RLS12FTCR005 为大毅科技(Dayi)推出的一款高精度贴片采样电阻(分流器),封装为常用的 1206,阻值 5 mΩ,额定功率 1W,阻值公差 ±1%,温度系数(TCR)±50 ppm/℃。此器件专为电流检测与功率管理场景设计,适配要求低压差、低功耗、稳定测量的应用。
理论上在额定功率下的允许通过电流 I = sqrt(P/R) ≈ 14.1 A,但该数值为理想计算值,实际使用须根据 PCB 散热条件和环境温度进行功率降额。
总结:RLS12FTCR005 以其低阻值、高精度与较低温漂,适合在要求准确电流采样且空间受限的电子系统中应用。合理的 PCB 散热与布局、配合合适的信号放大与保护电路,可充分发挥其检测精度与长期稳定性。

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.
