TF Card Product Range: 2GB to 128GB with Custom Speed Grades

Our current TF Card range covers six commonly requested storage capacities, with exclusive matched speed classes for each specification to fit different application scenarios:

The available capacity and speed grade should be selected according to the storage requirements, running speed standards and compatibility of the target device.

For bulk orders, please contact us with your required capacity, quantity, speed specification and application so we can confirm the current product configuration and availability.

We Manufacture New TF Cards for B2B Supply

Our TF Card product line is designed for customers who need a consistent source of new memory cards rather than used, refurbished or recycled products.

The cards are supplied as new products and undergo our strict quality-control and full-range testing process before shipment.

For B2B buyers, this provides a straightforward sourcing model for different capacity and speed grade requirements.

Instead of sourcing 4GB, 8GB, 16GB, 32GB, 64GB and 128GB TF Cards with different speed specifications from scattered suppliers, customers can discuss all specifications and customized requirements across our complete product range with one reliable supplier.

Our target customers include:

OEM manufacturers

Electronic equipment manufacturers

Distributors

Wholesalers

Importers

System integrators

Trading companies

Regional storage product suppliers

100% Tested TF Cards Before Shipment

Quality control is an important part of our TF Card production process.

Every card supplied through this product line is 100% tested before shipment according to our professional production and inspection procedures.

Depending on the product capacity and matched speed grade, our quality control covers accurate verification of storage capacity, sequential write speed, read speed and other core product characteristics to ensure compliance with official specification standards.

The objective is straightforward:

Produce → Test → Inspect → Pack → Ship

This standardized process helps eliminate defective, speed-unqualified or incorrectly configured cards, effectively reducing quality risks for customers' supply chain and terminal applications.

For customers with specific testing or inspection requirements for different speed-grade TF cards, please discuss the customized standards with our sales team before placing a bulk order.

Graded Speed TF Card for Diverse Compatible Applications

Our TF Card series adopts hierarchical speed grade configurations tailored to different storage capacities, including C8, C10, U2, U3 and U4 mainstream speed standards formulated by the SD Association.

Different speed grades correspond to distinct minimum sequential write speed and operating performance: C10 delivers a minimum sequential write speed of 10 MB/s, while U2, U3 and U4 higher-speed grades support faster data transmission, meeting the high-frequency reading and writing demands of high-definition recording, intelligent equipment and industrial scenarios.

Actual transfer performance can vary depending on the memory card, host device, controller, file system and operating conditions. For this reason, we recommend checking the speed specification compatibility of the target device before selecting a TF Card capacity and grade.

Our multi-speed graded TF cards can perfectly match compatible application scenarios with different speed and storage requirements.

Available TF Card Capacities & Corresponding Speed Specifications

4GB TF Card (C8 / C10)

The 4GB option with C8 and C10 dual speed grades is designed for applications with relatively low storage and speed requirements where a compact removable memory solution is required, fully adapting to low-power and basic electronic equipment operation.

8GB TF Card (C10 U2)

The 8GB TF Card adopts C10 U2 speed grade, providing stable and fast data transmission while offering additional storage capacity for compatible electronic devices and basic intelligent systems.

16GB TF Card (C10 U2)

16GB with C10 U2 high-stability speed grade is a practical option for applications requiring more storage and reliable daily data reading and writing, maintaining a compact removable memory format.

32GB TF Card (U2 / U3)

The 32GB TF Card supports U2 and U3 dual high-speed grades, providing higher-capacity and high-efficiency data transmission options for compatible applications requiring continuous local data storage and real-time recording.

64GB TF Card (U2 / U4)

64GB large-capacity TF card is equipped with U2 and U4 high-speed specifications, offering greater storage capacity and ultra-fast transmission speed for applications where long-time video recording and large-scale data storage are required.

128GB TF Card (U3 / U4)

The 128GB TF Card is the highest-capacity option currently available in this product range, adopting U3 and U4 top-level speed grades, suitable for high-end compatible devices requiring large-capacity removable storage and high-frequency fast data transmission.

Device compatibility and matching speed grade requirements should always be confirmed before selecting a specific capacity.

Neutral Packaging TF Cards for Distributors

Our TF Cards with all capacities and speed grades are available with neutral packaging for B2B customers.

Neutral packaging is useful for distributors and wholesalers who do not want to purchase consumer-oriented retail packaging from a fixed brand.

This provides greater flexibility for:

Distribution

Wholesale

OEM supply

Regional sales

Import and export

Equipment integration

If your business requires a specific packaging configuration for different speed-grade TF cards, please provide the requirement when requesting a quotation.

Bulk TF Card Supply for OEMs and Wholesalers

We focus on B2B TF Card supply rather than individual consumer retail sales, supporting customized bulk procurement of all capacities and matched speed grades.

For bulk purchasing, customers can freely match different capacities and speed grades according to their application scenarios and sales requirements.

Typical purchasing information includes:

Required capacity and speed grade

Order quantity

Target application

Packaging requirement

Destination country

Expected delivery schedule

This information allows us to evaluate the appropriate product configuration and provide an accurate quotation.

TF Card Applications

TF Cards, also commonly referred to as Micro SD Cards, are used as removable storage in a wide range of compatible electronic products. Different capacities and speed grades can be precisely matched to diverse application scenarios.

Dash Cameras

Compatible dash cameras can use matched-grade TF Cards for local video storage. It is recommended to select U2/U3 high-speed grades for high-definition continuous recording scenarios to avoid frame drop and recording failure.

CCTV and Surveillance

High-speed grade TF Cards (U2 and above) are suitable for local storage of compatible surveillance cameras and monitoring equipment, supporting 24-hour uninterrupted video storage.

GPS and Navigation Equipment

Stable C10 and U2 grade TF Cards are applicable to navigation and GPS devices for storing map data and daily local data.

Portable Electronics

Multi-grade TF Cards provide flexible removable storage options for all kinds of compatible portable electronic devices, meeting basic and high-speed storage demands.

Embedded Systems

High-speed U3/U4 grade TF Cards can perfectly adapt to compatible embedded systems requiring high-frequency data reading and writing.

Consumer Electronics

Our full-series graded TF Cards are widely used in compatible consumer electronic devices requiring compact removable storage, covering low, medium and high-speed application scenarios.Application compatibility and matching speed grade should be confirmed with the equipment manufacturer before purchasing.

TF Card vs. Micro SD Card

TF Card and Micro SD Card are commonly used terms for the same compact removable memory card form factor.

TF, or TransFlash, was the original name associated with the format. The format later became part of the SD Card family and is commonly known as microSD.

For international sourcing, buyers may therefore search for either:

TF Card

Micro SD Card

TF Memory Card

Micro SD Memory Card

Our product page uses both TF Card and Micro SD Card terminology so international buyers can find the appropriate graded speed products more easily.
