RLM25FEER002是大毅科技推出的一款贴片式电流采样电阻(分流器),专为中大功率电路的电流精准监测设计,核心参数覆盖工业级与汽车电子等场景的基础需求:
RLM25FEER002采用2512贴片封装,尺寸为6.35mm×3.05mm(0.25英寸×0.12英寸),符合电子行业标准化规格,具备以下安装优势:
低阻精准采样
2mΩ毫欧级阻值是电流采样的关键优势——自身压降仅约63mV(31.6A时),对原电路功率损耗与信号干扰极小;±1%精度可稳定输出电流反馈信号,避免因阻值偏差导致控制误差。
宽温稳定特性
±50ppm/℃的温度系数意味着:在-55℃~125℃工作范围内,每变化1℃阻值仅变化0.005%,大幅降低高低温波动对采样精度的影响,适合户外、工业车间等恶劣环境。
可靠功率承载
2W额定功率可长期稳定工作,同时支持短期脉冲过载(如10倍额定功率1秒内冲击),应对电路瞬时大电流(如电机启动、电源切换)时不易损坏,提升系统抗干扰能力。
RLM25FEER002的性能适配多类中大功率系统:
大毅科技作为国内电阻制造领域的成熟厂商,RLM25FEER002具备完善的可靠性保障:
RLM25FEER002以高性价比、稳定性能成为中大功率电路电流监测的优选元件,覆盖工业控制、汽车电子等多行业应用。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
