Introduction to DDR4 SO-DIMM 260 Pin

Introduction to DDR4 SO-DIMM 260 Pin Connectors

1. Background of DDR4 SO-DIMM

DDR4 SO-DIMM (Small Outline Dual In-line Memory Module) is a memory module standard designed for laptops, industrial PCs, embedded systems, and compact servers. Compared to traditional DIMM, SO-DIMM offers a smaller footprint, making it ideal for space-constrained designs. The 260-pin configuration is the standard for DDR4, enabling higher bandwidth, lower power consumption, and more stable signal transmission.

2. Key Features of 260 Pin SO-DIMM

  • 260 contacts, compared to DDR3 SO-DIMM’s 204 pins, delivering improved data transfer capability.

  • Low operating voltage: 1.2V, ensuring reduced power consumption.

  • High data rate: from 2133 MT/s up to 3200 MT/s and beyond.

  • Application scope: laptops, mini PCs, industrial computers (IPC), networking devices, and edge computing systems.

3. Height Variants (4.0H, 5.2H, 8.0H, 9.2H)

DDR4 SO-DIMM connectors are designed with multiple height options to accommodate different structural requirements and thermal considerations:

  • 4.0H (Low profile)- part no. M30-C105-00001
    Optimized for ultra-slim laptops and compact devices where space is critical.

  • 5.2H (Standard profile)- part no. M30-C105-00003
    Widely adopted for laptops and IPCs, balancing space efficiency and mechanical strength.

  • 8.0H (Reinforced height)- part no. M30-C105-00004
    Provides higher durability and insertion endurance, commonly used in industrial or embedded applications.

  • 9.2H (High-strength design)- part no. M30-C105-00005
    Suitable for high-reliability environments requiring more clearance and thermal management, such as servers or advanced industrial systems.

4. Technical & Reliability Highlights

  • Durable contact design: High-conductivity copper alloy with gold plating ensures stable signal transmission over long-term use.

  • Shock & insertion resistance: Enhanced mechanical stability across all height variants for diverse applications.

  • JEDEC compliant: Fully aligned with DDR4 SO-DIMM standards for cross-platform compatibility.

5. Application Scenarios

  • Consumer electronics: laptops, mini PCs, all-in-one PCs.

  • Industrial computing (IPC): factory automation controllers, edge computing systems.

  • Embedded systems: medical equipment, networking hardware.

  • High-performance computing: small form factor servers and data center solutions.
