TF-115K 自弹式MicroSD卡(TF卡)SMD卡座 产品概述

一、产品核心定位

TF-115K是讯普(XUNPU)推出的自弹式MicroSD卡(TF卡)专用卡座,采用SMD表贴封装,以「轻薄化、高可靠、易集成」为核心设计目标,适配各类需要MicroSD卡扩展存储的小型化电子设备,兼顾消费电子的便携性与部分工业场景的环境适应性。

二、关键技术参数详解

TF-115K的核心参数完全匹配MicroSD卡的物理与电气要求,关键参数如下:

  • 卡连接方式:自弹式(按压弹起),无需工具即可完成卡的插入/取出,操作便捷;
  • 兼容卡类型:MicroSD卡(TF卡),支持标准MicroSD/SDHC/SDXC卡(容量兼容至主流规格);
  • 连接器类型:直插式卡座(本体垂直安装);
  • 本体尺寸:最大高度仅1.8mm,宽度/长度适配MicroSD卡标准尺寸(参考讯普官方 datasheet);
  • 封装形式:SMD(表面贴装),8pin引脚(对应MicroSD卡电气触点);
  • 工作温度范围:-45℃ ~ +85℃,覆盖低温户外与高温车载等场景;
  • 可靠性参数:插拔寿命≥10000次(循环测试),接触电阻≤30mΩ(常态),绝缘电阻≥100MΩ(DC500V),耐压AC500V/1min(无击穿)。

三、设计特点与核心优势

1. 轻薄化适配小型设备

1.8mm的本体最大高度是核心亮点,可完美适配智能手环、智能手表等厚度敏感的便携设备,避免因卡座占用空间影响产品形态。

2. 自弹式结构提升操作效率

采用成熟的按压弹起机构:插入时轻按锁定,取出时再次按压自动弹出,无需手动抠取,解决小型设备中TF卡取出困难的痛点,同时减少卡体磨损。

3. SMD封装兼容自动化生产

SMD表贴封装符合SMT标准,可通过贴片机批量生产,生产效率远高于插件式卡座,降低人工成本与焊接不良率。

4. 高可靠接触设计

触点采用镀金工艺(或镀锡+抗氧化处理),减少氧化腐蚀风险;触点结构优化,插拔时接触压力均匀,避免虚接或接触不良,保证数据传输稳定。

四、封装与安装注意事项

TF-115K的SMD封装需遵循标准贴装流程:

  • 贴装前:确认PCB焊盘尺寸与引脚匹配(参考讯普封装图纸),焊盘需清洁无氧化;
  • 回流焊参数:峰值温度230℃~250℃(时间≤10s),升温速率≤3℃/s,降温速率≤2℃/s,避免温度冲击导致卡座变形;
  • 安装后检测:检查自弹机构是否顺畅(按压无卡顿),触点是否完全焊接,用万用表测试接触电阻是否符合要求。

五、环境适应性与可靠性验证

TF-115K通过多项可靠性测试:

  • 温湿度循环:-40℃~+85℃、湿度95%RH,循环100次后性能无衰减;
  • 振动测试:10~2000Hz、加速度1G,持续2小时无接触不良;
  • 冲击测试:10G(峰值)、持续11ms(半正弦波)无结构损坏;
  • 插拔寿命:10000次循环后,触点电阻变化≤10%,自弹机构正常工作。

六、典型应用领域

TF-115K适用于以下场景:

  1. 消费电子:智能手环、智能手表、便携蓝牙音箱、MP3/MP4、电子书阅读器;
  2. 物联网终端:小型环境传感器、智能家居摄像头、智能门锁(存储日志);
  3. 车载电子:迷你行车记录仪、车载蓝牙适配器、胎压监测终端;
  4. 工业手持设备:小型数据采集器、条码扫描枪、便携式检测仪器。

总结

TF-115K作为讯普高性价比自弹式TF卡座,凭借轻薄设计、可靠性能与易集成性,成为小型化电子设备存储扩展的优选方案,可满足不同场景下的存储需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
