Definition: A flat cable (also known as a ribbon cable) is a type of electrical cable with multiple parallel conductors bonded together in a flat, wide strip.

Common Uses: Internal connections in computers and electronics (e.g., IDE, floppy drives, IDC connectors).

Key Features:

• Flat, flexible design
• Multiple conductors (typically 4 to 80+ wires)
• Pitch: Commonly 1.27 mm (0.05 inch)
• Terminated with IDC (Insulation Displacement Connector) or crimped headers

Types:

• Ribbon Cable (standard, unshielded)
• FPC (Flexible Printed Circuit) – thinner, used in compact devices
• FFC (Flexible Flat Cable) – integrated conductors, no insulation between wires

Note: Ensure correct orientation (usually marked with red stripe on pin 1 side).
