RLM12FTCMR050是大毅科技针对中低功率场景精准电流检测推出的贴片式采样/分流电阻,核心参数精准匹配电源管理、电机控制等领域的实际需求:
电流采样电阻的核心作用是将电路电流转化为可检测的电压信号(公式:( V=I×R )),因此低阻、高精度是关键指标。50mΩ的阻值既保证压降可控(如2A电流时压降仅0.1V),又能输出足够电压供ADC采集,1%精度则避免了阻值偏差导致的采样误差。
1206封装尺寸为3.2mm×1.6mm,属于小型贴片封装,具备三大核心优势:
RLM12FTCMR050的1W额定功率(25℃环境温度下),结合50mΩ阻值可计算最大允许电流约为4.47A(( I_{max}=\sqrt{P/R}=\sqrt{1/0.05} ))。实际应用需参考功率降额曲线(大毅建议70℃环境温度下功率降额至0.7W,对应电流3.74A),可覆盖:
除常温±1%精度外,RLM12FTCMR050的温度系数(TCR)约为±50ppm/℃(大毅常规采样电阻特性),有效降低温度波动对阻值的影响:
RLM12FTCMR050凭借低阻、高精度、小封装的特点,广泛应用于以下领域:
大毅科技作为专注电阻研发生产30余年的厂商,RLM12FTCMR050具备可靠的品质保障:
RLM12FTCMR050通过精准的参数设计与可靠的工艺保障,成为中低功率电流采样场景的高性价比选择,适配从消费电子到工业控制的多领域需求。

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.
