evaluation Checklist

When evaluating a supplier for a 50Ω 38AWG micro-coaxial cable, procurement teams should consider:

① Micro-Coaxial Manufacturing Capability
Can the supplier consistently manufacture fine-gauge micro-coaxial structures?

② Impedance Control
Can the supplier maintain the specified 50Ω impedance and required tolerance?

③ Small-Diameter Manufacturing
Can the supplier maintain approximately 0.43mm OD with stable dimensional control?

④ Fine-Wire Processing
Can the supplier consistently process 38AWG silver-plated copper conductors?

⑤ Connector Integration
Can the supplier provide the specified miniature RF/coaxial connector and termination?

⑥ Prototype-to-Mass-Production Support
Can the supplier support engineering samples and recurring production?

Recommended RFQ Information

For faster engineering evaluation and quotation, customers should provide:

• Target impedance and tolerance

• 38AWG or required conductor size

• Conductor material

• Target OD and tolerance

• PET / dielectric requirement

• Shielding requirement

• Cable length

• Minimum bending radius

• Connector part number

• Pinout / termination requirements

• Device application

• Cable drawing

• Prototype quantity

• Expected production volume

• Required electrical and mechanical testing

For this particular product, the most useful RFQ combination is:

50Ω + 38AWG + 0.43mm OD + PET + Cable Length + Connector + Application
