Transcend 4 GB MicroSD microSD, Class 10

Transcend microSD, 4GB Memory Size, Class 10 Speed Class Rating - TS4GUSD300S

This microSD is a Compact removable memory card designed to expand storage for electronic and automation equipment. It offers 4GB capacity using Planar NAND technology and operates across a wide temperature range suitable for many industrial-adjacent environments while meeting recognised conformity standards.

Features and Benefits:

• 4GB capacity supports modest data logging and firmware storage needs
  Class 10 rating enables consistent sustained write speeds for recording
  2D NAND construction provides standard flash reliability and longevity
  Operates down to -25°C for use in cooler ambient conditions
  Withstands up to 85°C for high-temperature operating scenarios

Applications

• Suitable for data logging in automation controllers and PLCs
  Ideal for firmware updates in embedded electronic systems
  Used with diagnostic tools for field equipment fault capture
  Can be used for storing configuration files in electrical panels
  Used for short-term archival of sensor outputs in mechanical testing

What type of flash memory does it use and why does that matter

It employs 2D NAND, which offers predictable write/erase behaviour and straightforward compatibility with standard memory controllers.

How does the speed class affect recording tasks

The Class 10 rating ensures a minimum sustained write performance suited to continuous logging and video-capture workflows at modest resolutions.

Can it be deployed in environments with thermal fluctuation

Yes, it supports operation between -25°C to 85°C, accommodating both low-temperature storage areas and elevated-process temperatures.
