RLP25FEGR020 是大毅科技推出的一款高精度贴片型电流采样电阻(分流器),封装为行业常用的 2512(约 6.35 × 3.2 mm),额定功率 3 W,阻值 20 mΩ,公差 ±1%,温度系数 ±50 ppm/℃。该器件专为需要低压降、高稳定性电流测量场合设计,适配开关电源、电池管理、充电桩、电机驱动和电流监控等系统。
性能亮点:极低阻值带来较小的电压降,TCR 优秀以保证测量一致性和长期稳定性,1% 精度满足多数电流测量和保护控制场景需求。
注意:上述计算为理想静态条件,实际允许电流受 PCB 散热、环境温度、脉冲负载特性影响,应结合热设计与稳态/脉冲功率能力做具体评估与余量设计。
RLP25FEGR020 具备较低 TCR 与高功率密度,适合要求长期稳定和高重复性电流测量的应用。在采购时建议关注批次一致性、出厂测量报告(阻值、TCR、功率测试)及是否符合 RoHS 等环保要求。对于特殊温度或高可靠性需求,可与生产方沟通定制测试或筛选服务。
如需进一步的封装尺寸图、PCB 推荐焊盘或浪涌/脉冲功率曲线,可联系大毅科技或其授权代理获取完整数据手册与应用指导。

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.
