技术规格
- 电阻值: 5mΩ
- 功率额定值: 2W
- 温度系数: ±70ppm/℃
- 公差: ±1%
- 封装形式: 2512（标准表面贴装封装）
结构与材料
FMF25FPJR005-LH 使用高导电率合金材料制造，以保证极低的电阻值和良好的电流承载能力。其2512封装设计支持通过贴装技术快速与自动化生产相结合，具有良好的热管理能力，适合大批量生产和集成电路及模块的紧凑型布局。
工作原理
电流采样电阻的基本工作原理是基于欧姆定律（V=IR），即通过在电路中串联一个已知电阻来测量电流。当电流通过此分流器时，电阻上会产生与电流大小成比例的电压降。此电压降可通过 ADC（模数转换器）等方式进行测量，进而获得电流值。FMF25FPJR005-LH 提供极低的电阻，减少了对电路的影响，同时保持高精度的测量结果。

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.
