RLM10FTSMR020 是大毅科技推出的一款贴片电流采样电阻(分流器),阻值 20 mΩ,额定功率 500 mW,精度 ±1%,温度系数(TCR)±50 ppm/℃,封装为 0805。该器件专为低阻值、高精度电流检测场合设计,适合与电流检测放大器、模数转换器(ADC)配合使用,实现对直流或低频交流电流的精确监测。
0805 小封装适合体积受限的电路板设计,但热容量有限,长时间大电流工作需关注结温和环境温度。大毅科技的产品通常经过焊接耐久性与温度循环测试,具体可靠性数据请参照厂商产品规格书或与供应商确认。
下单时请确认完整型号 RLM10FTSMR020、阻值公差、包装形式(卷带或散装)及样品可用性。实际应用前建议获取样品进行热升温、长期漂移与 PCB 参考设计验证。若需替代方案,可考虑更大封装功率更高或更低 TCR 的分流器。
如需进一步的电气特性曲线(阻值随温度曲线、长期漂移)、封装尺寸图或 PCB 布局建议图,我可以基于具体应用给出更详细的设计指南。

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.
