TS45055A 薄膜开关产品概述

TS45055A是首韩(SHOU HAN)品牌推出的一款超轻薄SMD立贴薄膜开关,针对小型化电子设备的轻触操作需求设计,凭借紧凑尺寸、稳定性能及易安装特性,成为便携电子、小型仪器等领域的实用选择。

一、产品核心定位与优势

TS45055A聚焦小型化低功耗设备的轻触按键需求,核心优势体现在3个维度:

  1. 超轻薄适配:整体尺寸仅4.5mm×4.5mm×0.55mm,高度不足0.6mm,可嵌入指甲盖大小的空间,完美匹配智能手环、迷你遥控器等超薄设备;
  2. 自动化友好:采用立贴(SMD)接片引脚封装,支持SMT自动化贴装,大幅提升生产效率,降低人工焊接成本;
  3. 手感与寿命平衡:250gf±50gf(约2.5N)的作用力平衡了“误触概率”与“操作手感”,3万次工作寿命满足普通用户长期使用(每天10次可用8年以上)。

二、关键参数详细解读

TS45055A的参数精准匹配小型设备的低功耗、紧凑化需求,具体如下:

1. 电气性能

  • 额定电压:12V DC(仅适配低压电路,避免过载);
  • 触点电流:50mA(低电流设计,适合信号传输/功能切换,不支持大电流功率控制);
  • 电路结构:单刀单掷(SPST)——仅实现“通/断”基础功能,适合电源开/关、模式切换等场景。

2. 机械参数

  • 尺寸:4.5mm(长)×4.5mm(宽)×0.55mm(高)——长宽一致,安装布局灵活;
  • 作用力:250gf±50gf(轻脆手感,按压不费力,频繁操作不易疲劳);
  • 寿命:3万次(触点无明显氧化/磨损,满足日常使用强度)。

3. 安装与外观

  • 安装方式:立贴(SMD)接片引脚,不带支架——无额外焊接空间,贴合PCB板更牢固;
  • 外观:黄色薄膜(无实体按钮),无带灯设计——黄色标识清晰,薄膜结构防尘性优于实体按钮,无灯降低功耗适配电池设备。

4. 环境适应性

  • 工作温度:-20℃~+70℃——覆盖室内(室温)及户外温和环境(如夏季户外、冬季室内),满足多数消费电子场景。

三、结构设计与安装特点

TS45055A采用薄膜层叠结构(区别于传统金属弹片):按压时薄膜形变实现触点导通,回弹迅速且无卡顿;立贴SMD封装的优势在于:

  • 与PCB板贴合紧密,抗振动性能好,适合移动设备(如智能手环);
  • 不带支架进一步压缩体积,避免额外零件占用空间,让设备更轻薄。

四、典型应用场景

结合参数特性,TS45055A适合以下场景:

  1. 便携穿戴:智能手环、智能手表的功能切换键(心率监测、运动模式);
  2. 小型消费电子:迷你遥控器(电视盒子、投影仪)、电子玩具(微型机器人)、便携充电宝的电源键;
  3. 医疗小型设备:便携血糖仪、血氧仪的操作按键(数据查询、模式切换);
  4. 工业小型模块:小型传感器节点、微型PLC的测试键、状态切换键。

五、使用注意事项

  1. 禁止用于大电流设备(如电机控制、大功率LED),避免触点过载损坏;
  2. 焊接温度需控制在260℃以下,单次焊接时间不超过3秒,防止薄膜结构变形;
  3. 避免长期暴露在极端温度(>70℃或<-20℃),以免影响寿命。

TS45055A以“轻薄、稳定、易安装”为核心,精准匹配小型化低功耗设备的按键需求,是便携电子、医疗仪器等领域的高性价比选择。

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
