Technical Summary
Starway Technology manufactures high-temperature power resistor cable assemblies for AI server and high-reliability electronic equipment applications. This product uses a Molex Mini-Fit Jr. plug housing, dual row, 2 circuits, UL 94V-2, natural color, without panel mounting ears, with customer-specified part number 39-01-2023.
The resistor side uses aluminum housed resistors with aluminum extrusion to improve heat dissipation. Because power resistors may generate high temperature during operation, the cable uses TGGT-400 1.25SQMM high-temperature wire, rated for 400°C and 600V AC. The conductor uses nickel-tin alloy plated copper with a stranded diameter of 1.50mm, protected by three fiberglass layers, resulting in an overall outer diameter of approximately 3.00mm.
The crimping process is a critical control point because poor crimping may local heating and increase the risk of connector damage. For this project, the conductor compression ratio was defined at 80–90%, and metallographic cross-section review was used to help verify terminal crimp quality before production ramp-up.

Molex Mini-Fit Jr. Connector Side
The connector side uses a Molex Mini-Fit Jr. plug housing, dual row, 2 circuits, UL 94V-2, without panel mounting ears, natural color. This connector interface is used as the harness connection point for the aluminum housed resistor assembly.
During manufacturing, the connector, terminals, wire gauge, crimp condition, conductor compression, housing insertion, contact retention, and final mating-related requirements are reviewed based on customer drawings, connector specifications, and approved production documents.
Crimped high-temperature wire terminal with conductor compression control for heat-risk reduction.
Crimp Terminal Quality and Heat Risk Control
Terminal crimping is one of the most critical process points in this product. If the terminal is not crimped correctly, local resistance may increase, which can localized heating and raise the risk of connector damage or burning under load.
To reduce this risk, the crimping process was developed with reference to crimp workmanship principles. The conductor compression ratio was defined at 80–90%, and metallographic cross-section review was used to help verify that the crimped terminal structure meets the intended process quality.

TGGT-400 High-Temperature Wire Selection
Because the aluminum housed resistor may generate high temperature during operation, wire selection is an important design and manufacturing decision. This product uses TGGT-400 1.25SQMM high-temperature wire, which is suitable for high-temperature environments and is rated for 400°C and 600V AC.
The conductor uses nickel-tin alloy plated copper with a stranded diameter of approximately 1.50mm. The conductor is protected by three fiberglass layers: an inner white insulation layer, a middle white braided layer, and an outer white/red braided layer. The finished wire outer diameter is approximately 3.00mm.
From Low-Volume Demand to Production Ramp-Up
This product is suitable for the Prototyping & Low-Volume category because the project started with lower customer demand and later increased as the customer's production capacity expanded. Starway Technology supported the transition by adjusting the production line, refining crimping control, stabilizing electrical testing, and preparing repeatable assembly steps for higher-volume output.

Common Manufacturing Risks for High-Temperature Power Resistor Assemblies
Local Heating from Poor Crimping
If terminal crimping is unstable, local resistance may increase and heat concentration, which can damage the connector or reduce product reliability.
Incorrect Wire Temperature Rating
Standard wire may not be suitable near high-temperature resistors, so high-temperature wire selection must match the thermal environment.
Insufficient Heat Dissipation
Aluminum housed resistors use aluminum extrusion to support heat dissipation. Poor assembly fit may reduce thermal and mechanical performance.
Packaging and Handling Damage
Aluminum housed parts and connector assemblies may be damaged by collision, so individual packaging is used to reduce handling risk.
IPC-Based Workmanship Approach
As an IPC Association member, Starway Technology applies IPC-based workmanship principles across custom wire harness and electrical assembly manufacturing, including wire cutting, insulation stripping, terminal crimping, soldering, connector assembly, electrical testing, packaging, and final inspection.
Relevant workmanship references may include IPC/WHMA-A-620 Chapter 3 for wire preparation and crimping-related workmanship, together with project-specific inspection principles for high-temperature wire handling, crimp compression verification, soldering, contact testing, and final cable assembly quality control.
These references do not replace customer drawings, Molex connector specifications, resistor manufacturer requirements, TGGT-400 wire specifications, AI server system requirements, or project-specific test criteria. Instead, they provide a workmanship framework that helps strengthen inspection awareness, production control, and technical communication between the customer and manufacturer.
Customer Value
Controlled high-temperature resistor cable assembly manufacturing helps customers reduce thermal connection risk, validate crimp quality, confirm high-temperature wire suitability, improve aluminum housed resistor assembly consistency, and support production ramp-up as customer demand increases. This approach is especially useful for AI server applications, thermal-load equipment, industrial electronics, high-power systems, and other high-reliability applications where heat, resistance, and connection stability must be carefully controlled.
