Multi Conductor Flat Cable Manufacturer
Multi-conductor flat cable is a type of cable featuring multiple conductors arranged in parallel and encased in insulating material to form a ribbon-like structure. It offers benefits such as neat wiring, space savings, and stable signal transmission. As a professional multi-conductor flat cable manufacturer, Linkwings provides both standardized products and customized solutions to customers worldwide.
What is a Multi-Conductor Flat Cable?
A multi-conductor flat cable consists of multiple conductors arranged in parallel at fixed intervals, collectively encased within an insulating layer to form a flat ribbon configuration. Unlike traditional round cables, this design ensures more uniform conductor distribution, resulting in tidy wiring and consistent thickness. This configuration delivers exceptional space utilization in equipment with limited room. Additionally, maintaining consistent geometric spacing between conductors effectively minimizes signal crosstalk and delay variations, ensuring stable electrical performance.
In practical applications, multi-conductor flat cables are commonly used in laptops, displays, printers, automotive electronics, and industrial control systems. They support not only power transmission but also high-speed data signal transfer. Due to their flexibility, space-saving design, and compatibility with standardized interfaces, an increasing number of engineers prioritize multi-conductor flat cables as a reliable wiring solution when designing compact electronic devices.

| Multi Conductor Flat Cable | Parallel conductors in flat, ribbon-like profile; optional shielding | Low crosstalk, low skew, supports high-speed signals | Flexible, thin (0.1–0.3mm), good bend life | Laptops, LCD displays, automotive, medical, robotics |
| Single Conductor Cable | Single copper conductor with insulation | High current capacity, simple electrical path | Strong, durable, less flexible | Power supply, grounding, basic wiring |
| Round Cable | Bundled conductors inside a round jacket | Moderate EMI protection, supports power & signal | High tensile strength, durable, space-consuming | Industrial control, motors, power transmission |
| Ribbon Cable | Multiple parallel wires laminated together in flat form | Good for low-frequency signals, higher crosstalk | Flexible but less robust, moderate durability | Early computer interfaces, printers, basic electronics |
- Multi-conductor flat cable: Most suitable for scenarios with limited space requiring high-speed signal transmission, such as consumer electronics and automotive electronics.
- Single-conductor cable: Primarily used for power and grounding, featuring a simple structure but unsuitable for multi-channel signal transmission.
- Round cable: Offers advantages in strength and durability, making it more suitable for long distances or harsh environments.
- Ribbon cable: The earliest form of parallel wiring, suitable for low-speed signals. It has been progressively replaced by multi-conductor flat cable in high-speed and complex environments.
Comparatively, multi-conductor flat cable offers significant advantages in signal integrity, space utilization, and flexibility, making it the preferred solution for modern electronic and industrial applications.
FAQs about Multi Conductor Flat Cables
1. Can Multi Conductor Flat Cable carry high currents?
Answer: Generally, Multi Conductor Flat Cable is better suited for low currents and signal transmission. Its current-carrying capacity depends on the conductor’s AWG rating and heat dissipation conditions. For example, AWG28 is suitable for approximately 1A, while AWG20 can handle 3–5A. For high-current applications, we recommend using Round Cable or custom high-current flat cables.
2. Is Multi Conductor Flat Cable suitable for high-speed signal transmission?
Answer: Yes. Due to its parallel conductor arrangement and consistent spacing, it ensures low crosstalk and minimal delay skew, making it highly suitable for high-speed interfaces such as LVDS, MIPI, HDMI, and USB. For scenarios requiring higher signal integrity, shielded variants are available.
3. What are the common pitches and conductor counts for multi-conductor flat cables?
Answer: Common pitches include 0.5mm, 1.0mm, 1.25mm, and 2.54mm. Conductor counts typically range from 4 to 80 cores. Specific selection depends on the interface standards and wiring requirements of the application equipment.
4. What is the operating temperature range for Multi Conductor Flat Cable?
Answer: Depends on the insulation material:
- PVC: -20°C to +80°C
- PET: -40°C to +105°C
- PI (Polyimide): -40°C to +125°C; military-grade variants can withstand up to +200°C
Therefore, PI-based Multi Conductor Flat Cable is recommended for high-temperature environments.
