RLP25FEER030是大毅科技推出的一款贴片式电流采样电阻/分流器,采用2512标准贴片封装,专为中功率场景下的电流精准检测设计。其核心基础参数明确:阻值为30毫欧(30mΩ)、精度±1%、额定功率2W、温度系数(TCR)±50ppm/℃,可满足多数工业及消费电子领域的电流采样需求。
30mΩ为低阻值设计,可有效降低电流采样时的功率损耗,避免对被测电路造成额外影响;±1%的精度等级,能保证在常规工作条件下,采样电流与实际电流的偏差控制在合理范围内,满足电源、电机驱动等场景的基本精度要求。
额定功率2W,结合阻值计算可得持续工作电流约8.16A(公式:(I=\sqrt{P/R}),代入(P=2W)、(R=30mΩ)),峰值电流可根据降额曲线适当提升,适合中功率设备的电流监测(如10A以内的电机驱动、电源输出)。
±50ppm/℃的温度系数,意味着当环境温度变化1℃时,阻值漂移仅为(30mΩ×50×10^{-6}=0.0015mΩ);即使温度波动达100℃,总漂移也仅0.15mΩ,对采样精度影响极小,适合宽温工作环境(如-55℃~125℃常规工业温度范围)。
2512贴片封装(尺寸约6.4mm×3.2mm),体积小巧,可直接通过自动化贴片机焊接于PCB板,兼容性强,无需额外插件空间,适合高密度电路设计。
RLP25FEER030凭借低阻、高精度、高功率密度的特点,广泛应用于以下领域:
RLP25FEER030是一款性能均衡的贴片电流采样电阻,覆盖中功率电流检测的核心需求,兼具低阻、高精度、高稳定性与便捷安装的特点,适配电源、电机、BMS等多领域应用,是工业及消费电子设备中电流监测的高性价比选择。

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.
