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.
