FMF25FPKR010-LH 产品概述
一、产品简介
FMF25FPKR010-LH 是 PSA（信昌电陶）推出的一款高可靠性电流采样电阻（分流器），封装为 2512。该器件专为精确电流检测与功率监控设计，适用于各种电源管理和电机驱动场合，兼顾低阻值、较高功耗与良好温漂特性。
二、主要技术参数
- 电阻类型：采样电阻 / 分流器
- 阻值：10 mΩ
- 精度：±1%
- 额定功率：3 W（在推荐散热条件下）
- 温度系数（TCR）：±70 ppm/℃
- 封装：2512（SMD）
三、性能说明
- 低阻值带来极小的压降：例如 1 A 电流造成约 10 mV 压降，适合高效率系统的电流监测。
- 额定功率换算：理论极限电流 I = sqrt(P/R) ≈ 17.3 A（3 W、0.01 Ω），实际可通过散热设计与降额使用以保证长期可靠性。
- 温漂影响：±70 ppm/℃ 表示温度变化对阻值的影响较小，例如温度升高 60℃ 时阻值约增加 0.42%，有利于精密测量。
四、主要特点
- 封装 2512，适合自动贴装与工业化批量生产。
- 精度 ±1% 满足多数电流检测与反馈控制要求。
- 良好的稳定性与重复性，适合长期测量与保护电路。
- 适用表面贴装工艺，便于与整机 PCB 散热设计配合。
五、典型应用场景
- 电池管理系统（BMS）电流监测与SOC估算
- 开关电源与电源模块电流采样
- 直流电机驱动与过流保护
- 充电器与逆变器的电流检测电路
六、安装与使用建议
- 建议按系统热设计对电阻进行降额使用，并在 PCB 设计中考虑铜皮散热或热焊盘扩散热量。
- 采用标准无铅回流焊工艺时，应遵循厂家提供的焊接曲线与预热/冷却要求以避免热应力。
- 在高精度测量场合，可采用差分放大器或专用电流检测放大器进行测量，注意接地与布线以减少干扰。
七、可靠性与选型提示
- 选型时除阻值与精度外，应关注工作温度范围、长期功耗循环与实际散热条件。
- 对于脉冲大电流场合，应参考厂家寿命数据并进行必要的热仿真或实际测试。
- 如需额外认证或特殊包装（如卷带、盘装），建议联系 PSA（信昌电陶）或其代理商获取详细资料。

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.
