SS49EUA 产品概述
一、概述
SS49EUA 是 ElecSuper（静芯微）推出的一款线性霍尔磁场传感器，采用 TO-92S 小型封装，适合位置、速度及电流检测等中低场强线性测量场合。器件对直流或缓变磁场具有线性响应，结构紧凑、使用方便，适合穿孔板或小型 PCB 的低成本设计。
二、主要特性
- 磁场测量范围：±100 mT（±1000 G）
- 灵敏度：2 mV/G（约 20 mV/mT）
- 工作电流：典型 6 mA（静态工作电流）
- 额定工作电压：最高 15 V
- 工作温度范围：-40 ℃ ~ +100 ℃
- 封装：TO-92S 直插封装，便于手工焊接与工程验证
三、性能解读
按标称灵敏度计算，满量程 ±100 mT（±1000 G）时，输出变化量约为 ±2 V，便于与常规放大器、ADC 直接配合。器件为线性输出元件，输出一般以供电电压的中点为基准（需要在电路设计中考虑偏置与测量范围）。6 mA 的工作电流使其在功耗与响应速率之间达到平衡，适合电池供电以及工业供电系统。
四、典型应用
- 无触点位置与行程检测（齿轮、凸轮、限位）
- 直流电流检测（配合磁屏蔽或闭合磁通）
- 角度或速度传感（低速、低频场）
- 工业自动化、家电与消费电子的接近/位置检测
五、使用建议
- 电源稳压与去耦：建议在 VCC 与 GND 之间并联 0.1 μF 陶瓷电容，以抑制电源纹波对输出的影响。
- 偏置与放大：若系统 ADC 接受差分或单端小量程输入，考虑用运放进行偏置调整与增益放大以充分利用 AD 分辨率。
- 磁场方向与安装：安装时确认磁场方向与器件灵敏轴一致，避免横向磁场引入误差；必要时做角度校准。
- 温度漂移：高低温环境会引起偏置与灵敏度漂移，关键应用建议做温度标定或使用温补算法。
- 过磁场保护：尽管器件可工作在 ±100 mT 范围，短时间超限可能造成非线性或损伤，应避免强磁体近距离碰撞。
六、封装与采购
TO-92S 直插封装便于手工调试与小批量生产，外形小巧、成本低。采购时请关注批次标识与静电防护（ESD），并向供应商确认器件的典型 electrical characteristics 曲线与可靠性数据，以满足具体应用的温度和长期稳定性要求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
