RC-01W4701FT 为风华(FH)系列超小型贴片厚膜电阻,阻值 4.7kΩ,公差 ±1%,额定功率 50mW,工作温度范围 -55℃ 至 +125℃。封装为 0201(约 0.6 mm × 0.3 mm),专为高密度、高可靠性、小型化电路设计,适用于移动设备、可穿戴、消费电子和高密度互连电路的去耦与分压等应用。
注意:连续工作时实际允许施加的电压应同时满足功率限制(Vmax ≈ √(P·R))。按 50 mW 与 4.7 kΩ 计算,连续稳态下的功率限制对应电压约 15.3 V;虽然器件标注工作电压 25 V,但在长时间直流施加时应以功率限制为准,避免超过额定功率。
如需更详细的电气参数、温度功率降额曲线、焊接规范或封装机械图纸,请提供具体的采购批次或直接索取风华(FH)官方数据表。

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.
